4 COB 3,125 micro mole, 400 watt LED Grow Light
Reliable Full Spectrum Grow Light
This high intensity four Cree COB LED Grow Light is best in 4x4 tents. We think that is is the best COB LED Grow Light on the market today. Plants need full spectrum light, and this light delivers across the PAR range. Upgrade to COB LEDs for maximum growth and save 15% plus a free trucker cap.
Better light = better plants!
It is an excellent choice for home or farm growers who desire full spectrum light over a larger area for a multiple plants or multiple trays of seedlings and clones in early stage growth. This unit has a dimmer switch which provides control over the light output to suit either vegetative growth or flowering stages. This light may be daisy-chained.
An excellent application for this light is a 4x4 grow tent growing clones to maturity.
Please note that we sell lights to the U.S. market only.
The four COB LEDs produce the full spectrum of light from 380 nm to 780 nm. The BF3590.4 produces 48,000 Lumens using around 400 watts of electricity. At a height of 8 inches above the plants, the BF3590.4 delivers 98,660LUX or 3,125 micromoles directly beneath the light.
See Learn About Light for more details on full spectrum testing results and lighting parameters.
See How to Plan Indoor Lighting for planning guidance.
Position the BF3590.4 over the plants to achieve the desired results:
Here is a very simple comparison: the BF3590.4 delivers as much light as 39 100 watt light bulbs! And, at only 15% of the three year cost of those lights!
Safety: Do not look directly into the Cree COB LED. Small amounts of UV / IR wave lengths are produced as well as very bright visible spectrum light. Cree classifies the CXB3590 COB LED as RG-1 (low risk). We recommend using UVA/ UVB rated sunglasses under high intensity lighting.
Please note that this is an electrical device. It is not waterproof or water resistant. We strongly recommend plugging the BF3590.1 into a standard household GFI (Ground Fault Interrupter) electrical outlet. GFI outlets are now standard in kitchen, bath, and workshop electrical applications.
This unit is assembled in China with globally sourced parts. The Cree COB LEDs are designed in the US and fabricated in China to Cree specifications.
