Shat-R-Shield has added a 280W, 30,500 lumen option for ceiling heights above 30 feet. At 109 lumens per watt, the fixture consumes approximately 40 percent less energy with triple the life hours of its 450W metal halide lamp counterpart. The industrial LED provides instant on/off, no threat of glass or arc tube rupture, and reduced heat output in comparison to antiquated light sources. The choice of prismatic or aluminum reflectors with optional lens cover helps to control beam spread for omnidirectional light output or for more concentrated distribution. The LED boasts a lifetime of L70, greater than 55,000 hours and projected L71 of 224,000 hours, backed by a seven-year limited warranty. Other enhancements include 0-10V dimming and options of 120 to 277V or 347 to 480V drivers.
