After finally getting some in at the shop, I got to play around with the Purple and Magenta models. They are very small, but manage to put out a lot of light. I'm adding them to the 3K and 10K MH lights in the flowering room. The price is still expensive, but it looks like small powerful LED lights for plant growth is finally here. They have also released a blue light for vegetative growth and a pure red light for bloom boosting. I'm not putting away the HID lights any time soon, but these are really nice for supplemental light in the flowering room. I imagine these lights are going to really come in handy for all you cats doing that stealth deal. Kessil Lighting- The Spectral Revolution They retail for around $350 a pop. Kessil Lighting- The Spectral Revolution I will, in the near future, be doing some experimental grows using these lights only. Things are really busy for me, so I don't know when I'll get to it, but now that we have these lights in stock, I'm gonna do some playing. If anyone has experience with these, chime in.
