How many watts is the best led car light, car led light wattage comparison table

Generally, LED headlights are 30-40W, and daytime running lights are no more than 10W, but the specific requirements should be based on the original car light power and personal brightness requirements. In theory, the higher the wattage of the led car light, that is, the higher the power, the brighter the brightness. But in fact, the higher the wattage of LED lights, the better. If the wattage is higher, the power will be greater and the working temperature will be higher, which requires better heat dissipation.

Because the working temperature of the led chip must be controlled below 85°C, so as to ensure its service life can reach more than 30,000 hours. If the wattage of the led is high, its power will be high, and the working temperature will also become higher. Once it exceeds 85°C, the life of the led lamp will be shortened as the temperature rises. In addition, because the car circuit has a rated power, if the wattage of the LED lamp is higher and exceeds the load of the car wire, the circuit will heat up, and it will even cause burnout. In terms of luminous efficiency, the brightness of LED headlights of the same wattage is brighter than that of the original car halogen lights.

According to power consumption, led lights can be divided into different power ranges. Generally, a single car has 10, 20, 30, 50, 100 watts, etc., and a 1W led light for home is equivalent to an incandescent lamp of about 8W, while a car led light The power is 2-3 times that of ordinary halogen lamps. Therefore, when changing the lamp, there is no need to change a higher-power bulb, only the same power or lower power LED lamp as the original car.
