To initiate a warranty claim, contact ADJ's service department by phone at (323) 582-2650, Monday through Friday, 8:00 AM – 4:30 PM Pacific, or by email at support@adj.com. Have your fixture's model name, serial number, proof of authorized purchase, dealer information, and a clear description of the failure ready when you call or write. ADJ will issue a Return Authorization number (RA#) if depot service is required. Do not ship any unit to ADJ without an RA# — units received without prior authorization will experience significant processing delays and may be returned unserviced at your expense. The RA# must be clearly marked on the outside of the shipping carton. Ship the fixture in its original packaging when possible. Use a rigid box with adequate padding — damage sustained in transit due to insufficient packaging is not covered under warranty and will be billed at standard out-of-warranty repair rates. Insure the shipment for the fixture's replacement value. ADJ will advise on shipping destination when the RA# is issued.

ADJ's warranty is void under several clearly defined conditions. Physical damage from misuse, drops, or accidents is not covered — the warranty addresses factory defects, not field damage. Unauthorized modifications to the fixture, including internal electrical changes, firmware modifications not authorized by ADJ, or structural alterations, will void coverage. Operation outside the fixture's rated specifications — supplying incorrect voltage, exceeding rated duty cycles, using the fixture in weather conditions beyond its IP rating, or running it in temperatures outside the stated operating range — voids the warranty. Normal wear items such as cooling fans, air filters, and fuses are not covered under the standard warranty and are expected to require periodic replacement. Purchase from an unauthorized source is itself a warranty-voiding condition. If the product was not purchased new from an ADJ-authorized dealer, ADJ may decline warranty service. Additionally, removal or alteration of the fixture's serial number tag voids warranty coverage entirely — ADJ requires the serial number to verify product identity and manufacture date.

ADJ's warranty covers manufacturing defects — it does not cover everything that can go wrong with a fixture. Understanding the exclusions saves time when deciding whether to contact ADJ service or pursue other repair options. Exclusions include: physical damage from impact, drops, or water ingress beyond the fixture's IP rating; damage from power surges, incorrect supply voltage, or improperly wired electrical systems; failure resulting from unauthorized repair or modification; cosmetic damage such as scratches, dents, and finish wear; consumable components including cooling fans, air filters, fuses, and lamps; and damage caused by failure to follow the product's operating instructions. Normal LED output degradation over time is also not a warranty issue — all LED arrays dim gradually over their operational lifespan. Warranty applies to premature or sudden failure that is consistent with a manufacturing defect, not gradual lumen depreciation from normal use. If your fixture shows a sudden, dramatic loss of output and is within the warranty period, that's worth a warranty claim conversation with ADJ service.

In most cases, yes — performing internal service on a fixture yourself, or having it serviced by an unauthorized shop, will void the warranty. ADJ's warranty covers defects that originate at the factory, and warranty service is performed by ADJ's authorized service department. Unauthorized internal access makes it difficult to determine whether a subsequent failure is factory-related or was caused by the unauthorized service work. If your fixture is within the warranty period and experiencing a defect, the correct path is to contact ADJ service for an RA# and let ADJ's technicians handle the repair. Attempting a self-repair on a fixture under warranty risks both the repair itself and your remaining coverage. For fixtures outside the warranty period, self-service using OEM parts from americandj.com is entirely viable and something ADJ actively supports by making parts available to end users. ADJ Hardware Manager (free download from adj.com) provides additional access for settings and firmware without requiring the fixture to be opened. If you're unsure whether your fixture is in or out of warranty, contact ADJ service before opening the unit.

ADJ's warranty coverage is regional. Products purchased in the United States through an authorized US dealer are covered under ADJ USA's warranty terms. Products purchased through ADJ Europe or an authorized European distributor are covered under ADJ Europe's warranty terms and are serviced through ADJ's European service infrastructure. For US customers who purchased a fixture internationally (or vice versa), warranty service may still be available but may require the unit to be routed to the appropriate regional service center. Contact ADJ USA at (323) 582-2650 or ADJ Europe at +31 (0)45 546 85 00 to discuss coverage options for cross-region purchases. Purchases made through unauthorized international grey-market channels — where a product intended for one market is sold in another without the manufacturer's authorization — are generally not eligible for warranty service in either region. If you're buying imported ADJ products, verify that the seller is an authorized ADJ dealer in your region before purchasing to ensure warranty coverage applies.

