This Osram dimmable 4.8W LED candle light bulb replaces traditional 40W incandescent light bulbs. This LED candle is also known as a C35 due to its 35mm diameter.For those of you already lamenting the demise of these incandescent light bulbs - never fear. Their enduring popularity led to a new range of energy efficient LED equivalents.This LED candle light bulb combines form and function equally with the same gorgeous, retro styling no longer stymied by the restraints of outdated filament technology.The tungsten filaments found in these older light bulbs have now given way to four LED filaments, resulting in a gorgeous, traditional aesthetic that belies the light bulb's ultra-modern specification. These filaments, albeit similar in appearance, are much more efficient and robust than their traditional counterparts. Where a traditional light bulb might use approximately 40W to produce 470 lumens, these modern LED candle light bulbs use just 4.8W. This - coupled with the light bulb's vastly superior nominal lifetime of 15,000 hours - has the potential to reduce lighting bills by up to 90%.The light bulb's standard candle shape and SES-E14 small Edison screw (14mm) cap enable the light bulbs to retrofit directly to any existing fitting designed to accept light bulbs.
