FAQs about Halogen Bulbs

What is a halogen bulb?

A halogen bulb is an incandescent bulb with a tungsten filament that is surrounded by halogen gas and, often, is encased in a quartz envelope.

How do they work?

Halogen gas in the bulb mixes with vaporized tungsten from the filament and returns it to the filament before it settles on the outer bulb shell. As a result, the bulb stays clear, and the light remains consistent over the life of the bulb.

How does halogen differ from standard incandescent?

Halogen gas allows the filament to be operated at higher temperatures and higher efficacies resulting in better color temperatures and longer life cycles than standard incandescent.

Can halogen be dimmed?

Yes, they can be dimmed with the same dimmers that standard incandescent bulbs use. It is recommended to periodically run the bulbs at full power (inducing the tungsten-halogen cycle referred to above) to clean the tungsten off the bulb wall, enhancing the efficacy over time.

Are halogen bulbs safe?

Yes, halogen bulbs are very safe provided that you use some common sense and follow manufacturer instructions when handling.

Tips for handling halogen bulbs:

•Only use halogen bulbs in approved fixtures. Approved fixtures are designed to contain any parts of the bulb upon the event of a lamp burst.
•Always allow the fixture to fully cool before handling.
•Only use the bulb type, rated wattage and voltage that the fixture specifies.
•Do not touch the bulb surface with your bare hands. Oils from skin can cause hot spots resulting in shorter bulb life. Bulbs can be cleaned with a soft cloth and rubbing alcohol.
•Keep hot bulbs away from flammable materials such as paper and fabric.
•Do not drop, crush, bend or shake them; vibration or impact can cause filament breakage.