ADJ product registration is handled through the adj.com website or by contacting ADJ support directly. While registration is not a prerequisite for warranty coverage — your proof of authorized purchase (receipt or dealer invoice) is the primary document required — registering your product creates a service record that can streamline future warranty claims and support interactions. To register, visit adj.com and look for the product registration option under the Support section, or contact support@adj.com with your product's model name, serial number, purchase date, and dealer information. ADJ service can associate this information with your account for future reference. Keep your original purchase receipt regardless of whether you register. In any warranty situation, ADJ will request proof of authorized dealer purchase, and a dated receipt from an authorized ADJ dealer is the definitive document. Digital copies stored in email or cloud storage are acceptable — you do not need the physical receipt as long as you can produce a legible copy.

Yes, myDMX hardware — including the myDMX 5 interface, myDMX 3.0 interface, myDMX Buddy, myDMX Amigo, and other ADJ control hardware — is covered under ADJ's standard limited warranty against manufacturing defects. Coverage follows the same authorized-dealer-purchase requirement as ADJ lighting fixtures. Common myDMX hardware failure modes that are covered under warranty include: the USB interface not being recognized by the host computer after following correct connection procedures; CRP DISABLED errors that appear immediately upon purchase or after minimal use (as opposed to errors caused by improper handling or power interruptions); and hardware-level failures of the interface itself. Before submitting a warranty claim on a myDMX interface, ADJ support will typically ask you to attempt recovery using Hardware Manager — the free ADJ utility downloadable from adj.com product pages. Hardware Manager can reflash the interface firmware and resolve many CRP DISABLED and non-recognition issues without requiring depot service. If Hardware Manager cannot recover the interface, ADJ service will issue an RA# for warranty repair or replacement.

ADJ technical support is available by phone and email during US business hours. The primary service and support line is (323) 582-2650. Support and service hours are Monday through Friday, 8:00 AM – 4:30 PM Pacific. For email support, contact support@adj.com — email is the preferred channel for non-urgent technical questions, documentation requests, and firmware inquiries where attaching photos or files is helpful. For sales inquiries — dealer contact, new product information, volume pricing questions — reach ADJ's sales team at sales@adj.com, Monday through Friday, 8:00 AM – 5:30 PM Pacific. ADJ Europe handles support for customers in Europe and nearby regions: phone +31 (0)45 546 85 00, service email service@adj.eu. If you're in Mexico, ADJ's Mexico office can be reached at +52 (728) 282.7070. For community-based technical discussions, the ADJ User Forum at forums.adj.com is an active resource where ADJ users share troubleshooting solutions, setup tips, and fixture-specific guidance. The forum is a useful complement to official support for non-warranty questions and general how-to topics.

Product manuals, DMX channel charts, and other technical documentation for every ADJ fixture are available for free download on each product's individual page at adj.com. Navigate to the fixture's product page and scroll to the Downloads section — you'll find PDF user manuals, DMX trait documents (channel maps and mode descriptions), and CAD/3D drawings for mounting and rigging planning. This is the single most reliable source for fixture-specific documentation. Every ADJ product page maintains its own download library, so you can always retrieve the correct documentation for your specific model and ensure you have the current version. ADJ does not currently maintain a centralized documentation hub — downloads are organized by product page. For older or discontinued fixtures, documentation is typically retained on the product page even after a product is discontinued. If you cannot locate a manual for an older fixture, contact support@adj.com with the model name and serial number — ADJ's support team can provide legacy documentation directly.

ADJ software downloads are available from adj.com product pages rather than a single centralized download hub. For myDMX software (myDMX 5, myDMX 3.0, myDMX GO), navigate to the relevant myDMX product page in the myDMX section of adj.com — the current software installer and release notes are in the Downloads section of each product's page. Hardware Manager — ADJ's free firmware and device management utility — is available in the Downloads section of individual fixture product pages. Not every product requires Hardware Manager, but it's available for any ADJ fixture that supports USB-based firmware updates or configuration. WTOOLS, the lower-level USB recovery utility, is similarly found on relevant product pages. For Compu Show and other third-party or licensed ADJ software platforms, visit the software developer's site or contact ADJ sales for current licensing and download information. The myDMX upgrade and extended-feature store is at store.dmxsoft.com, where additional universes and feature unlocks for myDMX 5 are available. If you're looking for a specific software download and can't locate it, contact support@adj.com or the ADJ User Forum — forum members are often the fastest source for locating obscure download links.

