Bi-xenon lamp: 1.High brightness:both its luminous flux and luminous area are 3 times as that of halogen lamp. 2.Long life time:the lifetime is more than 3000 hours, that is around 10times of the halogen lamp. Low power consumption: only half of the amount that of the halogen lamp. 3.High color temperature: (the most for halogen is only 3000k)4000k to 12000k(the higher the color temperature the color will turn to be a little bit blue) 4.Safer: h.I.D xenon lamp provides you with a more comfortable, wider, bright and farther visual scope. 5.Catalogue: lamp type: d2s, h1, h3, h7, 9005, 9006, 9007, h4(b1-xenon), h4(flexible), h4(near xenon, far halogen) 6.Color temperature: 3000k-12000k 7.Ballast technical parameter: input: dc nom 8-18v output: 35w 8.Working temperature:-40c---105c 9.Lifetime: above 3000hr 10.H.I.D bulbs specifications: normal 11.Input voltage: dc 12.8v 12.Allowable input voltage: dc9v-18v 13.Normal input current: 3.5a 14.Normal output wattage: 35w 15.Rapid start-up: reach 80% of full luminance within 4 sec; start-up with low voltage; quickly launching protection device when short circuit happened White packing, oem packing or neutral packing, according to customer
