Updated document with how I assemble inside the Ebay flood enclosure. I was wondering can I drive the board by using a 3 channel DMX controller? The seals were tacked in with hot glue and all 4 screws were used to mount the LED. Also have a ren48lsd currently driving rainbow floods with several LEDs burned out. I will make the video in a day or two. BTW, I have 2 new boards on the way. Has anyone any experience with this cable and know where I can buy it cheaper? Please point to your store when this and the dmx controllers are available. Depending on your cable run length you may need to tweak the resistor values due to voltage drop so you will have to do the math there.
The PT includes the power switch and a high-side.

One possible solution that would not require much rewiring could be setting ch4 to on and using that as a common ground.
Thought about putting small PS in floodlight itself but space was tight and figured emi would impede wireless reception more than the metal reflector and case does. I have some of the old boards. Still missign resistors which together with jumpers will allow selectable current. The board can work with common anode LEDs?
Has anyone found a lower cost supply of cases to put the 20 watt module into?

You can count me in for one test batch or final version as soon as they are ready, plus at least 5 driver board kits. Rob, if the group buy are the v3 boards, I'd put in for 10 of them and we can cancel the order I just made Sent from my iPad using Tapatalk.

The eBay ones were much easier to strip and actually a little better in quality. So I will be testing LED's prior to build as well as verify functionality twice before they go in the housings. Guess that's why: Last issue was that on about 6 of my boards from oshpark, the green negative trace off the triac to the corresponding pad was shorted to the ground plane.

V AC,V or V AC mains power. One user claims it uses the XL driver chip (datasheet - not presently linked from their 1, 17 mm, Uses PT driver chip (see notes on PT below) with SS14 Schottky diodes.
If we do one per 4 channels or one for the whole board, than we would have to use 7.

Well that info changes things certainly. I grabbed one of the cheap 10W RGB floods to play with and was pleased with the output. Makes you wonder if these 10w LED's are taking this much power, how are the 10W's going to run at 12v? I am willing to test them.

|There is no control on how the current is divided between all the parallel LED strings, and it may end up with some string got more current than others, and run hotter, and draw more share of the current and run even hotter.
Problem is the LED that went bad, removing caused me to remove the solder beds on the pcb, so that's a weird repair I may not want to make : Tory.
Well I tested, figured it would be on me if something busted. Below are specs, board and worksheet for what I was playing with if interested. I've been hunting unsuccessfully.
