1. Lower Energy Consumption: D2S hid bulb use only 35W of power, about half that of a 65watt halogen bulb, a 40% reduction in electricity consumption. The highpurity xenon gas is electronically excited and reaches its brightest state in less than 3S 2. Brightness Upgrade: D2S xenon hid bulb is up to 7600LM/set, which is 300% brighter than halogen bulb, 90% brighter than ordinary xenon bulb. High purity xenon gas obtains clearer and farther lighting, which greatly reduces the rate of traffic accidents 3. Accurate Alignment: Each D2S bulb is laseraligned to the base during the manufacturing process to ensure a tight beam pattern with no glare or black spots. The color temperature of the xenon blend is measured and will not fade over time 4. 3500HRS Lifespan: D2S is equipped with AntiUV Quartz Glass to ensure consistent light output. IP67 waterproof design and high temperature resistant metal base reduces fogging and vaporization damage caused during driving
