600 watt full spectrum LED grow light

Quote:

I just want about 100 watts of high quality red 660nm diodes for lighting up the under- canopy.

4-LEDengin 15w 660 deep reds ~ $125
1-Mean Well PLN60-12 led driver ~ $ 55

Plus whatever heatsink / fan option you like. (anywhere from free to $50).

Easy to do, we'll help ya. That's ~50 watts (to the leds) of top-notch bloom power. You need so little blue light (for flowering cannabis) that a small T5 or a 6500K CFL, pretty much anything, will provide it. That combo should give close to the results of a 150W HPS.

You didn't want that HGL kit anyway. His specs are honest; they clearly state the lamp sends a mere 8 watts to the leds (only draws 10W). That'll give you the photon power of ~16 watts of HID. Hardly significant, especially considering the fact that hi-power leds will cause leaf bleaching and light avoidance at 2-6" away, and will cause thermal burns if you let the foliage rest against them. These are NOT like the 225-emitter panels that the plants had to touch to notice an effect. You won't be able to squeeze good leds into tight spots between plants any better than you can with, say, CFLs (which is what I use if I need some upskirt lumens).

Google "nasa lightsicle" and read the "tech" papers and follow the links. Get on the NASA website and use their search engine and search "intracanopy" and other relevant terms and read for yourself what (little) actual research was done, and how unimpressive actual test results turned out to be. Also note that the lightsicle design was not so much to provide intracanopy lighting, as to develop a convertible configuration light engine ( starts out vertical, ends up overhead) to accommodate an automated system for all stages of plant growth.

The NASA plan was/is to light mature plants from the top only, despite various sales pitches to the contrary.
