He supplements with an UV-B reptile light (I think) which would compensate somewhat for the lack of blue;
He has Cree CXA which have a lot more blue (and less red) than the Bridgelux Vero at the same stated color temp...
Lenny I measured the chip area and it's 1x1mm^2 which would make it 42 mil. Didn't know the rule about "42 mil = 2W, 45 mil = 3W". I have a 620nm red off the same size so this must then be 2W as well.
About the efficiency of the Epileds, you are saying that a luxeon is 2 or 3 times more...
Nice to see the exact same chip pattern in these specs, thanks for the link. I think (hope) that the document is outdated as it is over three years old. Either that or I was scammed... Satisled sells this LED as a 660-670 nm chip that can take 750mA. After a bit of testing they seem to tell the...
For reference, here is a mugshot of a recent 3W 660nm Epiled obtained from Satisled. The pattern is slightly different from the others.
Btw I wonder how efficient these are compared to Luxeon ES 660nm.
