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.

All you have to do is change the light bulbs you use and replace them with energy efficient ones in order to reduce your electric bill by hundreds of dollars every year. There are many differences, though, between the various types of light bulbs and it is a fact that most people don’t know about this orof how they can save money using them.

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.

Another type of light bulb that is a little bit more energy efficient is discharge lamps. It is important to understand how discharge lamps work. Discharge lamps are characterized for using glowing gas. Fluorescent lamps as well as high-intensity discharge lamps also fall under the category of discharge lamps.

Light-emitting diode light bulbs are the third kind, but are not often found in homes. Knowing that discharge lamps use glowing gas and incandescent lamps use a glowing filament is important, especially since the glowing gas is the much more energy efficient choice.

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.

Another significant thing to understand is the word that is used when referring to lamp efficiency. Efficacy, is a term used when describing lamp efficiency. If you want to figure out what the efficacy is there is actually a formula that is used to accomplish that. The formula to do this is simply the ratio between the amount of light produced by a lamp and the amount of power that is needed to make that amount of light.

In order to lower your electric bills, you will have to choose light bulbs that are energy efficient. This way you not only keep more money in your pocket, but you also conserve energy which in turn is good for the environment.
