HID Lighting is a Viable Alternative to a Halogen Bulb

HID or high intensity discharge lighting (also known as Xenon lighting) replaces the filament of a light bulb with a capsule of gas. The light is emitted by an arc discharge between two closely spaced electrodes, hermetically sealed in a tubular quartz capsule. It requires ballasts (which supply proper voltage and control current), in order to operate.

This kind of lighting produces only 5% of its out put when first ignited, it requires a few seconds(about 15 to 20) to come up to its full out put. It has several advantages over conventional halogen lights. The amount of light produced by it is much greater than a halogen light. The light produced is whiter in color(it more closely approximates the color temperature of natural daylight) than a halogen light which appears yellowish in color. It has a longer life and on an average lasts three to five times as long as a halogen bulb. Also the power consumption is much lower as compared to a halogen bulb.

Although this light does not produce as much heat as a halogen bulb, yet care must be taken while handling it. It should not be left for too long in sunlight, and care must be taken that the temperature of its immediate surroundings is not too high. Both the bulb and the ballasts are sensitive to external operating temperature. It should also be kept in mind that this lighting device contains metals including mercury which are harmful to the environment. Proper care must be taken to ensure its safe and secure disposal.

The white light produced by this device, provides optimal illumination for driving, enabling the driver to see more clearly. The longer burn time and the sun light quality color temperature also make it an ideal choice for underwater videography, photography and exploration.
