It brought out the colors much more quicker and vibrant than my old lamps. It's great for the colorful strains, as long as you feed them extra magnesium (and probably calcium) especially in the flowering. Otherwise your plants might get overworked pretty quickly and lose all their luster instead. Overall; very good lamps.

When I first saw the PPFD chart, I thought it was another overpriced LED that I wouldn't have a chance to afford in years of savings :) But I decided to give it a chance when I learned that their prices aren't that high compared to the LEDs that give the same or even lower PAR outputs It is certainly a game changer. The electricity costs have been dropped to almost half of before, and the buds are ridiculously big. I always used 600W HID lamps before, and wondered how 1000W HIDs would yield, and how big the buds can get. Honestly, I can't think of bigger indoor buds. I guess this is the upper limit for indoor growing lighting and I'm really happy that I achieved it sooner than later :))
