General Characteristics of halogen lamp

Energy Saver replacement for Red / Ceramic Coated Halogen Lamps

High Efficiency
The lamp is made of quartz glass. The compact lamp supplies a highly luminious output per watt. The Halogen cycle minimizes evaporation of tungstan filament.
Long life
The halogen cycle guarantees extremely long lamp-life. Service life is about twice that of ordinaly incandescent lamps.

Economy
The long life of halogen lamps a further reduction in maintenance and related expenses
Stable color temperature
The halogen cycle - a chemical reation in which evaporated tungsten particles are returned to the filament- blackening of the bulb wall and thinning of the tungsten filament are kept to a minimum. Light intensity and color temperature remain stable throughout the life of the bulb.

compact design

The ceramic cap containing a contact button is connected via a molibdenum foil seal to a tungstan filament enclosed hermetically within a transparent qurartz glass envelope. The filament is operating at a temperature of about 3000K in an atmosphere of inert gases like kripton,argon and nitrogen as well as added halogen like iodine or bromine.

Halogen cycle

Tungsten atoms which leave the surface of the hot filament will chemically combine with the halogen to form halides. These halides will attack the glass bulb and will not condensate there as long as the temperature of the bulb is above 250C In the convection current of hot gases the halides will come back into the high temperature zone around the filament, where the halide molecule will dessociate. The tungsten atom will redeposit on the filament and the free halogens are readly available for another reaction with evaporated tungsten.This process, called halogen cycle,effectively prevents blackening of the bulb wall and thinning of the filament's tungsten, thus resulting in longer lamp-life.

light beam

Rectangular formed beams of a incandicent lamp are simple to cover a wide area by the proper reflactor type.

Precaution for handling halogen lamp

1. Do not touch the quartz envelope with bare fingers. If touching the lamp is necessary during installation, clean the envelope with alcohol and dry with a clean soft cloth before burning. Contamination of the quartz envelope may reduce lamp performance.
2. Keep lamp seal temperature below 300 C.
3. Keep lamp wall temperature above 200 C to attain full function of the halogen cycle.
4. Keep the lamp free from impact while burning, as this may deform the filament and shorten the lamp life.
