There are two beam patterns offered, a wide beam and a focused beam. The lights are available in 10 inch increments up to 50 inches long. A six inch light is also available. The lights are 3 inches tall which provides for a great form factor and easy integration for grilles, bumpers, rooftops & roll cages. Our housing is designed to extract heat very efficiently so the lights are cool to the touch. This makes adjusting while the light is on bearable. Also, the housing is aluminum which provides for a very lightweight but strong casing. Each ten-inch segment weighs 3 LBS. Each ten-inch segment is 38 watts with a 3.3 amp draw at 12 volts. LEDs are also the answer to off-road lighting due to their construction. The LEDs are mounted to a surface and are not subject to vibration as are typical bulb assemblies. We have also eliminated any external ballast. All electronics are internal making the installation easy with only two wires to hook up.
