Currently running two 50w on the wall, covers a 96”x84” area
My 6' light puts out 4000 lumens at 5000k (theoretically, I don't have a light meter) and "equals" 300 watts of incandescent light from from only 40.8 watts. It actually seems that each puck puts out the heat of a 10w bulb but the light of a 60.
It's ingenious: they clip off half the AC current and invert it, then filter it, to make a not-quite-DC to run the LEDs. That's one function of the regulators. I exposed this by setting the internal control too low. LEDs don't heat up as fast as a filament, and where a filament would glow weakly, the LED will flicker at some critical point. I crossed it.
But if you never cross those points, you never know where they are.
While I was repairing the one solder joint I'd blown (well actually changing that puck) it occurred to me that I might have damaged the regulators. With 20% less load they could overdrive the LEDs. I saw no evidence of that, and all the chokes are operating at the same temperature. I did find that the puck furthest from the regulators had toasted one of its 20 LEDs and it was rather yellow. I didn't consider that that puck had the longest wires, and therefore the most resistance.
I left enough space in the Lexan box for a timer, but I haven't looked for one yet. I'm thinking of maybe a Bluetooth thing I can set from my phone.
