There are three kinds of lighting commonly employed in most buildings: incandescent lighting, compact fluorescent lights, and LED lights. Incandescent lighting is the oldest of the three and, at this point, the most commonly used. Compact fluorescent lights arrived on the scene after that, with many improvements and they proved to be much more efficient than incandescent light bulbs. LED lights, or light emitting diodes, were next and blew incandescent and compact fluorescent lighting out of the water. All three lights differ in how they utilize electricity and direct current, how much they cost, and how much maintenance they require. Whether purchasing a commercial LED flood light or one simple incandescent bulb for a desk lamp, it\’s important to know what you\’re purchasing and what it entails.

Incandescent light bulbs haven\’t changed much since Thomas Edison invented the light bulb. They consist of a simple glass shape, usually molded while hot in a process called glass blowing, and have a coil of tungsten wire on the inside. That tungsten wire absorbs electricity when the switch is turned on, closing the circuit. The wire glows red hot, and releases energy as both heat and light. Because of the manner in which current is used in an incandescent light bulb, as well as its archaic nature, they happen to be incredibly inefficient. Incandescent light bulbs release about ninety percent of their energy as heat, using only ten percent of it as visible light. As a result, the light bulbs also burn out more frequently and must be replaced more often.

Compact fluorescent lights are composed of a mixture of argon and mercury vapors, housed in a spiral shaped tube, coated on the inside with fluorescent coating. When the vapors are energized, their atoms get excited and jump to the next level. This causes a release of ultraviolet radiation, which is then absorbed by the fluorescent coating. That fluorescent coating converts the ultraviolet light to visible light, which can then be used to light an entire room or building! Fluorescent lights are more efficient, and give off less heat than incandescent lights, but they are not inherently perfect.

LED lights, as their name suggests, consist of a diode and a semiconductor that emits light. The diode allows current to travel in only one direction, and the semiconductor determines the color of the light that is released. Due to the nature by which LED lights use the electricity sent to them, they tend to be seventy-five percent more efficient than incandescent light bulbs and twenty-five percent more efficient than compact fluorescent bulbs. This also results in LED lights lasting a lot longer than other types of lighting for the sheer fact that they don\’t \”burn out\” as often.

Although the initial cost of LED lights is a hard pill to swallow, especially compared to incandescent lights being only a few dollars at a grocery store, they wind up being much cheaper over time. Rebates are available for LED lights, while none are available for incandescents and just a few for compact fluorescents. Also, the fact that they use energy more efficiently will significantly decrease bills, even when purchasing an commercial LED flood light.
