How large of a room would 1 uv flood 36 light cover? Would it be good for a 16x14 foot room?
Well the coverage is about 4 lux at 16 feet in distance and 16' in width. You may find that the UV PANEL HP will have more output at 160W of Black light as opposed to 36W of output in the UV FLOOD 36. The UV PANEL HP will cover a 25x25 foot floor from 15 feet in the air.
using power cord daisy chains, will one remote control all units in that chain?
No. The power cords do not transfer data. You'll need to set these fixtures in master slave mode and daisy chain them using 3-pin DMX cables.
