new types

In recent years, great efforts have been made to create more environmentally friendly products. Light bulbs have been around since Thomas Edison offered the technology in the late 19th and early 20th centuries. However, conventional incandescent lamps are inefficient and use a lot of power. Traditional types work by heating a tungsten filament inside of a glass envelope to thousands of degrees. As the filament heats up, light and heat are produced. These lamps can use a lot of electricity and need to be exchanged frequently when the filament burns out.online ups manufacturerdab4d58ck Recent developments have included compact fluorescent lights (CFLs), which work by exciting molecules of inert gases inside of tubes. They require much less power than incandescent bulbs and last many times longer. But one of the newest technologies is LED GU10 powered bulbs. LED is an acronym for light emitting diode. An LED is a small device made of a semiconductor that emits light when a current passes through it. GU10 LED light bulbs have several advantages over their predecessors.


LED GU10 bulbs are first and foremost very energy efficient and therefore more environmentally friendly. For the amount of illumination that they give off, these new kinds consume very little electricity. By switching to one of these, homeowners can save hundreds of dollars in utility bills over the course of the lamp's lifetime. Not only that, but the environment will be spared the carbon emissions created by producing electricity at power plants. Also, CFLs can contain harmful chemicals like mercury within them. If they ever crack or are disposed of in an improper manner, they can pollute the environment with toxins.


Another benefit is that they produce very little heat. Incandescent lamps (and CFLs to a lesser extent) can get extremely hot. This can pose safety issues for small children, who may touch the lamp. Also, it reduces the chance of a fire. These kinds remain cool to the touch even after several hours of operation. The reduction in heat produced by these lamps can have a great effect on the temperature of a room, keeping it cooler than if it were lit with more traditional types.


Finally, these new types last a lot longer than incandescent or CFL options. For example, one LED GU10 light can last for up to 30,000 hours of use. In comparison, CFLs last between 6,000 and 15,000 hours depending on the model and manufacturer. Incandescent bulbs have the shortest life spans,PAR 38 LED lasting a mere 750 to 1,000 hours. Instead of having to purchase bulbs every few months, with these new lighting sources, homeowners can go years between changes.
