What is the difference between LED lights and halogen lights?
2 Answers
Differences between LED lights and halogen lights: 1. Different light-emitting principles: Halogen lights use tungsten filaments to emit light; LED headlights use light-emitting diodes. 2. Different energy consumption: Halogen lights consume up to 1653W; LED lights consume around 20W. 3. Different color temperatures: Halogen lights have a color temperature of about 2700K; LED lights currently have a color temperature of 4300K or 6000K. The factory-installed halogen lights in cars can be replaced with high-quality LED lights for safer driving. However, many low-quality and unbranded LED car lights on the market have serious light scattering issues, poor illumination, and inadequate heat dissipation designs, making them prone to failure. Therefore, it is essential to be cautious when purchasing.
I've been driving for over twenty years, and the difference between LED and halogen lights mainly shows in the wallet. Halogen lights are cheap to buy, with replacements costing just a few dozen bucks, but they consume more power and have a shorter lifespan—you might need to replace them once a year. Over time, the combined cost of electricity and replacements adds up to quite a waste. LED lights are more expensive upfront, starting at around one or two hundred, but they last much longer, often five or six years without needing replacement. Their energy consumption is only a third of halogen lights, and they provide more stable illumination, making night driving less straining on the eyes. For example, since I switched to LEDs, sudden light failures have become much rarer, saving both hassle and money, especially on long trips where reliability is key.
