Longer Useful Lifetime Is Just One Advantage Of

The chief advantage of "6 watt GU10 LED" for home lighting and commercial lighting is its energy efficiency. The 'GU10' indicates that it has a bayonet fitting. It was designed to provide a more energy-efficient to the ordinary incandescent light bulb. The same may be said for those fitted with an Edison screw. There are a number of different varieties of LED light bulb.

Another big advantage of LED light bulbs over incandescent or fluorescent tubes is their longevity. Although they cost more to purchase initially, they have a useful life of approximately 20 years. Over this same time period, it may be necessary to change a incandescent bulb around 22 times. Additionally, they do not contain mercury, unlike fluorescent tubes.

The light source for an LED lamp is an array of light-emitting diodes. Three types are currently in use. The type most in use employs semiconductors. Others include organic LEDs (OLED) and polymer-emitting diodes (PLED). The latter are not available commercially.

This particular bulb is a dimmable spotlight. With a brightness of 480/540 lumens, it is comparable to 70 or 80 halogen lamps. The beam angle is 88 degrees. It has a ceramic base for optimal cooling and an aluminum body. This type of light bulb typically emits a huge amount of heat, and some form of 'heat sink' is absolutely essential.

Whereas other types of technology cast light in all directions, LED bulbs do not. They are unidirectional. In those instances where non-directional light is desired, a diffuser can be used. Another option is to mount multiple LED bulbs oriented in different directions.

For domestic use, these bulbs are found in gardens and walkways, flashlights and bicycles. They are also used in agriculture, both commercial and domestic (grow lights). Their original application was by NASA to grow plants in space. Commercially, they are used for traffic lights.

This light form is used to creative and breathtaking effect on commercial buildings. The Sky Tower in Auckland, New Zealand is one example. This spectacular example of energy efficiency may be viewed from as far as eighty kilometers away. Another popular landmark is London's Telecom Tower. It's constantly changing array of lamps cast a multi-colored homing beacon to late-night partygoers all over the capital. The 4,500 lights that make up the Torre Agbar (Agbar Tower) in Barcelona were designed by Yann Kersale. Its sixteen million colors can change in a heartbeat for a shocking effect.
