A light emitting diode (LED) is controlled by a circuit board and a computer chip that can efficiently duplicate almost any color found within the visible light spectrum, and choosing the best LED spotlight will largely depend on your requirement for brightness and your preference of coloration. When searching for a top quality LED spotlight, there are a number of factors that you should consider, because there is a huge variance in performance, efficiency, brightness and durability. Traditional incandescent lighting generates heat in a 360-degree arc and illuminates everything within a direct line of sight of the bulb, but LED lighting typically transmits light in 60- to 100-degree angles. This means that a LED spotlight produces a cooler, more focused beam of illumination that is perfect for highlighting certain features within your residence with a decreased overall brightness that will not overpower or saturate an area. All of these factors should be taken into consideration as you determine the best LED spotlight for any given circumstance.
An LED lighting fixture uses much less energy that similarly constructed incandescent bulbs, with an average usage of 90 percent less power, so it is a relatively common error to compare the overall wattage when making a purchase. A better comparison in terms of performance would be to compare lumens, or lux rating, which is the standard measure of actual brightness. Within residential LED spotlights, a series of tiny bulbs are interconnected to produce a very specific lighting pattern that can be customized to fit almost any living area regardless of size, which makes them optimal choices for a variety of specialized uses. Your needs for brightness and lighting pattern will help you choose the best LED spotlight.
LED spotlights do not transmit within the ultraviolet or infrared spectrums that the human eye can not see, so they produces 100-percent visible light and a wider configuration of patterns at much cooler operating temperatures. There are many benefits to using this type of technology over conventional methods, because there are no pressurized gases stored within a glass bulb, and there is not any type of filament present. On average, their life expectancy is 10 to 100 times longer than other comparable light sources. There also is no mercury or other harmful elements contained within a LED spotlight fixture, so it is considered much safer for the environment when you choose one over a traditional type of spotlight.
When LED lighting first became popular in the 1960s, it was used on a variety of electronics for red indicator lights, and it was not until the mid-1990s when their full capabilities were realized. As their technology expanded to encompass more practical uses within our everyday lives, a number of industries switched to manufacturing this type of product as an economical alternative to incandescent lighting. LED spotlight technology has been implemented within televisions, flashlights, computers, holiday decorations and hundreds of other household items.
