So if you consistently touch a quartz capsule inside a halogen light bulb, your fingers will affect the life of the product. Were incandescents bulbs banned? We explain here. Our CEO uses halogen bulbs in his home. And for all the buzz LED gets , plenty of lighting specialists and designers recommend halogen light bulbs for residential or decorative purposes.
Other than those, here are a few applications where you see halogen bulbs used the most:. Many jewelry stores use halogen mirror reflectors to highlight gold jewelry.
The way the light reflects from the mirror reflector and onto the jewelry gives it a warm, rich, and high-class tone. Some retail stores still use halogen PAR lamps in their track lighting.
Abercrombie, Hollister, and PacSun are a few that use halogen bulbs. You will also see halogens used to heat the food, or in portable projectors. Due to the small size of the quartz, halogen light bulbs can be very beneficial in these niche applications. Topics: Lighting , Halogen , Incandescent lighting. Find the location nearest you.

Understanding how the light bulb produces artificial light helps us and you to troubleshoot when scenarios go haywire. Example: Did you know that some halogen and HID lamps look nearly identical? Knowing the differences in technology will help you quickly identify that you have a halogen lamp in a HID socket. Understanding how the light bulb produces artificial light helps us and you pick out the right bulb for the right application. Let's briefly define halogen light before we jump in.
What is halogen light? How do halogen light bulbs work? Thus, halogen bulbs last longer and are brighter from lack of soot. Light is more easily permitted to radiate out to more brightly illuminate space. The design of the halogen bulb has to be a bit different too. A greater heat is required to put the tungsten back in the filament.
This higher temperature creates higher pressure so that halogen bulbs must be made of special hard glass. But what most of us see as the main difference is brighter whiter light.
Now for just a little bit more detail. A halogen light bulb is like a bulb within a bulb. A small bulb holding the filament also holds the halogen gas. Around this smaller bulb is another bulb or shell made of hard glass.
In your ordinary incandescent light bulb, the tungsten filament is out amongst the argon gas it is pressured with and it is surrounded by only the shell. This shell does not have to be as hard as the halogen shell. Having described the nature of the halogen light bulb, we should look at the pros and cons of halogen bulbs. Because the halogen bulb produces so much light for its size, it is used in doctors' penlights to look in eyes.
Author: Hanabishi. Surface contamination will damage the outer halogen bulb. These contaminants, most often human oil, create a hot spot on the surface when the halogen is turned on. When heated, the bulb becomes a weaker crystalline form and will then allow gas to leak. This will cause the filament to burn up. It is also possible that the weak spot will bubble out. At some point, the bulb could explode. When I would change bulbs in a projector at school, the bulb's plastic envelope had instructions to use the plastic to hold the bulb.
It also told the user another method - holding the bulb at the bottom where there was ceramic. If contaminated, I would clean the bulb with alcohol. Not doing so would result in burnout or possible explosion upon sending voltage through the bulb.
So the bottom line is to be careful in the placement of halogen lights while realizing that they are less expensive than standard fluorescent lighting, but more expensive than CFL twists and incandescent light bulbs.
They are good for specific tasks e. Content is for informational or entertainment purposes only and does not substitute for personal counsel or professional advice in business, financial, legal, or technical matters.
Question: I was given an Electrix 20 watt halogen lamp. Model volt 60 Hz and boy does it get hot. Halogen bulbs can last approximately twice as long as conventional incandescent bulbs of comparable wattage and color temperature due to the regenerative properties of the halogen gas. As with a conventional bulb, the tungsten filament evaporates when the light is on, but instead of being deposited on the inner surface of the bulb, the tungsten particles combine with the halogen gas and are redeposited on the filament.
This delays both filament failure due to tungsten thinning as well as darkening of the bulb. A halogen bulb can be designed to match the life of a conventional incandescent bulb of comparable wattage but will operate at higher filament temperatures with greater luminance and efficiency.
Because they are more costly to manufacture, halogen bulbs are considerably more expensive than non-halogen incandescent bulbs of comparable wattage. A 4x price difference is not uncommon. Halogen lights are hotter than regular incandescent lamps so protective grids, grills, and housings are often employed to reduce fire and burn hazards.
Although conventional incandescent bulbs do not get as hot as halogen bulbs, they typically lack the safety enclosures used to protect halogen bulbs. For this reason, it is important to prevent bulb contact with skin, cloth, and other flammable materials. How Stuff Compares No nonsense comparisons. Home Index About Contact.
