What is the appropriate wattage and lumens for LED car lights?
2 Answers
Automotive LED lights with 35W have a lumen output of 3200, which is 91 lumens per watt. Generally, 80-100 lumens per watt is the most suitable. Below is some relevant information about automotive LED lights: 1. Meaning of LED lights: LED stands for Light Emitting Diode, which is an electronic light-emitting device. It uses a solid-state semiconductor chip as the light-emitting material, and light is emitted directly through the recombination of carriers causing photon emission. 2. Advantages of LED headlights: High brightness, typically 4-6 times brighter than original halogen bulbs; very low temperature, usually between 50-70 degrees Celsius. Due to the low temperature, performance is very stable with almost no light decay, instant start-up with no delay, and very uniform light distribution on the road.
I've been driving for ten years and often drive at night, so choosing the right LED headlights is crucial. Generally, a power rating between 15 to 20 watts is sufficient—anything higher might cause overheating and waste electricity. In terms of brightness, 2000 to 2500 lumens is the sweet spot, providing enough visibility at night without blinding other drivers. Keep in mind that factory-installed lights usually have lower brightness, so consider weather conditions like rain or fog when upgrading. I've tried Philips bulbs with 2000 lumens, and they work perfectly. Avoid products with exaggerated specifications—always check the specs for accuracy, as safety comes first.
