Understanding Halcyon HID Lighting

High Intensity Discharge (HID) lighting technology replaces the filament of the light bulb with a capsule of gas. The light is emitted from an arc discharge between two closely spaced electrodes hermetically sealed inside a small quartz glass tubular envelope capsule. To operate, they require ballasts, which supply proper voltage and control current. The amount of light produced is greater than a standard halogen bulb, while consuming less power, and more closely approximating the color temperature of natural daylight.

In all High Intensity Discharge lamps, light is produced by passing a current through a metal vapor. Free electrons colliding with an atom in the vapor momentarily knock an electron into a higher orbit of the atom. When the displaced electron falls back to its former level, a quantum of radiation is emitted. The wavelength of radiation depends on the energy zone of the disturbed electron and on the type of metal vapor used in the arc tube.

Although it produces 5% of its output when first ignited, the HID light requires a few seconds (usually 15-20) to come up to full output. Also, if power to the lamp is lost or turned off, the arc tube must cool to a given temperature before the arc can be re-struck and light produced. Halcyon HID lights only require a brief (15-30 second) cooling period before they can be re-lit.
What are the advantages of Halcyon HID lights over conventional halogen primary lights?

HID lighting has several advantages over conventional halogen primary lights:

More light output. Halcyon's 18 Watt HID light source produces approximately the same lumens at the light source as a 55 Watt halogen bulb at a three to five times the halogen's efficiency. The 10 Watt HID only produces ~500 lumens, but thanks to its true 6000K color temperature it appears almost as bright as a 55 Watt halogen bulb when in use. The HID lamp's lumens per watt (LPW) efficacy is roughly six to eight times that of an incandescent lamp.

Whiter light. The color temperature of HID lighting more closely approximates the color temperature of natural daylight than does a halogen system, which appears yellowish in comparison. We use the term "correlated color temperature" to indicate that the light appears as if the discharge lamp is operating at a given color temperature-- traditional measurements of color temperature are drawn from the properties of the metal used in the bulb's filament. Typical color temperatures are 2800K (incandescent), 3000K (halogen), 4100K (cool white or SP41 fluorescent), and 5000K (daylight-simulating fluorescent colors). Both of the Halcyon HID lights produce a light with a color temperature approaching or above 5000K. A white light has a perceived brightness which may equate to the higher stated efficacies-- ie., although an HID lamp might have equivilant lumens as a higher wattage halogen bulb, the HID will appear brighter and more pleasing to the eye than the output of a halogen lamp.

Longer Service Life. An HID lamp will last, on the average, 3 to 5 times as long as a halogen bulb. In normal use, your Halcyon HID bulb should last beyond one thousand ignitions. http://danceshoes.hyperphp.com/ http://bariatric.atwebpages.com/Car%20alarms

Contemporary Lighting

The most distinctive feature of contemporary lighting is that the designs and styles adopted try to blend in to the general home dcor. The use of geometrical shapes with clean cut lines defines most contemporary light fittings. contemporary lighting is a practical approach to the lighting needs of a house. Task lighting is one of the main lighting needs attended to by contemporary lighting fixtures. Pendant lighting fixtures are the popular choice for task lighting solutions. Fixed over a particular area, pendant lights provide focused lighting for that particular area. Work desks, breakfast nooks and counter tops in kitchens are the usual places where pendant lights are used. Colored glass pendants are one of the most popular types of contemporary lighting fixtures used. contemporary lighting fixtures also incorporate the use of clear and colored crystals and finely cut glass shaped into flowers and other interesting shapes. Marbleized, frosted, gold and silver are some of the effects imparted to glass for use in varying contemporary lighting fixtures. Swarovski crystals and Murano glass are examples of some fine materials that are used to create exquisite pieces of contemporary lighting. There is an increasing awareness the world over about the proper utilization of the world?s scarce energy resources. Energy saving lamps have been introduced everywhere to minimize wastage of energy and optimize its utilization. Several contemporary lighting fixtures use energy saving lamps as their light source. People with a sense of social responsibility make conscious choices of using energy saving light sources. The availability of varied designs of contemporary lighting fixtures ensures that such people do not have to compromise on looks as a result of opting for energy saving light sources. Recessed lighting, pendant lighting, track lighting, wall sconces, portable lighting fixtures, accent lighting and several other types of ornamental lighting can be categorized as contemporary lighting. When a user is clear about the kind of lighting he requires, the market can give him a wide range of choices to suit his needs. The variety of lighting fixtures available is sure to delight a consumer and fulfill his needs to satisfaction. http://danceshoes.hyperphp.com/ http://bariatric.atwebpages.com/ Alarm Car System Vehicle

Care and Troubleshooting of your Halcyon HID

Care and Troubleshooting of your Halcyon HID Light

The light emitted from the HID arc tube is intense and appropriate safety precautions relating to exposure protection are required. Metal halide bulbs operate at very high temperatures and pressures. The quartz glass of the bulb itself must be kept clean. The glass lamps should be handled with care giving special attention of the quartz arc tube. The Halcyon HID light is a DC lamp; proper electrical wiring polarity must be observed to prevent damage to the lamp.

CAUTION: Ultraviolet, visible, and infrared radiation is emitted from metal halide lamps. Possible skin or eye irritation can result from exposures exceeding 15 minutes. Do not stare at exposed lamp in operation. During operation, the bulb should be enclosed in a housing to prevent injury. Do not remove bulb from equipment until it has cooled. Never handle the bulb when it is operating!

Protect the quartz arc tube when handling the lamp. Keep the arc lamp clean. Do not touch the quartz tube, the inside surface of the reflector, and the connecting wires. Contamination can degrade lamp performance or cause premature failures. If necessary, clean the lamp by wiping with a lint free towel or swab immersed in denatured alcohol.

While HID bulbs last considerably longer than halogen bulbs, you should be aware of several characteristics that indicate that a bulb is approaching the end of its lifespan. Initial symptoms of end-of-life are characterized by low light output and/or intermittent starting. Visual signs include blackening at the ends of the arc tube and electrode tip deterioration. Note that HID bulbs contain metals, including mercury, that are harmful to the environment. Please be responsible in securing proper disposal of an HID bulb.

The bulb and ballast are sensitive to external operating temperature. Although the Halcyon HID light doesn't generate the amount of heat of a halogen light, it should be treated like any other dive light. The HID lamp should only be operated while in the water, to provide proper cooling for the lamp assembly. While transporting your HID light, please don't leave the light in direct sunlight or in a car's interior on a hot day.

If you are experiencing problems with your HID light ahead of its expected lifespan, take a second to inspect the bulb and ballast assembly http://danceshoes.hyperphp.com/ http://bariatric.atwebpages.com/ Alarm%20sensors Detectors Parts
