There have been many electric light bulbs made in the world, all using different amounts of electricity, some better then others. Today we have the choice between many, but it all started with the first electric light bulb invented by Humphry Davy in 1800. Since then many more have been made and we have the best use of light there ever was today.
A light bulb is a glass envelope that provides light by passing an electric current through a filament. The filament creates the energy that makes the light show.
Light bulbs are used daily in almost every room and building in the U.S.A. They are essential to our daily uses. We use extreme amounts of energy each day to keep our homes lit.
Today we are faced with many choices of light bulbs and we all want to say money on the amounts of energy we used. “Electric lighting burns up to 25% of the average home energy budget.” What light bulbs are the best to buy, to save the most amount of electricity we use each day? We are given too many options, how do we know what is the best? There are hundreds of different light bulbs we can buy, there are 271 results for just the LED light bulb, and that is only one type of bulb.
Type of Bulbs:
1. Incandescent light bulbs: These light bulbs have a very thin tungsten filament. The filament is what gets very hot from the electricity, which runs through it. The heat that is produced creates “white” energy, which is visible light. The problem with these bulbs though, is that the heat wastes a lot of electricity. The incandescent light bulb produces 15 lumens per watt of input power. This light bulb was made in 1802 and still used today. It has both advantages and disadvantages to using it. Great for small area li...

...hts. If this is the case, then why are they not the most common light used today? The answer to this is that the cost of the LED bulbs is not economically due able for more people. Incandescent light bulbs have been around for so long, because they work and are cheap. They do the job, but are it most efficient. For most people though efficient is not their main concern. Therefore, today there is still a large variety of the light bulbs that are purchased and which of them is their preference.

- The Light Bulb and How It Works When examining a light bulb, one can describe the light bulb as a device that provides light when it is switched on from its power source. It is used when our natural source of light (the sun) happens to reduce its output. We as humans use it in order to see when it is dark. The light bulb works by electricity flowing through the wire causing it to heat up. The heat makes it glow. It heats up because of resistance. As electricity passes through an object, the substance it is passing through tries to hold on to the electrons.It is as the electrons force through that some of the force present is absorbed and given off as heat.As th...
