Halogen light bulbs are used because:

  • they can be operated at a higher temperature than can be used for ordinary light bulbs.

    This results in less heat production compared to light output and an overall much higher efficiency in the conversion of the energy which is input - electrical energy - to the energy which is output as visible light.


  • they have a significantly longer useful life than ordinary incandescent light bulbs.

Technical note

The invention of halogen lamps was based on the discovery of a special physical feature: when small amounts of a halogen gas were added to the contents of the light bulb, these were found to help to return large quantities of evaporated tungsten atoms back to the filament. This resulted in a significantly longer lifetime of such lamps.

General note about how all incandescent filament light bulbs operate

An electrical current travelling through the filament of a light bulb makes it glow white-hot and generate both light and heat because of the electrical resistance of the filament.

The filament is normally mounted within a special mixture of noble and/or inert gases held inside the glass enclosure of the light bulb, held at a pressure which is close to a vacuum.

The special mixture of gases prevents the filament from oxidizing and burning away, which would happen extremely quickly if it glowed white-hot in normal air which contains oxygen.

What is the difference between incandescent light bulb and halogen light bulb?

The major difference between an incandescent bulb and a halogen bulb is the gases that each produces within its glass bulb. Incandescent bulbs fill with a mixture of 93 percent argon and seven percent nitrogen, while halogen bulbs adds a halogen gas, such as iodine or bromine. Halogen bulbs are more efficient compared to incandescent bulbs.

When you turn on the switch to the bulb and no light is emitted, the majority of the time, it is the bulb that is no good.

What is the difference between an incandescent and a halogen bulb?

All halogen bulbs are incandescent bulbs but not all incandescent bulbs are halogen bulbs! An incandescent bulb has a filament that heats up and gives off light. in the process, some of the filament evaporates. In addition a halogen bulb has halogen gas. When the bulb is turned off, the halogen gas returns atoms from the filament back to the filament. As a result the filament can last longer.

What is the difference between a metal halide lamp and a halogen lamp?

A halogen bulb is a traditional tungsten filament bulb filled with a noble gas that gives off a soft, yellowish light. In a metal halide bulb, the light emitted is bright white or even bluish. They have a longer life than halogen bulbs, but their brightness can diminish over time.

Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.

What is the incandescent equivalent of a 40 Watt halogen bulb?

A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.

Is the 300 watt halogen linear bulb economical?

It depends on your purpose whether or not it is economical. For some purposes, it is very good. If you are painting and want to see whether or not you need to repaint a particular area while you have your equipment there, it is extremely economical. It can save you big bucks from having to rent expensive equipment a second time. It also depends on what you are comparing the halogen bulb to for the purpose of light.
