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 light 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 15,000 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 6W R63 Thermal Plastic LED reflector is designed to retrofit to existing Edison Screw/ES fixtures that can accommodate the light bulb\'s 63mm envelope. We find that the light bulb\'s opal finish and relatively wide beam angle of 120 make it particularly useful in singular fixtures (desk light bulbs etc.) or collectively as a diffuse light source in wall sconces or ceiling assemblies.Not suitable for dimming. Recommended for Indoor lighting use only. Features a ES-E27 Edison screw (27mm) base/cap.
