Halogen lamp, the lowest cost, the most widely used, domestic models are basically used halogen lamp. The biggest drawback of this kind of lamp is not bright enough, many drivers call it “candle lamp”, in addition, the halogen lamp has a short service life, working at a higher temperature, more prone to failure.
LED lamps have only become popular in the past two years, but due to the high cost, the popularity of LED lamps is far less than halogen lamps. The advantages of this kind of headlamps are low energy consumption, long life and fast lighting speed. Leds are not only much brighter than halogen lamps, but also use 1/20 less energy.
When used in cars, the advantages of LED lights to save electricity are difficult to reflect, or difficult to quantify, even if it can be quantified, it is very difficult to make the owners in the end benefit in saving electricity; LED lamp has a long life, provided that high-quality LED lamp, poor LED lamp life is not longer than halogen lamp, but low-cost LED lamp flooded the market, it is difficult for owners to identify the quality of LED lamp, ordinary halogen lamp is also difficult to form an advantage in life.
The color temperature of halogen lamp is yellow and warm, and the light penetration is stronger in foggy days, which is relatively safer. The effect of ordinary white LED is poor, while the penetration of yellow LED lamp is close, but the light efficiency is low, and the popularity is not much.
The two kinds of lamp purchase cost is nearly 10 times the difference, another main reason, the replacement of headlights is more professional work, involving the disassembly of headlights, installation and replacement cost money, this is also one of the main reasons that halogen lamp to LED lamp is not so popular.
