Been scouring the net for Cree 3 Watt deep reds ~660nm without much luck. I don't think Cree has a 660 in their current high end line-up, or my Google-Fu failed.
I am only familiar with Cree, but am up for any quality 3 Watt ~660 chip.
I am not to keen on the China LED panels, due to cost, shipping, quality concern, and not being fully tested. And I would like to try my hand at an LED build.
