Supra, can we go back to this? Do you have any links for the drivers that you settled on? Any further info, such as whether this is one driver per COB, etc. would be great. If I try a DIY LED it'll be a copy/paste of something you made!It was a very hard decision ended up with a set of drivers that range from 680mA to 740mA. They are 84% efficient and power factor corrected. I really wanted to use the fasttech 650mA but once they warm up some of them are as low as 630mA at 34vF which really underutilizes the heatsink and the COB because there isnt much efficiency to be gained by running that soft.
Literally 2700k alone works wonders. Get the same as bbspills did and you will not be disappointed. growth by the hour5000K, 9000 luminous flux
Good thing I'm rockin' two monitors... I pulled up Cree's 3070 .pdf on one screen, and Mouser's 3070 page on the other screen. Scratched my head for a while, then started applying filters. I asked for 5000K, then highest luminous flux, which was 9000.
Here's what I came up with. Mouser appears to stock 4 that meet those criteria. If any of the LED experts have got a minute, are all four of those good choices?
In 2700K, the highest lm available appears to be 7390 (?) Here's that page. Same question I guess - are those good choices for covering the warm end of the spectrum?
Here's the spectrum chart from Cree:

To my untrained eye, a mix of 5000K and 2700K oughta do the trick?
