The Brilliant H1 LED: Composed of top-notch ETI chipsets, luminous efficiency up to 20,000 LM/pair (10,000 LM/bulb). The H1 LED is in the original adapter, which is not compatible with the required special car adapters. Please check your adapter before purchasing. Highest Power: 200W per pair (100W/bulb), high performance, much higher than other brands. H1 LED headlights have almost the same power as traditional halogen bulbs, but 3 times higher brightness and 5 times greater lighting distance than old incandescent bulbs. High-tech cooling system: two-way heat dissipation, aviation aluminum housing quickly dissipates the heat generated by LED chips. The quiet high-speed fan provides a strong cooling wind to accelerate heat dissipation into the air, making the cooling efficiency 100% higher than traditional LED lamps. Ensures a service life of more than 55,000 hours. Perfect light model: 1:1 same light position as halogen lamps guarantees a perfect light beam at low/high temperatures
