We start with our 300 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 300 watt CREE CXB3590 COB Square Frame Grow Light with (4) Cree CXB3590 LEDs pre-assembled and mounted on highly efficient 140mm Cooliance black anodized aluminum pin cushion heatsinks using Arctic 5 Thermal paste - wired up to a Meanwell HLG-320H-C2100B power supply with waterproof quick connectors and a pre-wired potentiometer for dimming.  Fused 10A power cord and 18GA wire keep things safe.  This light is designed to cover a 2.5' x 2.5' to a 3' x 3' flowering/full cycle coverage area.


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.

Light came in extremely well packaged. Installed the light at 21 inches from my canopy and it covers the whole 3x3 tent im using . After 5 hours i noticed my leaves were buring(curling) so i moved the light to 25inches and lowered the power to 70-80% and my plants are happy again. I look forward to seeing what this light can do. It is very powerfull and well built. Its ready to go once you unwrap the packaging. Thank you timber growlights! I think rhis will be the best out of the 4 different leds i use.
