Luxeon Vs Cree and other DIY Q

Mike's LEDs, 27 no name 10 watt multichips mounted on individual heatsinks with fan attached to thin aluminum angle. Mixture of 6500K white, 10000K white, blue & royal blue.

Lightweight & been going strong for over 1 year. I've had to replace a few of the fans, they're quite small and cheaply made, but the price was right & I have plenty of spares. I understand even high end lights like Radions have had some fan issues, so.... I can live with my cheapies. But I'm considering a top for my fixture which will include a couple of larger, heavy duty fans. Might be able to ditch the little ones then, since that's 27 fans for 27 LEDs.




A few months ago I added a couple of 5050 SMD RGB strips along the center rail of 10 watt chips. Works great for dawn/dusk.

A plate heat sink with fins is not old fashioned and is superior to a tube. It has way more surface area and can accept more convection. Those are really the only two variables here.
