I bought both the 3000k and 4000k model of this same 100w light. I'm not a professional grower of anything, so take my words with a grain of salt. This light is quite efficient, it's passive heatsinks get moderately hot/warm but not uncomfortable to the touch with ambient room temperatures of 70 - 75, not bad considering how still the air is (I should probably get a fan in general for better air circulation for my peppers and cactus plants). The color of the 4000k and 3000k lights are both quite white, but the 3000k has a notably warmer hue (still far closer to white than the orange glow of an HPS). I'll update my review later if I can think of more useful information to include. The only thing I wish these lights came with would be a lens for the storing the LEDs without worrying about damaging them.

We start with our 100 Watt Cree CXB3590 Kit. Then we add an aluminum angle frame. Then we mount everything to the frame with the appropriate spacing matched to the size of your growing area. All you do is hang it up and plug it in.
Using selected components considered by many to be the best combination of efficiency and light quality, we offer a 100 watt CREE CXB3590 COB Linear Frame Grow Light with (2) Cree CXB3590 LEDs pre-assembled and mounted on highly efficient Cooliance black anodized aluminum pin cushion heatsinks using Arctic 5 Thermal paste - wired up to a Meanwell HLG-185H-C1400B power supply with waterproof quick connectors and a pre-wired potentiometer for dimming. Fused 10A power cord and 18GA wire keep things safe. This power supply can power up to (4) COBs @ 50 watts each for future planning.
This light comes completely assembled as shown. Get up and growing fast and safely. Our frame is designed to spread the light output evenly over your grow area to give even coverage at operating heights of 12-18" above the canopy.