Yes. ADJ's service department accepts out-of-warranty fixtures for depot repair. The process starts the same way as a warranty claim — contact ADJ service at (323) 582-2650 or support@adj.com to describe the fault and receive an RA# before shipping anything in. For out-of-warranty repairs, ADJ will diagnose the fixture and provide a repair quote before any work begins. You are not obligated to authorize the repair — if the quote exceeds what makes sense for the fixture's value, ADJ can return the unit unrepaired (shipping charges apply). Out-of-warranty moving head repairs involving LED and driver replacement have typically run $400 or more plus return shipping, so getting the quote and weighing it against the fixture's replacement cost is always the right move before authorizing. As an alternative to depot service, ADJ makes most repair parts available directly at americandj.com. For technically capable users, DIY repair with OEM parts is often more economical than depot service for common failures like cooling fans, fuses, and driver boards. ADJ's Hardware Manager utility provides additional capability for settings-level repairs and firmware recovery without opening the fixture at all.

Yes. ADJ maintains a showroom at its Los Angeles headquarters — 6122 S. Eastern Avenue, City of Commerce, CA 90040. The showroom is open to both dealers and the public, but visits are by appointment. Contact the showroom manager, Ted Molina, to schedule a visit: phone (323) 213-4504 or email ted.molina@adj.com. The showroom gives you the opportunity to see current product lines operating firsthand, evaluate fixtures in person before purchasing, and speak directly with ADJ's team about product selection for your application. If you're specifying fixtures for a significant project — venue installation, fleet purchase, or touring production — a showroom visit is a worthwhile step before committing to a large order. For customers outside Southern California, ADJ also participates in major industry trade shows including LDI, Prolight+Sound, and regional events throughout the year. Connecting with an authorized ADJ dealer in your region is typically the most practical path for product evaluation outside the LA area.

ADJ's 2-year limited warranty is tied directly to authorized dealer purchases. Buying from an unauthorized source — including many third-party Amazon sellers, eBay listings, grey-market retailers, and private sellers — means your fixture may have no manufacturer warranty coverage even if it fails within what would otherwise be the warranty window. ADJ requires proof of authorized purchase to process any warranty claim. Authorized ADJ dealers receive genuine, properly imported product with full manufacturer documentation and appropriate regional certifications. Grey-market imports may lack proper US safety certifications, may have been intended for different voltage specifications, or may be counterfeit products — all risks that disappear when purchasing through the authorized dealer channel. Beyond warranty and product authenticity, authorized dealers offer knowledgeable pre-sale guidance, proper system design support, and post-sale backup that a grey-market seller simply cannot provide. For working professionals where equipment failure at a show is a real cost, the authorized channel isn't just about warranty — it's about buying from someone who has skin in the game when something goes wrong.

ADJ maintains an authorized dealer locator at adj.com/pages/dealer-locator. Enter your location to find authorized dealers in your area. ADJ's dealer network spans the United States and extends internationally — the locator covers dealers globally. For customers in the US, authorized ADJ dealers include major professional audio-visual and lighting retailers as well as specialized entertainment lighting dealers. If the dealer locator doesn't surface a nearby option, contact ADJ's sales team at sales@adj.com — they can connect you with the appropriate dealer or distributor for your region and market segment. For international markets outside the US and Europe, ADJ maintains regional distributors listed at adj.com/pages/distributors. Purchasing through the in-region distributor or their authorized sub-dealers is the correct path for ensuring warranty coverage and proper support in your country.

ADJ does not sell direct to end users through adj.com — the site shows products without pricing for a reason. All ADJ purchases are made through the authorized dealer and distributor network. This is by design: the dealer channel ensures you receive the product with proper support, warranty coverage, and competitive market pricing. The americandj.com/parts site is a separate, parts-specific platform where individual replacement and repair parts can be purchased directly. This is for service and maintenance purposes — not for fixture purchases. If you're looking to buy ADJ fixtures, use the dealer locator at adj.com to find an authorized dealer in your area. ADJ's sales team at sales@adj.com can also recommend a dealer suited to your specific application — whether that's a rental house, production company, installation contractor, or DJ supply dealer.

