The light ouput is about 85% usable by the plant as compared to about 15-20% (?) for HPS.

Notice the full red spectrum from orange and on into far red with very little wastage in the yellow and green and a nice bump on the low frequencies which includes blue, royal blue and cyan. The light appears pink/lavender to human eyes.

Unit size is roughly 8" deep * 24" * 15" and weighs 22-25 pounds.

Initial studies in Chinese Universities look promising and I have requested the papers, but we all know that we need experienced growers stateside with well-documented grows on our favorite plant to do a real-world proof of concept.

I like the fact that this is a new application, but a well-proven technology in commercial lighting. The phosphor coating specifically designed for plants is mainly what is proprietary.

The rectangle with the U-Bend tube in the lower right attachment is what the output looks like.
