What is the appropriate lumen for car LED headlights?

[SanMelanie]

Generally, 80-100 lumens per watt is the most suitable, but it depends on the original headlight power and personal brightness requirements. Here are specific details about car LED lights: 1. A 35W car LED light has 3200 lumens, which is 91 lumens per watt. 2. Theoretically, higher wattage LED car lights, meaning greater power, result in brighter illumination. However, in practice, higher wattage is not always better. If the wattage is too high, the increased power leads to higher operating temperatures, requiring better heat dissipation. 3. The operating temperature of the LED chip must be kept below 85°C to ensure a lifespan of over 30,000 hours. 4. Since car circuits have a rated power, if the LED light wattage is too high and exceeds the load capacity of the car's wiring, the wires may overheat and even burn out. In terms of luminous efficiency, LED headlights of the same wattage are brighter than the original halogen bulbs.
