The original LED light bar, the Rigid Industries E-Series was the first projected LED light bar. Since its introduction in 2006, the E-Series light bar has set the standard in the industry through continuing advances in technology and superior engineering. Available in a wide range of lengths and configurations, Rigid Industries' flagship is the light bar of choice for everything from light truck or car applications and vehicle race teams to farming equipment and police or fire rescue vehicles. The E-Series light bar is designed to project light at extreme distances while consuming very little power. It features an extruded aluminum housing and polycarbonate lens that is sealed against the elements to provide years of trouble-free operation. Specter Optics - Rigid Industries' patented Specter optics system features 50 percentage more LED's than Rigid Industries' Hybrid optics in the same footprint and is specifically designed to cover more area. By incorporating a reflector with no facets or orange peel, the Specter optics system produces an intense, smooth beam with minimal wasted light. Hyperspot 5 degree ultra-narrow concentrated spot beam pattern for long distance applications. Patent pending aperture system blocks unused light for a clean beam. Highest intensity per watt or square inch on the market as well as maximum distance quality construction, Rigid Industries' circuitry is designed in-house to be more powerful, be more efficient, and generate less heat. Rigid Industries' durable aluminum housings feature custom, over-sized heat sinks which keep the temperature down and allow Rigid Industries' LED's to run cooler and brighter. Rigid Industries LED lights are engineered to withstand whatever you, the road, or nature can throw at them. Specifications: Watts: 150, Ampere Draw: 9.57, LED's: 48, Raw Lumens: 34848, Lux at 10m: 4220, Beam Distance: 1299m, Peak Beam Intensity: 422000 cd.
