hey kids…I use the Cree XR-E 7090 XLamps in grow lights. I’ve found the best prices in small volumes to be from a company called LEDlightingsupply. Generally I pay $3 a Cree for the 2W ones.
I know very little about LED’s, how the brain reacts to different light waves or different flashing frequencies, but I’m curious. You use Red, Blue and Green LED’s, but why not use white LED’s?

I can’t wait until the rest of the solar sail is done. Not sure if you’re going to get enough photo pressure from this light though.

Well, that’s one way to get people to quit tailgating.
