LED GU10 Light Bulb Buying Tips

Updated on August 1, 2010

Just as incandescent light bulbs are slowly being replaced by more energy efficient compact fluorescent lights (CFLs), the market share that CFLs hold is gradually losing ground to LED GU10 lights. These bulbs are based on light emitting diode (LED) technology, where diodes made of semiconductors produce light when a current passes through them. These new kinds of lamps are very efficient and environmentally friendly, offering a large amount illumination in relation to the amount of electricity that they consume. This can translate into savings of hundreds of dollars over the life span of the lamp. Also, they last for years, keeping the buyer from having to purchase new ones regularly when they inevitably burn out.

While GU10 LED lighting has several benefits like reduction in energy consumption, lower heat output, and long lifetime, they are a relatively new technology and have some limitations. First of all, they do not produce as much light as incandescent types. Next, they only illuminate objects in one direction. Their light does not spread out light other styles. Instead, it is focused on a limited area. As such, these are currently not good choices for lighting whole rooms. Instead, it is best to take advantage of their unidirectional focus in the form of track spots or floods that are used to highlight certain areas of a room.

Furthermore, they don’t necessarily provide the same quality of illuminations as incandescent lamps. Incan descents produce a more uniform, warm, illumination. In contrast, newer, energy efficient lamps come in several varieties in terms of the color that they emit. Light emitted from bulbs can be measured in terms of color temperature. Traditional incandescent lamps have a color temperature of 2,700 to 3,300 Kelvin. Newer types like LED GU10 bulbs come in a variety of temperatures. Choosing one that is closest to the color of incandescent types is most desirable for indoor settings because we are used to it. If lamps with greater color temperature are used, they can cause objects in a room to have a bluish shade to them. The light quality can also look harsh and sterile, creating an inhospitable environment.

These kinds of lamps are slowly becoming available for purchase in major home improvement stores and also on the internet, but comparing them can be a difficult task for the uninformed. Each bulb should have two ratings on it. One rating is the wattage, which measures the power consumption of the device. The other rating is the lumen rating. This number represents the amount of light that it emits. In order to make a comparison, it is useful to find the ratio of wattage to lumens by dividing the number of lumens by the number of watts. An acceptable ratio is between 50 and 100 lumens per watt. 50 is the minimum ratio that a person should purchase, while 100 is an excellent rating.

This type of lighting is fairly new to the marekt. While they have some limitations, they also possess many advantages which may appeal to certain buyers. In years to come, as technology develops, these bulbs will surely gain widespread use. For more useful information on LED GU10 bulbs visit Village Views.

      Some good information.

      I am sure that these LED GU10's will take over from halogens. It is just a matter or time! Also the MR16 12volt versions are good and can save you $200 in lifetime costs if you do the maths
