The world’s first 7-inch round 12-volt LED headlamp from Truck-Lite is said to offer the extended life and energy efficiency of light-emitting-diode technology, as well as brighter, crisper and whiter light output than incandescent alternatives with lower power consumption. The lamps have solid-state circuit board assemblies for shock and vibration resistance and hard-coated polycarbonate lenses that are claimed to offer 30 times more impact strength than glass. They are essentially, says Truck-Lite, maintenance-free.
The new LED headlamps are designed to replace any standard 7-inch round headlight within 12-volt applications. They can be aimed using standard mechanical aiming equipment, and they meet or exceed all applicable DOT requirements.
Made in the U.S. each headlamp uses 10 high-output LEDs as its light source, with an output said to be brighter than traditional glass beam headlights, which results in better visibility. While a typical headlamp may be rated to last as little as 1200 hours, Truck-Lite says these LED lights are expected to exceed that by as much as 50 times. It’s claimed they’ll offer improved visibility over conventional incandescent lamps, as the color temperature of the assembly is around 5000K, far closer to sunlight than incandescent or halogen lamps.
The U.S. military has acquired more than 100,000 of these headlamps in 24-volt form since their release in 2007 for use on both new and existing wheeled and tracked vehicles in Iraq and Afghanistan. After rigorous testing and design improvements through both laboratory and field studies, the 24-volt lamp is currently active on a number of military vehicles.
