1. What is a halogen lamp?

 

Halogen is a type of incandescent bulb. It has a tungsten filament just like a regular incandescent that you may use in your home, however the bulb is filled with halogen gas, usually bromine or iodine. A halogen light source provides a crisp white light with an outstanding color rendering which makes this bulb ideal for many applications.

 

 

2. What are the advantages of a halogen lamp?

Halogen light bulbs have many advantages:

 

-High quality of light with excellent color rendering (Ra=100)
-Fully dimmable

-Halogen light is environmentally friendly and stands out for its sparkling light effect
-Philips Halogen lamps are available in a large variety of shapes and sizes and are designed to suit a wide range of luminaires and applications
-Longer life time than a conventional incandescent
-No warm up time, Philips halogen bulbs deliver instant light

 

 

3. Are all halogen lamps dimmable?

 

 

Halogen lamps are designed to operate at very high temperatures to ensure optimal performance. Dimming at above 60% of the rated volts can be done. It is recommended to revert to full brightness for one minute prior to switching the lamps off.


4. Why does a halogen bulb last longer than incandescent?

 

 

Halogen light bulbs last two to five times longer than traditional incandescent bulbs. This is due to the halogen regenerative cycle process. The halogen gas helps the evaporated tungsten particles to deposit back on the filament instead of the lamp wall. This postpones the breakage of the filament and allows the lamp to extend its life.

 

 

5. How do halogen lamps enable constant light output?

 

 

Halogen lamps are able to maintain constant light output over the life of the lamp since the tungsten particles get redeposited on the filament of sticking to the lamp wall, therefore significally reducing bulb blackening and maintaining light output.
