Weighing only 8 pounds, the interior of the Lumen Max is a combination of smooth and textured 95% reflective German aluminum to give maximum light reflection. Exterior construction is corrosion resistant, light weight aluminum - no need to worry about rust from your garden's high humidity levels. 

The square design of the Lumen Max provides astoundingly uniform light dispersion and is ideally shaped for a 4' x 4' growing area. Comes with integrated mounting bracket and hanging hooks. As is cannot hold a glass lens to handle heat venting / air cooling, the Lumex Max is better suited for cooler climates during the summer months.

Sun System Lumen Max reflector dimensions: 22.25" Long x 22.25" Wide x 8.75" High
Weight: 8 lbs
