Radiant 400 watt HPS Grow Light

The Radiant is designed to deliver the brightest possible light down to the plants. Constructed of heavy duty pre-galvanized steel and lined with high purity European aluminum, the Radiant will provide years of dependable growing performance.

The patented double wall design and generous reflective cavity make the Radiant the coolest running fixture on the market. This double-wall reflector design runs significantly cooler than other designs - it allows placement of the light closer to plants. The Radiant reflector is air cool-able and will accept air cool fittings and a glass lens. (Fittings and glass lens are sold separately.)

The Radiant measures 21" L x 21" W x 10" T (length is apx 2" longer with socket.) Weighs 14 lbs (17 lbs with lens.)
Sturdy and Reliable
We sell this Radiant Reflector with the Lumenator ballast. The Lumenator is backed with a five-year manufacturer’s warranty. The Lumenator ballast is able to run at either 120 or 240 volts, with just the change of a cord. If you wish to run at 240 volts, order the extra cord listed below. Compatible with all Hydrofarm reflectors and most others.
