One of the factors that 18W LED fog Light improves energy efficiency is the low heat output of the bulb. 18w work light is an important feature of these types of bulbs-they can emit brighter light than halogen bulbs without generating too much heat. LED fog lights are designed to effectively dissipate any heat they generate, thanks to the unique"heat sink"at the bottom of the bulb assembly. Even if you choose a bulb with a higher calorific value, the LED lamp can also have a small cooling fan built into the base to eliminate excess heat.
