Free Pair of Adjustable Hangers Included!

A Great 400 Watt HPS Replacement.

Featuring 4 Citizen CLU048 COBs this light will give you results similar to a 400 Watt HPS using only 230 Watts at the wall! The CX-4 is extremely efficient with great light intensity and low heat output.


The "sun like" light (3000k) will produce healthy vegetative growth and robust flowering without inducing excessive heat into your grow space.

Even Light Spread

The CX-4 will fill a 3 X 3 grow space edge to edge thanks to the 4 light sources in the fixture. Canopy penetration is also excellent due to the proprietary lens used in each of the 4 COBs. This will insure an even light that is easily absorbed by the plants well into the canopy. 

From Seedling to Harvest the CX-4 Will Do It All!
