It is a known fact that the worldwide energy crisis is growing and for that reason governments and environmental protection organizations are trying to motivate people to cut down their use of energy. Among the best ways to accomplish this is to use energy efficient light bulbs. These bulbs not only reduce the amount of energy needed, but as an added bonus they also save you money.

You can actually save hundreds of dollars a year on your energy bill just by changing the types of light bulbs you use. Most people do not realize what the differences are between different types of light bulbs and how they can help themselves save money.

The first thing you need to do is become familiar with the various kinds of lighting available. Lighting can be separated into three general types and they are incandescent, discharge and light-emitting diodes. Incandescent lamps are the oldest variety and are easily recognized by the glowing filaments inside of them. They are the most common type of lighting used, but are also the least efficient of all the options.

Discharge lamps are another type of light bulb that is a little more efficient. Understanding how discharge lamps work is important. Fluorescent lamps and high-intensity lamps are also in the discharge lamp category. These three different types of lamps are categorized for using glowing gas.

Light-emitting diode light bulbs are not used in homes that often. It’s important to understand that discharge lamps use glowing gas, while incandescent lamps use a glowing filament. The glowing gas is actually significantly more energy efficient.

With these type of light bulbs understanding the deeper side of efficiency is important. Your job as a consumer is to understand and have some knowledge of the product you are purchasing and how it helps you to save money. The amount of light that is emitted from a light is referred to by the term luminous flux.

This is measured by lumens or lm. Approximately 700lm is emitted by a the common 60W incandescent light bulb. Then there is the 58W tubular fluorescent lamp which emits about 5000lm.Interestingly, these two light bulbs which cost about the same, emit significantly different quantities of light.

Also keep in mind that there is a term used to describe lamp efficiency and this is known as efficacy. There is a mathematical formula that you can use to figure out what the efficacy of a light bulb is. To found out you will first have to realize that the he formula is actually a ratio between the amount of light that a lamp produces and the amount of power required to produce that particular amount of light.

The best way to keep our electricity bills lower is by using light bulbs that are significantly more efficient. By using these light bulbs you will not only save money, but you will save energy which in turn then helps to save the environment.
