I will get some pictures when I get home. I have rapidled diy with 6 1/2 heatsink with t5 retro fit on either side facing inward(towards center). my leds were old as well about 4 years I kept some replaced the blown ones and added a few my drivers. I can say I'm glad I replaced the cool whites with some warms and neutrals. And replaced some royals with uv/violets and added a completely new string with standard blues. I made my "colored" string red,green warm white,cyan,lime in retrospect I would have kept the
green,lime,cyan on one channel
And
Red, warm white, orange on a seperate channel and made it more Controllable.
But that's an extra 50$ in drivers and an extra vdm module which wasn't in the budget at the time, I may at one point adjust but it's working well now. I did have a hard time rebuilding my unit due to cost when I see new fixtures nearing the led cost... prices have dropped dramatically since the 4 years ago when I first built the fixture.
