The new "E" Series High Intensity L.E.D. Light by Rigid Industries. General Specs: 93% Optical Efficiency Shockproof No Vibration 80 LED's with 50,000+ Hour Life Span Easy Two Wire Installation 14.44Amps 195 watts 18000 Lumens Patented Hybrid Technology runs lights at 90% efficiency which is unmatched in the industry. 8" of flood reflectors on the outsides of the light and 32" of spot reflectors on the inside half of the light. This will optimize both functional light spread and light distance for increased visability. Dimensions: 3.375" High 3.625" Deep 41 3/8" Long Why LED? A light-emitting-diode (LED) is a semiconductor diode that emits light when an electrical current is applied in the forward direction of the device, as in the simple LED circut. The effect is a form of electroluminescence where incoherent and narow-spectrum light is emitted from the P-N junction in a solid state material. Advantages of LED lighting: 50,000 hour life expectancy Very High Lumens per Watt No glass lens to break No Bulbs to Burn out No Ballast to Mount Rigid Industries Advantage,it's all in the reflector. Patented Super Efficient Reflector 93% efficient vs. 72% "Brand X" reflectors Available in both Pencil and Flood Beam More Light with Less Power, Heat and size. Much Father Projection Multi Source Light No "bouncing" beams Virtually eliminates HID vibration If one LED fails the other LEDs will not Greatly Reduces eye fatigue
