Powa Beam 7" 35W Xenon HID Spotlight Fixed Mount Spotlight.

This spotlight has a 175mm (7") diameter case with an all metal construction. It basically has the same reflector, case, bracket and quality handle as the PL175 halogen spotlight however it has a High Intensity Discharge (HID) globe, with the ballast mounted on the back of the case. The standard globe used in this light has a 6000K colour temperature and is 12v 35w. 

Like all Powa Beam Spotlights, the PL175HID is hand focused for maximum performance and every part is replaceable.

What is HID? 

HID lighting system stand for High Intensity Discharge Lamp. The HID lamp is a system that produces light by putting xenon gas and metal halide salts into the light emitting tube installed inside the HID lamp. The electrons inside the light emitting tube collide with the metal atoms, using 20,000 volts generated from the control system (ballast) to produce light.

Work Theory:

Bulb: The Xenon Gas and mercury Metal Halide Salts existing inside the light emitting tube causes the molybdenum electrodes on both sides to plasma discharge and create energy, which in turn produces light.

Ignitor: This is an electronic amplifier that receives electric current from the ballast and boosts voltage to ignite the Arc Light Source in all environments. It initialises plasma discharge within the source by delivering a high voltage pulse to the electrodes.

Ballast: This is an electronic control unit used to initialise arc and supply a stabilised power supply to the bulb and ignitor during normal arc conditions.

What are the Advantages of HID?

Durability: Improved durability as road vibrations can cause damage to coil lighting technologies.

Higher Colour Temp: More closely reflects that of natural daylight and improves both light intensity / reflection and light distribution, for earlier recognition of animals, people and objects. 

Longer Service Life:  A HID lamp will last, on the average, at least 5 times longer than a halogen bulb. In practical terms the life span of the bulb is equal to that of the car, so the bulb should only need replacing in exceptional circumstances.

Low Power Consumption: The standard 35w HID system produces on average 4.5 times the amount of light however it only uses approx. 3.0amps , compared to a standard 100w halogen which uses approx.8amps.
