What is the appropriate lumen for car LED headlights?
1 Answers
Currently, there are three types of car headlights commonly used, listed in the order of their introduction: The first is the original halogen bulb, with a 55W halogen lamp producing 1000 lumens. Even though halogen technology is mature, there is little room for further improvement in brightness. The second type is the xenon lamp, with a 35W xenon lamp producing 3500 lumens, achieving 100 lumens per watt. The third type is the LED headlight, with a 35W LED lamp producing 3200 lumens, achieving 91 lumens per watt. Additional information: Xenon lamps are categorized into 120V, 240V, and 380V, with wattages ranging from tens to thousands of watts. Automotive xenon lamps are improved versions of industrial xenon lamps, operating at 12V with wattages of 35W and 55W. Most vehicles use 35W lamps, while a few use 55W lamps, which are mostly installed on high beams. Therefore, the lumen range is 3500-5500. Headlights, commonly known as "big lights," are installed on both sides of the front of the car to illuminate the road ahead. They can be configured as two-lamp or four-lamp systems. In a four-lamp system, the outer pair is typically dual-beam lamps for low and high beams, while the inner pair is single-beam lamps for high beams. High beams range from 35–60W with 3400-5900 lumens, and low beams range from 35–55W with 3400-5400 lumens.
