The Baja Designs OnX LED light bar is 8" long and puts out 3600 lumens of light in a high speed spot beam spread. The Baja Designs OnX light bars features a copper core board which offers the best thermal management and allows these OnX LED light bars to be driven harder than any other LED light bar on the market. Driving the LEDs with more power allows Baja Designs to get the more light in a smaller package. You can have more light without having to add the extra weight of all of extra light fixtures. These lights are extremely versatile and offer you the ability to change your lenses on the fly. Four simple Allen head screws allows you to change your light from a spot, to a flood, or to a combo/driving light. The Spot beam pattern allows for a longer distance beam without affecting the clarity. Baja Designs OnX lights come with a limited lifetime warranty and will last over 25,000 hours.
