Carefully remove the old bulb by gently pulling it out of the socket or clips, being cautious not to apply excessive force. Hold the new bulb with the cloth or gloves and align the pins on each end with the corresponding holes in the fixture’s socket. Gently push the bulb into place, ensuring that it is securely seated in the socket. Restore power to the fixture and test the new bulb to confirm proper function.

How does a Double-ended Halogen Bulb Work?

A double-ended halogen bulb is a type of incandescent lightbulb with two filaments. A double-ended halogen bulb typically has a longer service life and produces more light than a single-ended one.

Double-ended halogen bulbs consist of two filaments in one lamp, allowing for higher wattage with lower operating temperatures.

Double-ended halogen bulbs offer brighter and whiter light than traditional incandescent bulbs.

They can be used in any double-ended filaments application, such as car headlights or landscape lights. They are also used in stage, theatre, and disco lights.

What are the Benefits of Using A Double-Ended Halogen Bulb?

Double-ended halogen bulbs have several benefits when compared to other types of bulbs. Double-ended halogen bulbs are extremely efficient, burning brighter and longer than other lightbulbs.


Since they burn brighter, double-ended halogen bulb light is more even; this eliminates too bright or too dark areas. They also burn a cooler, which further enhances the evenness of the light.

Double-ended halogen bulbs are perfect for task lighting or up-lighting because of their efficiency and light distribution.

How to Change a Double Ended Halogen Bulb: 8 Steps to Follow

Step 1: Turn off the Power

Turn off the power to the light. This can be done by turning a switch on or hitting a circuit breaker in your fuse box. Turn the light switch off and unplug the lamp.

Step 2: Remove the Old Bulb

Remove the glass or plastic cover that covers the bulb. Use gloves to protect your hands from any leftover oil on the bulb that might cause an allergic reaction. Then, carefully remove the old halogen bulb.


There will be two metal prongs holding it in place, twist them counterclockwise until they loosen, and pull out both sides of each prong until you can remove the bulb. Be careful not to touch the glass part of the halogen bulb because it could start a fire.

Step 3: Clean Out the Metal Prongs

Clean out any dirt or grime from the metal prongs using an old rag. If there is still dirt on the metal prongs, you risk an electrical fire.

Step 4: Insert the New Bulb and Twist-On Tightly

Insert a new halogen bulb into the metal prongs of the lamp and twist on tightly to ensure it is secure. Be careful not to touch any glass or oil on this halogen bulb from your fingers.

Step 5: Turn on the Power and Test Your Work

Turn your power back on and test the light fixture. This might require someone to stand under the lamp for a few minutes to ensure it does not burn out.

However, you should have a working halogen lamp if you did everything correctly!

Step 6: Dispose of Your Old Bulbs

Take your old halogen bulbs and put them in an outside covered trashcan. Halogens contain a minimal amount of mercury and can cause harm to children and animals if they touch them.

Be sure to return the lamp globe to its original position after cleaning up all broken glass from replacing the bulb.

Step 7: Clean Up any Broken Glass

Use a broom to clean up the broken glass from your bulb, being careful not to cut yourself.


Use gloves and hold pieces of glass carefully to ensure you do not get them on your skin or in your eyes. Put all broken glass pieces into a zip-loc bag and put it outside in a covered trashcan.

Step 8: Put the Cover of Light Fixture Back

Replace the cover of your light fixture and put it back in its normal spot.

Unless you plan to replace the other bulb in this lamp, make sure you turn off the power before replacing any other parts or testing out your new bulb!

Safety Precautions You Should Take:

1. Ensure that you are not directly looking into the bulb’s light.

2. Ensure that there is no flammable material in your workspace.

3. Turn off and unplug the lights before starting maintenance on them.

4. Wear safety goggles to protect your eyes from glass particles or chemicals while handling the bulb and cleaning up afterwards.

5. Don’t touch your eyes while handling the bulb, and do not rub your eyes until you have washed your hands thoroughly with a disinfectant soap.

6. Keep children away from the work area, so they don’t hurt themselves by coming into contact with any chemicals or glass particles.

