LED bulbs are grouped together in clusters and installed with diffuser lenses to magnify luminosity. This new technology broadened LED's applications in homes and even outside the home settings. With LED technology advancing ever so rapidly, new bulb styles, shapes, and sizes are emerging, each offering even greener alternatives that help save energy and the environment. While LEDs are initially more expensive than other light bulbs, the offer greater value as they last the longest, with average duty cycles of up to 50,000 hours or even longer.
Savings don't only come from the bulb's energy efficiency, as LEDs offer superior brightness and radiance in all kinds of applications. Unlike hot-running halogen and incandescent bulbs, cold-running LEDs never burn out, which means less frequent replacement. Despite them sometimes costing several times as much as other types of bulbs initially, savings come by the hundreds of pounds every year following purchase and installation. The upfront higher cost is nothing compared to the return on investment and financial savings you will get in the years to come.
This said it pays to purchase your LED bulbs from trustworthy suppliers and authorized dealers of established LED light brands like CREE, BridgeLux, and Epistar. With the constantly evolving LED technology, you should also turn to expert distributors that can give you sound advice on which types of bulbs to use for your specific applications, thus giving you more savings in the long run.
Additionally, LEDs are semi-conductors, a quality that makes old-fashioned incandescents and other light bulbs, along with energy-saving fluorescents look many times less efficient. A 4W LED replacement can produce the same level of light as a typical 35W-halogen bulb, which is still considerably less than the 10 watts that CFLs use.
LEDs offer the advantage of instant full light as they don't require a warm-up to start working, unlike their halogen and CFL counterparts. Today, LEDs can be found in a wide range of different 'warm' colours, in addition to the usual white light, which has been criticised for its 'cold' temperature.
