LED Light Bulb

Most people may know that LED stands for light-emitting diode. LEDs are actually semiconductors that produce more efficient light than traditional light sources. When electricity passes through them, they emit energy in the form of light. These semiconductors are doped or injected with chemicals that determine their light color. LEDs convert the majority of energy to light, as opposed to incandescent bulbs that produce light as a by-product of being heated. For this reason, LEDs can be up to 90% more efficient than traditional household filament light bulbs.
LEDs have been widely used as displays and indicator lights for nearly 40 years. It was only recently that engineers figured out how to make and mass-produce bright, white LEDs that can be used for general-purpose lighting. The high brightness and point-source characteristics of LEDs have made them the first choice for traffic lights and car tail lights that require high visibility and dependability. Other LED lights like LED spot light bulbs; LED tube lights are all familiar to the public.
But few people know how to select LED lights. The following are some tips for your reference.
While the initial cost per bulb is still high, the integrated lifetime cost of an LED light bulb is actually lower than that of equivalent incandescent and CFL bulbs. Taking into consideration energy costs as well as time and resources required to replace incandescent and CFL bulbs, an LED bulb that lasts 80,000 hours has a much lower lifetime cost.
When selecting LED light, you will quickly find that the market is filled with all kinds of products. Many of these bulbs are relatively inexpensive; however, you may find that many of these LED bulbs consist of questionable materials and dubious craftsmanship. Good LED light bulbs cost more than these cheap ones because they use high-quality chips with prices firmly set by reputable manufacturers. These though selecting LED light bulbs are more expensive, they are of superior quality.
LED light bulbs can not be dimmed with traditional dimmers. LEDs require constant current to operate. As a result, if a standard dimming method is applied, it will flicker at regular intervals, or worse, simply not work. Therefore, selecting LED light, a 0-10V dimming module is required in order to trick the LED into emitting less light. In theory, all LED lights are dimmable with this module.
There are many other tips on selecting LED light that can not be listed there. But do keep in mind these tips when purchasing LED lights.
