Are Halogen Bulbs Dimmable? [Full Guide]

All halogen light bulbs are dimmable.

Halogen lights work the same way as incandescent bulbs. If you lower the filament temperature by changing the voltage with a dimmer you will get less light output and dimmer lights.

If you dim the halogen bulb to about 20% or less light, the filament temperature declines, it can also cause darkening of the quartz capsule and because of that, it may shorten the life of your halogen bulbs, but this is perfectly normal so don’t worry. The halogen bulb burns out the same way as an incandescent bulb, the tungsten filament breaks.

A universal dimmer switch is a good choice for halogen bulbs.

All halogen bulbs are dimmable and finding a dimmer switch for halogen is easy.

If you just have one bulb that you want to dim, any dimmer should do the job for you.

If you are planning on dimming several halogen bulbs with the same dimmer, just multiply the bulb count with the wattage of the bulbs.

For example, 7 halogen bulbs and each bulb is 75W= 525W. A halogen dimmer switch with a 600W rating will fit perfectly.

Just make sure that:

  • The dimmer is rated for the same voltage as your light fixture.
  • The halogen bulbs total wattage is below the maximum rating of the dimmer switch you are using.

Are halogen bulbs being phased out?

It can be challenging to find halogen bulbs because retailers must replace halogen with something more energy-efficient bulbs, like LEDs.

The halogen bulbs will be slowly phased out, with people expected to replace the halogen light bulbs that they have in their homes as soon as they expire.

What is the advantage of halogen bulbs?

The color of the light is not so yellowish if you compare it to incandescent light bulbs, the halogen reminds more of the sunlight.

The size of the bulb is small, lightweight and they are easy to produce.

Halogen bulbs (2000-4000 hrs) tend to last longer than incandescent (750-1500 hrs) light bulbs.

What is the disadvantage of halogen bulbs?

They operate at a much higher temperature than incandescents and LEDs.

So these high running temperatures can present a safety concern in some fixtures.

You should not touch the bulb, because the salts and oils from your fingers can damage the bulb, by causing the heat to concentrate on the dirty part of the bulb.