ADJ works through its authorized dealer network to provide competitive pricing for production professionals, rental houses, installation contractors, and volume purchasers. Pricing and program structures are negotiated between ADJ and its dealer partners — your authorized ADJ dealer is the correct contact for pricing discussions on specific projects. For significant purchases — fleet builds for rental houses, large installation specifications, touring production packages — contact ADJ's sales team at sales@adj.com or call the sales department at (323) 582-2650. The sales team can connect you with a dealer experienced in your market segment and help ensure the quote is structured appropriately for your project scope. ADJ also works with programs for qualifying organizations such as houses of worship, educational institutions, and non-profits in some regions. These programs are dealer-administered — contact ADJ sales or your local authorized dealer to inquire about current program availability and eligibility for your organization.

A discontinued ADJ product has reached end-of-production — ADJ is no longer manufacturing or distributing that model. The product's page remains on adj.com under the Discontinued collection, and product documentation (manuals, DMX charts) is typically retained for continued service and support reference. Discontinued status does not affect warranty coverage on units already in use — the 2-year warranty from original purchase date remains valid regardless of whether the product is still in production. ADJ service will still support warranty claims on discontinued products within the coverage window. For parts and service on discontinued fixtures, availability varies. Contact ADJ service at support@adj.com or (323) 582-2650 to check parts availability for a specific discontinued model before assuming parts are in stock. Older discontinued products may have limited parts availability, which is a factor when evaluating whether to repair or replace an aging fixture. When building or expanding a production inventory, it's worth verifying that a fixture you're specifying is current production — purchasing discontinued product at closeout pricing can be attractive, but factor in the limited future parts and service support.

ADJ (American DJ) is a global manufacturer of professional entertainment lighting, LED video, and atmospheric effects equipment headquartered in Los Angeles, California. Founded in 1985 and now marking over 40 years in the industry, ADJ develops and sells moving head luminaires, LED wash fixtures, strobe and effects lights, DMX control hardware and software, atmospheric generators, LED video panels, and a full range of supporting accessories. ADJ is one of the most widely deployed entertainment lighting brands in the world. Its products are used at events, productions, and festivals of all sizes — from mobile DJ setups and small club installations to large-scale touring productions, concert venues, houses of worship, theaters, trampoline parks, nightclubs, and corporate event centers. The company is known for combining professional-grade performance with accessible pricing and a deep support infrastructure including the ADJ User Forum, Hardware Manager tools, and a dense authorized dealer network across the US and internationally. ADJ is part of the larger ADJ Group of Companies, which spans multiple brands across lighting, audio, trussing, and cabling.

ADJ is the flagship brand of the ADJ Group of Companies — a portfolio of complementary brands spanning professional lighting, audio, trussing, cabling, and control systems. The full brand family includes: ADJ Lighting, Elation Professional, Avante Audio, American Audio, Acclaim Lighting, Magmatic Effects, Obsidian Control Systems, Eliminator Lighting, Global Truss America, DuraTruss, Accu-Cable, and Accu-Stand. Each brand in the ADJ Group serves a distinct market segment or product category. Elation Professional addresses the touring and high-end installation market with premium fixtures. Avante Audio and American Audio cover professional and DJ audio equipment. Acclaim Lighting is a residential and commercial decorative lighting brand. Magmatic Effects specializes in special effects equipment. Obsidian Control Systems develops the ONYX lighting control platform used by touring professionals worldwide. For hardware and accessories, Accu-Cable covers professional cables (DMX, audio, power), Accu-Stand provides lighting stands and rigging accessories, Global Truss America and DuraTruss handle structural trussing systems, and Eliminator Lighting offers budget-tier DJ and club lighting at accessible price points.

ADJ and Elation Professional are sister brands under the same parent organization, the ADJ Group of Companies. They are not the same brand, but they share the same corporate ownership, some development resources, and certain technology platforms — including the Aria X2 wireless management ecosystem, which is integrated across both product lines. The brands serve different market segments with different positioning. ADJ is focused on a broad market spectrum — from mobile entertainers and clubs to rental production and installed applications — with a combination of accessible pricing and professional performance. Elation Professional is positioned at the upper tier of the market, targeting touring productions, large-scale events, major venue installations, and applications where the highest-specification fixtures are required. The practical distinction for buyers: if you're equipping a DJ rig, club, house of worship, or mid-tier production, ADJ is typically the right conversation. If you're specifying for a touring production, large arena venue, or high-spec installation where the fixture roster demands maximum performance and premium build quality, the conversation shifts to Elation Professional. That said, ADJ's current Hydro series and Focus CMY-class fixtures occupy genuinely professional territory — the lines have converged at the top of the ADJ range.

