HID startup II

Starting and warmup of a Philips 35 watt D2R Automotive Xenon-Metal Halide HID lamp with the reflector removed. This type of lamp is commonly used for headlights in luxury vehicles such as Mercedes, BMW, or Lexus. Automotive Metal Halide lamps are commonly called "xenon lamps" due to the presence of xenon gas used to fill the arc tube. The xenon gas allows these lamps to provide a minimally adequate amount of light upon startup. If this lamp was filled with argon instead as is commonly done in street lamps or other stationary HID lamps; it would take several minutes for it to reach full brightness vs 30 seconds.

Headlight Comparison : Laser v LED v HID Xenon v Halogen
It wasn’t that long ago that headlights were a no-thought-required feature. All cars had them and no one really paid them much heed unless they failed or were shaped in a particularly ugly manner. Halogen Reliably generating light with the limited resources at a car’s disposal was a problem for early automotive engineers. Tungsten filaments, similar to the kind found in household incandescent light bulbs, were finally settled on as the solution. From the mid-1960s until now these tungsten filaments have been encased in a bubble of halogen gas in order to improve performance and longevity. For much of their history, tungsten and halogen lamps focused light on the road via a lens that doubled as the headlight’s protective housing; now the two jobs are separate. High intensity discharge In high intensity discharge (HID) headlights, such as those used across the Lexus IS range, a mixture of rare metals and gases are heated to produce a bright white glow. HIDs are around two to three times brighter than halogen lamps and their glare can be particularly annoying for other road users. As such, the Australian Design Rules require cars equipped with HIDs to also have a self-levelling mechanism and a headlight washer. The former ensures that the headlights are always aimed towards the ground. The latter minimises the build up of dirt and grime, both of which can divert more light into the eyes of on-coming drivers. Despite their brighter output, HID lamps require less power to operate. They generally draw about 35 watts and are said to be good for around 2000 hours of use. LED Light emitting diodes (LEDs) have come a long way from the simple flashing lights on beige computer cases to being key components in modern cars, phones and televisions. Whether you realise it or not, they provide most of the lighting used in today’s instrument panels, entertainment head units and car interiors. As well, arrays of these diodes are employed in fog lamps, indicators and brake lights. Car designers love LEDs because their small size allows them to be fashioned into ever thinner and more distinctive shapes. Although LED headlights currently fall a little short of the brightness achieved by HIDs, they hit maximum brightness within a millionth of a second compared with the half second required by incandescent and halogen lights. Laser In the Audi R8 LMX, laser beam is used only as a supplement to the existing LED headlights, activating only when automatic high-beam is being used with the aim to double the range of light compared with LED high-beam – to a full 500 metres. So, how does it work? Where many light-emitting diodes (LED) are used within a regular headlight assembly, lasers work in a different fashion. In the R8 LMX there are only four laser diodes each with a diameter of 300 micrometres, or just 0.3 millimeters – talk about tiny! They are wrapped tightly in what Audi calls a “radiation-tight aluminium module.” Rather than pointing out towards the road like a normal beam, however, they instead are directed in a V-shape to a single point on a mirror, each strand of laser producing a wavelength of 450 nanometers. ------------------------------------------------------------- http://CarAdvice.com.au is focused on getting people into the right car for them.

35w VS 55w HID color effect difference
This video shows you what happens when you use difference ballasts. Most people don't understand why some HIDs show a different color with the same temp bulb. Usually when you use a high wattage ballast, the color washes off towards a lower temperature. The higher the wattage the lower the temperature color will show. Most people will say to just change the bulb temperature if you want a different color which IS true if you stay with the same ballast. Now if you change the ballast then that is where it will get complicated. Video Description: 1st Demonstration - The 55w ballast with 6000k bulb will look like the 35w with a 5000k. Both are white. 2nd Demonstration- 55w with the 5000k will look more the the yellowish white color of a OEM HID system and/or of a OEM halogen bulb. And the 35w with the 6000k will have a white color with some tint of blue. *****FOR MOBILE VIEWERS***** 10/5/2012 I've noticed none of the Annotations can't be seen on a mobile device. I guess the YouTube app doesn't support it. It may not make a big difference but I just figured I'd let you know It can be a bit useful to see them especially at the end of the video and my spelling errors LOL ;) Thanks for watching
