Description and Overview 

Radiant 2000 AKA “The Quad” is the most powerful light yet from ALT. It incorporates the same 100 LED diode chip technology as the Radiant 500 made-usa-ul but at four times the strength. Each fixture is designed for a 4 x 4 (16 sq ft) growing area. It has been developed for commercial grow facilities and serious horticultural and agricultural enthusiasts.

ALT’s Radiant Series lighting delivers the highest Photosynthetic Active Radiation (PAR) in the industry. More photons delivered to the target creates the maximum stimulation of the Krebs Cycle and an increase in ATP Synthase to accelerate photosynthesis. The result is a better performing LED grow light.

The Radiant 2000 is a 515 watt LED lighting powerhouse, designed for all of your indoor agricultural needs. The unique spectrum formula of LED diodes, combined with our patent pending integrated power chip design, is the most effective and efficient grow light available. The Radiant 2000 is used to grow plants that produce hearty and abundant medicinal flowers, as well as organic fruits, tomatoes, peppers, leafy greens, and herbs.

The Radiant 2000 is UL listed and rated IP 55, suitable for wet and damp locations. Our unique formulation and spectrum allows the grower to use a single light for the full grow cycle from Veg to Flower.
