This is bad news on two fronts: The filament is constantly degrading, and thus limits the life of the bulb. In normal use incandescent lamps typically last only 750 to 1,000 hours. The blackening of the glass also
Prescription drug coverage is an important aspect of overall health care coverage. This article will briefly discuss the types of coverage that are available, as well as some things you should be aware of when choosing a plan.Most people obtain their prescription drug coverage as a part of their overall medical insurance plan. Most medical plans include some form of prescription drug coverage, and some states actually require empl
Tungsten Halogen lamps were invented in 1958 by the engineers of General Electric. Producing a very strong, white light they are now used in many applications from automotive to retail display lighting. To understand their many advantages and consequent popularity we will compare the way in which ‘normal’ incandescent lamps work.
Incandescent Lamps
A normal incandescent lamp comprises a tungsten filament inside a glass envelope filled with inert gas such as argon or nitrogen. An electric current heats up the filament to about 3000 degrees making it a thermal radiator. At this temperature about 5-10% of the electrical input is converted to visible light and about 90% to heat, which is not particularly efficient!
During this process the filament vaporises and tungsten atoms stream towards and deposit on the cooler glass walls of the lamp envelope, which, over time becomes black. You will probably have noticed this in some of your older household lamps.

Do you know what is Googling? We hear and read that different people all over the world are Googling. It has become a house name. It is on TV already.Googling is an expression used to name the regular practice of search for things on the Internet. For example, if anyone is looking for a work at home based business opportunity; it goes to Google web page and search it there. And Google is the higher up, the most used and most relev

If you have been online for a while, one of the most well know ways of selling online is to build an optin email list or ezine. So now there are thousands of email ezines on just about every possible topic.Hey- it is a proven tool, so you should use it however some ezine owners have a mental break down when they get some subscribers, its like AHA! Now I have your email address, I am going to sell you every affiliate program I can

Being an approved cruise enrichment lecturer is the greatest gig on the seven seas. The deal is simple: you furnish the cruise lines three or four 1-hour lectures on subjects you love and you get a free cruise for yourself and a companion. The best part is the lectures are usually scheduled on sea days so you’ll have every port day totally free to explore. Further, you cruise as a passenger (not a crew member) so you’ll ge

Running a home based travel business is the wave of the future. Though it may seem simple to run a home based travel business, you need to know what kind of home based travel business you want to run and what types of situations you will deal with in running a home based travel business.Basically, there are two types of home based travel agents – referral agents and booking and selling agents. Referral agents do not book nor do
This is bad news on two fronts: The filament is constantly degrading, and thus limits the life of the bulb. In normal use incandescent lamps typically last only 750 to 1,000 hours. The blackening of the glass also impairs the performance of the lamp for the deposited Tungsten material absorbs light. To decelerate this blackening conventional incandescent lamps have a ‘big’ envelope with a wide surface area to spread the deposited tungsten.
The Halogen Breakthrough
The engineers of GE discovered that when Halogen gas was added to the envelope tungsten atoms did not collect on the walls. The Halogen atoms attach themselves to the vaporised tungsten atoms and transport them back to the filament where they are reused. The Halogen atoms then go back out into the lamp atmosphere and search for more vaporised Tungsten atoms. This continual process is known as the ‘Halogen Cycle’, and it signalled a breakthrough in lamp technology and design.
- Since the tungsten filament is continually ‘re-fed’ with atoms it may be operated at much higher temperatures. This results in a much brighter, whiter light. Halogen l
