What is the ideal wattage for car LED headlights?
1 Answers
Generally, LED headlights for cars range between 30-40W, while daytime running lights should not exceed 10W. However, the specific wattage depends on the original headlight power and personal brightness requirements. Theoretically, higher wattage LED headlights, meaning greater power, result in brighter illumination. But in practice, higher wattage isn't always better. Increased wattage leads to higher power consumption and operating temperatures, demanding better heat dissipation. Here are some additional details: 1. LED chip temperature: The operating temperature of LED chips must be kept below 85°C to ensure a lifespan exceeding 30,000 hours. Higher wattage LEDs generate more power and heat; exceeding 85°C will shorten the LED's lifespan as temperatures rise. Additionally, since car electrical systems have rated power limits, excessively high-wattage LED headlights can overload wiring, causing overheating and potential damage. In terms of luminous efficiency, LED headlights of the same wattage are brighter than original halogen bulbs. 2. LED light power: LED lights are categorized into different power ranges based on energy consumption, typically including 10W, 20W, 30W, 50W, and 100W for single automotive units. For reference, a 1W household LED bulb is equivalent to about an 8W incandescent bulb, while automotive LED lights are 2-3 times more powerful than standard halogen bulbs. Therefore, when replacing bulbs, it's unnecessary to choose higher wattage options; stick to LED lights with the same or lower power ratings as the original bulbs.
