Value pack of 5.As the move towards LED technology and away from old-fashioned incandescents gathers pace, the benefits of doing so are becoming more and more obvious. Superior efficiency, longevity and versatility have all become hallmarks of LED technology and nowhere is this typified more than the new range of Thermal Plastic LED R63/R64 Reflectors from Crompton light bulbs.This range of ultra modern LED R63/R64 Reflectorlight bulbs uses a lightweight exterior shell to both house the light bulb\'s components and dissipate any heat away from them much quicker and more effectively than the aluminium heat sinks of other LED light bulbs. In doing so, this places them under less strain and enables the light bulb to last much longer, thereby minimising the number of times it would need to be replaced; for many, the 20,000 hour rated lifetime would be enough to avoid replacement costs altogether.LED light bulbs use up to 90% less energy than incandescent versions and can conceivably reduce your lighting bill by a similar amount. Pair this with their reduced replacement costs and you can begin to get a measure of just how much each light bulb can save (both in terms of energy consumption and subsequent bill payments).This 8W R63 reflector is designed to retrofit to existing Small Edison Screw/SES fitments that can accommodate the light bulb. We find that the light bulb\'s opal finish and relatively wide beam angle of 110 make it particularly useful for diffused lighting either on its own in desk light bulbs and other restrictive fixtures, or collectively in wall sconces or ceiling assemblies. Features a commonly used ES-E27 Edison screw (27mm) cap/base.This R63/R64 Reflector is a newer product from Crompton Lamps and supercedes their old R63/R64 Reflector part codes: 6652, 3965, LEDR64ES7WW, ER6442DES, PR6440DES, PR6460DES.