Eliminator Lighting is a budget-tier sub-brand under the ADJ Group umbrella. ADJ acquired Eliminator Lighting — which had been an independent brand with over 15 years in the business at the time of acquisition — and continues to operate it as a distinct brand targeting the entry-level DJ, club, and mobile entertainment market. Eliminator Lighting products occupy a lower price point than ADJ-branded products, with a product line focused on affordable LED pars, compact moving heads, fog/bubble machines, and entertainment accessories primarily for the consumer and prosumer DJ market. Eliminator is a separate line from ADJ proper — it is not a rebranded version of ADJ fixtures. For buyers, the distinction is primarily about application and budget. Eliminator is the right conversation for entry-level DJs and budget buyers who need functional equipment at minimal cost. ADJ covers everything above that tier, from prosumer through professional rental and production. If you're equipping a professional setup, ADJ is the correct product family — Eliminator is not intended for demanding production or installation use.

Accu-Cable is ADJ Group's professional cable brand, designed specifically for entertainment lighting and audio applications. Accu-Cable products include DMX cables (including the Tour Link 5P series of 5-pin professional touring-grade DMX cables), audio cables, power distribution cables, IP65-rated locking power cords for outdoor fixtures, and data cables for LED video applications. Accu-Cable DMX cables are engineered to the cable specifications required by the DMX512 standard — proper impedance matching (110 ohms), shielded construction, and reliable connector termination. Using properly rated DMX cables (as opposed to generic XLR audio cables) is a meaningful factor in signal integrity, particularly over longer runs or in electrically noisy environments. Accu-Stand, a companion brand, covers lighting stands, clamps, and rigging accessories. Accu-Cable products are sold throughout the ADJ dealer network and are featured as accessories across ADJ fixture product pages. They're a practical choice when building or specifying cable infrastructure for ADJ-based rigs — not because they're required, but because they're matched to the technical specs of the fixtures they're sold alongside.

ADJ's worldwide headquarters is in the Los Angeles area: 6122 S. Eastern Avenue, City of Commerce, CA 90040. The facility includes ADJ's US sales, service, support, and showroom operations. The showroom is open by appointment to both dealers and the public — contact showroom manager Ted Molina at (323) 213-4504 or ted.molina@adj.com to schedule a visit. ADJ also maintains a significant European presence through ADJ Europe, based in Kerkrade, the Netherlands: Junostraat 2, 6468 EW Kerkrade. ADJ Europe handles distribution, sales, and service for European markets, reachable at +31 (0)45 546 85 00 or info@adj.eu (sales) and service@adj.eu (service). A Mexico operations office is also maintained at Av. Santa Ana 30, Parque Industrial Lerma, Lerma, Mexico 52000, phone +52 (728) 282.7070. The global footprint reflects ADJ's position as a genuinely international brand with regional support infrastructure rather than a US-only operation with nominal international distribution.

Many ADJ fixtures carry CE marking (European conformity) and/or ETL listing (US/Canada safety certification administered by Intertek, equivalent to UL). Certification varies by product line and market — not all ADJ products carry all certifications, and certification status is specified in each fixture's product documentation. For North American deployments, ETL listing (or UL listing) is the relevant certification. ETL and UL listings confirm that the product has been tested to ANSI/UL safety standards for electrical safety, and are commonly required by venue operators, rental companies, and theatrical production companies as a condition of use. CE marking is required for European market sales and covers electrical safety, EMC, and RoHS compliance. The certification status of a specific fixture is listed in its spec sheet and on its product page at adj.com. For critical applications — touring productions, permanent venue installations, and any situation where a venue or AHJ (Authority Having Jurisdiction) may require proof of certification — verify the specific fixture's listings before specifying or purchasing. ADJ's sales and support team can provide certification documentation for specific products on request.

