Each Intensity light weighs close to 7 pounds, so a TIG-welded 304-grade stainless-steel mounting system was designed so that it can also be flipped to hold the lights parallel against a vertical surface (like on the back of a utility bed). It uses two bolts per side to hold the light in place—the larger bolt to carry the weight of the light and the smaller bolt to hold the angle of the light. The body of the light is actually designed to be a large heat sink with cooling fins in the back that increase cooling surface area by 200 percent. While surface-mount LEDs (light-emitting diodes) themselves do not produce much heat, the circuitry and parts that power them do. This heat needs to be dissipated.