7. Make sure that there is adequate ventilation around the maintenance area.

Common Mistakes to Avoid When Changing Double Ended Halogen Bulb:

1. Using the wrong bulbs as an Energy Saving Bulb. Energy-saving light bulbs are not always compatible with your current halogen sockets/ballasts.

Always check that your current bulb is a double-ended halogen bulb, or you could risk a fire hazard!


2. Touching the glass of the new bulb before installing it into your lamp fixture. The oil from your hands can contaminate the bulb, causing it to overheat when in use. Make sure you handle the bulb by its base only.

3. Failing to tighten the new bulb into place securely. Not putting your new halogen light bulb in tightly enough could cause heat or fire damage to your lamp fixture and surrounding area, e.g., curtains and walls.

4. Use a bare-hands to thrust the new bulb into place and immediately switch on your lamp fixture.

Once you’ve placed the new halogen bulb securely into position, always use a pair of tongs or an oven glove to turn it off/on until cooled down safely.

5. Handling the light bulb further after touching the glass before installing it. The oil from your hands can contaminate the bulb, causing it to overheat when in use. Always handle the new halogen light by its base only!

Should You Clean Double Ended Halogen Bulb?

Cleaning a double-ended halogen bulb is beneficial to your wallet and for safety’s sake. Savings lie in the fact that a clean bulb burns brighter and lasts longer.

Safety lies in the fact that dirt obscures the halogen bulb’s ability to focus light, making it seem brighter.

If you’ve ever burned your fingers or toes because you didn’t see where the bright spot of a halogen bulb was, you know how important good lighting is.

Dirt can also affect the bulb’s ability to focus light, even if it doesn’t cause injury. Some people say that the bulb works better if it’s dirty.

This is not true. It may work better in the dark, but it still wastes energy and costs you money.

What’s the Difference Between Double-ended Halogen Bulbs and Single Halogen Bulbs?

A double-ended halogen bulb has two filaments, while a single-ended halogen bulb only has one.


Both halogen bulbs can be identified by their shape: double-ended halogens are long and thin, while single-ended halogens are shorter and wider.

Double-ended halogen bulbs cost a little more than single-ended bulbs, but they last longer and burn brighter.

They are often used in outdoor lighting because they can survive cold temperatures. However, Double-ended halogen bulbs should be changed every couple of years.

Frequently Asked Questions(FAQ):

Halogen bulbs produce a good amount of heat. A halogen lamp has a quartz envelope and is filled with halogen gas and vaporized tungsten, producing around 30% more light than the standard bulb while still projecting heat out to its surrounding environment.

This can be beneficial if you’re looking for lamps that provide good illumination and emit heat. However, if you want lamps that don’t emit too much heat, you might want to look elsewhere. Halogen bulbs can get very hot (up to 200C).

In addition, if they are used in areas where the surrounding environment is too close for comfort (e.g., in a wardrobe next to clothes), it can cause the clothes to burn or melt; therefore, halogen lamps are not recommended for such environments.

Halogen bulbs can last anywhere from 2000 hours to 8000 hours (compared to standard incandescent bulbs that only last around 750-1000 hours).

So, they do last a fair bit longer than conventional incandescent light bulbs.

However, as halogen bulbs heat up during operation, the filament stretches and ultimately breaks due to increased vibration from higher temperatures.

This usually happens when the bulb is only a few months old, and so in this sense, halogen bulbs do not last quite as long as standard incandescent light bulbs.

The power usage is greater for halogen lamps than standard incandescent lights in terms of energy consumption.

Various factors contribute to this – apart from the heat produced, halogen lamps draw more power than standard light bulbs because they operate at a high voltage (between 12 and 36 volts).

Halogen bulbs usually use around 50 watts of energy, almost double that of conventional incandescent lights, which typically use around 28 watts of power.

However, halogen bulbs use this increased energy to produce around 30-33% more light than standard incandescent bulbs, which will illuminate darker areas better so you won’t need to use as many lights in total for your home or office.

Final Words

Now that you know how to change a double ended halogen bulb, it’s time for the next step. Get yourself some gloves and an oven mitt, so your hands stay clean while doing this project.

You’ll also need to find out where the bulbs are in your light fixture. This is usually on the back of the lamp or inside the top part of it if they’re hanging lamps.

It can be hard to see because these fixtures were made before lights became more energy-efficient.
