LED headlights generate light through electrical current. The conversion from electrical power to optical power is close to quantum limit meaning that it is much more efficient than normal light bulb (about 80% energy saving). The part of electricity that did not convert to light dumps into heat sink of the headlight and increases temperatures.
Every high power headlight will generate heat and become hot over time. The higher the power, the more heat. Depending on the size of the light, the heat will transfer into local temperatures or hot tempratures. The smaller the light, the hotter it gets with the same amount of electrical driving current and same surface areas.
DentLight’s headlights are designed to optimize the heat at their individual design size and engineering target. There is one main difference between our lights and other competitors lights in that we isolate front end (lens housing assembly) and back end (articulating arms and loupe adapters) of the light with heat insulation materials that will never get hot for safety operations.
In the low digital power setting, the lights will never get hot. In the highest digital power setting, the heat sink will get hot but other areas with easy access to finger, nose and forehead will never get hot. So use the light according to our instruction, it is safe to operate all the times.
