First, the high color temperature of HID lamp life is short, 4300K lamp life of 3200 hours, 5100K and 6000K lamps is about 2000 hours, but the lamp color temperature up to 10000K, life has found no information (because the light pipe manufacturer does not provide), but the estimate based on the data front, it should be only the standard product life 1 / 2 (10000K bulb of the internal pressure due to high).
Halogen bulbs in a general example, the illumination is about 1450Lm (lumens), 4300K bulbs 3200Lm, 5100K bulbs 2700Lm, 6000k bulbs about 2500Lm, but the 10000K bulb illumination is almost the only 2000Lm around than a full 4300K light bulbs as much as 40% less!
In addition to bright enough, the penetration is a problem. Human eye in visible light wavelength of about 380nm (violet) ~ 770nm (red), between the shorter the wavelength of light penetration, the worse it, the more difficult to penetrate the water vapor or mist, but prone to the phenomenon of refraction! Previous "ultra-white light bulb" will appear in the rainy nights "There did not seem to turn on the lights turn on the lights," the situation is for this reason, because the light is reflected off the surface to the water.
Replacement of the higher color temperature HID, lighting ability in the rainy day worse! So, if double-B and other manufacturers, they still insist on using 4300K (or 5100K, it has been with the United States through the European E Mark certified SAE) of HID bulb to accommodate a variety of different lighting environments (snow, the rain, etc. ) because that is the case.
HID, halogen lamps with different
Reflector headlight design, there are two, one is the MR surface, a curved line is the thing. The former takes the shape of the diamond-shaped reflector, the use of different angles of each piece, the light reflected to the ground, one after another broad re-lighting area. The property line of the light parallel to the surface will be sent to all the light shell, lamp shell re-use pattern to shoot the light curve, the average illumination purposes. HID light bulb because the higher point (higher than halogen bulbs 0.5mm), so (light type) and halogen bulbs, or light, whether the diamond surface must be re-designed shell patterns, but as long as the tube axis positioning enough accurate, beam headlight glare can still be, the phenomenon of scattering to an acceptable range.
