Colorlight searchlights use a dual-light head platform that can be configured with dual light beams for half or full power, and built-in redundancy should a bulb fail. They also offer two different light sources: LED to reduce power consumption and ultraviolet for poor visibility conditions. The searchlights feature unlimited vertical and horizontal maneuverability and are housed in IP66 acid-proof stainless steel for protection from the elements. The lights can be mounted either upright or inverted, and feature sweep, surveillance, and fixed-position automatic-control options.
