Designed to replace grossly inefficient and desperately unreliable 40W filament light bulbs, this dimmable LED candle light bulb produces light of an equal quality and brightness but consumes just 5W in doing so.This remarkable efficiency - plus a rated lifetime of 15,000 hours - has the potential to yield savings of up to 88% when considering energy expenditure alongside maintenance and replacement costs.With a frosted finish and thermal plastic casing this LED candle dissipates heat more effectively than comparable materials, placing less strain on its components and thus extending its longevity even further.Recommended for Indoor lighting use only.
