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 5.5W in doing so. This remarkable efficiency - plus a rated lifetime of 25,000 hours - has the potential to yield savings of up to 90% when considering energy expenditure alongside maintenance and replacement costs whilst simultaneously reducing carbon emissions. A frosted finish and thermal plastic shell encases the light bulbs and dissipates heat away from their components more effectively than existing materials, thereby extending their longevity even further. This results in a range of light bulbs that is reliable, green, elegant and easy to install. These dimmable LED candle light bulbs are compatible with both leading and trailing edge dimmers though full, industry-wide compatibility cannot be guaranteed. Also known as a C35 candle due to its 35mm diameter. Features a BC-B22d bayonet (22mm) cap base. Suitable for dimming. Recommended for Indoor lighting use only.
