I was asked and volunteered to evaluate a new LED plant light. It is the Grow Master LGM-5, the company's newest model.
Well it arrived today, of course the first thing I noticed was the addition of a few yellow LED's and one green LED to each of the 5 clusters (notice in the second pic that the center is white). My spectroscope doesn't like the small concentrated energy source so I will have to modify it a little to get a clear reading of specific wavelengths. Initially it appears to have broad spectral performance in all the desired ranges with *most of the energy in the red and blue portions (*going by number of LED's)
It definitely hurts to look directly at it, listen to the caution notes and don't do it LOL...trust me it will give ya a headache
I'm not sure yet of how exactly I am going to test the performance... the light only arrived today,
but I will keep ya posted
The advertised foot print is 1' by 2' and the recommended distance above the plant is 18"-28"
(FYI, the lights were still on in the room when the second pic was taken, my point and click camera tried to correct for the brightness LOL)
this is going to be fun, and thanks to DaveS for asking me to evaluate their newest model, I am deeply honored
