#Led vs halogen drivers#

Another reason is that LED headlight bulbs allow being designed freely to cater to the appetite of customers. They convert 90% of energy into light and less heat wasted, thus they are more energy-saving than halogen bulbs.

By keeping the LED bulbs working at a reasonable temperature, they can promise to last a long lifespan of at least 30,000 hours.īesides LED headlights are favored by many drivers for the main reason that they illuminate stronger and brighter light with less energy consumption. It is the latest lighting technology and quickly gained popularity in the automotive lighting market.Īlthough LED headlights generate heat when lighting, they are equipped with an extra heat sink and high-speed fan for better heat dissipation. To make it simple, LED (Light-emitting diodes) headlight uses semi-conductor (or diodes) to transmit energy-emitting photons to give off light. They are favored by automotive manufacturers as the cost of halogen bulbs is lower than LEDs and they are easy to be replaced. Mostly, halogen bulbs used in automotive lighting normally emit a yellowish light.Ībout 90% of vehicles leaving from the factory are equipped with halogen bulbs. Halogen lights produce an average brightness of 700 lumens in low beam and 1200 lumen in high beam which is brighter than incandescent bulbs but they are far less than LED bulbs.

The halogen gas makes the temperature of the filament raised gradually until it almost reaches the melting point of tungsten (3400 degrees).Īs mentioned above, halogen headlights are less energy efficient than LED headlight bulbs as most of the energy is wasted in heat instead of light. They give out the light when electricity passed, then the filament glows and tungsten will be evaporated. Halogens are different from regular incandescent bulbs as they include a thin tungsten filament surrounded by halogen gas in a glass capsule. Let us move on to have a deeper understanding of the differences between LED and halogen headlight bulbs. For these reasons, LED headlight bulbs have been the No.1 choice for some new non-luxury cars. To get a comprehensive grasp contrast between LED and halogen headlights, we had better understand the different characteristics between these two lamps.įrom the chart above, halogen headlights are outweighed by LED headlamps in many aspects as we can see: compared to halogen headlights, LED lights are brighter, more energy-efficient, have less heat emission, and a longer lifespan.Ĭonsidering long-term night driving, LED headlight bulbs are much better than halogen bulbs.
