DIY LED Using 10 Watt Arrays

[mike31154]

Annual update of this dinosaur thread. 6 years running this fixture now and it may be time for a refit or upgrade. One of the LEDs finally failed a few months back & I replaced it since I have spares on hand. Another one went recently & several more are on the way out, losing a string of 3 on the chip. Seems the Royal Blue, Blue ones are failing before the Whites. No more spares on hand, so I'm faced with the decision to order more or do a major upgrade with newer multi colour multi chips available these days.

Wondering if it's even worthwhile, there has been so much progress in LED development & costs have come down substantially. Is anyone doing DIY LED fixtures anymore?? How are folks' commercial fixtures, Radions etc. holding up? Tempted to go to fewer higher wattage multi colour chips, but ordering more of the 10 watters & replacing them would be a lot easier than a redesign/build.
