Xenon Conversion Kits
High Intensity Discharge (HID) lamps are a type of electrical lamp which produce light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina tube. There is no filament like in a normal halogen bulb.
The HID tube is filled with both gas and metal salts. The gas facilitates the arc’s initial strike. Once the arc is started, it heats and evaporates the metal salts forming a plasma, which greatly increases the intensity of light produced by the arc and reduces its power consumption. High-intensity discharge lamps are a type of arc lamp.
Compared with fluorescent and incandescent lamps, HID lamps have higher luminous efficacy since a greater proportion of their radiation is in visible light as opposed to heat. Their overall luminous efficacy is also much higher: they give a greater amount of light output per watt of electricity input.
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.
Combing low cost and a working life of between 500 and 1000 hours, halogen bulbs are the most common headlamp type in use today, although that is rapidly changing. Spurring things along is the desire of car makers to improve efficiency. Halogen bulbs draw around 55 watts of power, and much of that is wasted as it’s converted into heat rather than light.
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 UK Law 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.
In cars HID lights contain a trace amount of the inert noble gas xenon, hence their common name: xenon headlights. Xenon gas prevents automotive HID lights from flickering when they’re switched on and ensure that an adequate amount of illumination is provided before the headlights reach maximum brightness, usually within a few minutes.
Automotive HID lamps are easy to distinguish as their cool white glow is accompanied by a distinctive blue tinge around the edges. Some cars feature only HID lighting for their low beam, with high beam provided by a separate set of halogen lamps. Bi-xenon setups, however, are able to provide both high and low beam from the same set of HID lights.
HID headlights first became available in the mid-1990s, but are now optional on most mainstream models. The rare elements employed by an HID bulb have kept prices high, giving room for newer technologies to storm the fort.
Not only does window film have these benefits but it also keeps your car looking good! To view examples of our work and the various styles of window films please visit our gallery.
We also have a no gap top edge service available(ask for prices). Instead of trimming the top edge of your window we use point files to file the excess tint. This gives the effect of the tint being part of the glass.
