3’x4’ fixtures using 4’ Bridgelux EB gen 2 strips, with Meanwell drivers. 1"x2" wooden frames
They’ve been going strong for over 3yrs now
There are plenty of pics of the lights here, over on my Circus thread.
@Mr.Sparkle showed me & my son how to make em. Well, he showed us what we needed and the wiring up, son made the frames from extra wood laying around.
edit… actually, this one pictured is two of the original fixtures combined. So the cost for this one would be about $220.00 and equivalent to 1200Watt.
We were running (8) 600watt HPS & MH along with (16) 4’ dbl fluorescent shop fixtures. The electric bill for this entire property was $500-$750 per month. Now when all the lights are in use for entire property electric runs 250-350 month
The electric bill covers the entire property, commercial grow-op and house.