ADJ laser products sold in the United States are designed and labeled in compliance with FDA CDRH (Center for Devices and Radiological Health) regulations under 21 CFR Part 1040. These regulations classify laser products by hazard class and mandate specific safety features, labeling, and performance requirements. ADJ's US-market laser products meet the compliance requirements for their hazard class as shipped. It's important to understand that FDA compliance is a manufacturer-level certification that applies to the product as designed and sold. Operating laser products in ways that exceed their design parameters — removing safety interlocks, bypassing shutter mechanisms, modifying output, or using the product in a manner inconsistent with its operating instructions — creates compliance violations that fall on the operator, not the manufacturer. For venues and productions deploying ADJ laser fixtures: check the specific product's documentation for its FDA hazard class (Class IIIa/3R or Class IIIb/3B, depending on model), follow all operating instructions regarding audience scanning zones and minimum throw distances, and ensure your operators are familiar with applicable FDA laser safety requirements. When in doubt, consult with a Certified Laser Safety Officer (CLSO) for productions where audience scanning or Class IIIb lasers are involved.

ADJ-branded fog and haze fluids are water-based formulations designed for use in entertainment environments. When used in ADJ-compatible machines at recommended concentrations and output levels, the fluids are generally accepted by venue operators and fire marshals and have been tested for compatibility with ADJ's atmospheric equipment lineup. For fire code compliance: venue operators in the US should consult NFPA 160 (Standard for the Use of Flame Effects Before an Audience) and their local AHJ for applicable regulations on atmospheric effects. NFPA 160 includes specific provisions for fog and haze effects in occupied venues. Many venues require prior approval from their fire marshal for use of atmospheric effects, regardless of fluid formulation. Using ADJ-branded fluids and providing the fluid's Safety Data Sheet (SDS) to venue management proactively is the correct approach. For HVAC and residue concerns: all water-based fog fluids can leave a fine residue on surfaces and may affect HVAC filters in recirculating air systems. Output levels and ventilation should be managed per the venue's specifications. ADJ's hazer fluids are formulated for lower residue output than standard fog fluids — for applications where surface contamination is a concern, hazers run at appropriate levels for the space are the better choice over high-output fog machines.

LED flickering on ADJ fixtures usually falls into one of three categories: DMX signal issues, fixture hardware faults, or temperature/power problems. **DMX-related flickering:** A noisy or interrupted DMX signal is the most common cause. Test by disconnecting DMX and running the fixture in standalone/sound-active mode — if flickering stops, the issue is in your DMX chain, not the fixture. Check all DMX cables for damage, verify termination at the end of the chain, and look for address conflicts (two fixtures set to the same address). **Individual LED flicker (hardware fault):** If specific LEDs within a fixture flicker in a random, non-patterned way — with no correlation to DMX changes — this points to an LED driver or individual LED die failure. The Mega TRI Bar and similar multi-LED fixtures are particularly susceptible to individual LED failures. This type of flickering won't be fixed by software or settings changes; it typically requires LED or driver board replacement. **Temperature and power:** The Focus Spot 4z and similar moving heads can show light output irregularities when running hot. Set the fan to HIGH in the system menu to lower internal temperature. If the fixture flashes once on power-up then has no output, this may indicate a power supply failure rather than LED flickering. As a general rule: if flickering is present in standalone mode with no DMX connected, the issue is internal hardware. Contact ADJ service at (323) 582-2650 to discuss warranty coverage or repair options.

Dim output on ADJ fixtures typically has one of four causes: a settings issue, a temperature problem, an LED degradation issue, or a DMX configuration problem. **Check settings first:** Many ADJ fixtures have a global brightness limiter or maximum brightness setting in the system menu. A previous user may have reduced the global output. On fixtures like the DOTZ T Bar, there's a manual dimming mode in the system menu that overrides max brightness globally — check this setting and restore it to 100%. Also check DMX channel values: ensure your dimmer channel and any color channels are at maximum. **Temperature management:** On moving heads like the Focus Spot 4z, high internal temperatures can cause the fixture to reduce output as a protection measure. Navigate to the system menu and set the fan speed to HIGH. After the fixture cools down (give it 10-15 minutes at lower output), see if full brightness returns. If the fixture is running hot regularly, ensure it has adequate airflow. **LED degradation (age/hours):** All LED arrays lose output over time — this is normal. If a fixture has heavy hours and output is noticeably below what it was new, LED replacement may be needed. For lamp-based fixtures like the Vizi Beams 5R, check whether the lamp life counter needs to be cleared (see the lamp hours FAQ). **Warranty path:** If brightness degradation appeared suddenly rather than gradually, and the fixture is within its 2-year warranty, contact ADJ service — sudden output loss is often a driver board failure covered under warranty.
