Our 1:9 Hydroponic LED Kit is based on the 95CRI Cree CXA2530 LED. This LED is as close to natural sunlight as it gets. We specifically Bin these LEDs at 3K 95 CRI. Other versions of the Cree CXA2530 simply do not replicate natural sunlight as well. To this we added 3 Cree XT-E Royal Blue, 3 Cree XP-E2 Blue and 3 Cree XP-E2 Photo Red to optimize photosynthesis. Thus 1:9. At only 75 Watts this rivals many Metal Halide Lamps and is perfect for a single Pepper, Tomato or other plant. With virtually no heat this is perfect for any indoor garden including Grow Tents.
