The decorative range of MASTER LED candle light bulbs from Philips is designed to bridge the gap between traditional aesthetics and modern efficiency.The dimmable 4W option pictured here is designed to replace a 25W filament candle light bulb. It does so seamlessly, consuming a fraction of the power but producing an incandescent sparkling effect that is reminiscent of the original light bulb.With this in mind, it will retrofit directly to any existing SES-E14 small Edison screw (14mm) fixture; whether that be in large-scale commercial installations such as chandeliers or wall sconces, or in smaller domestic applications.The LED candle light bulb\'s unique design delivers a whole slew of benefits, from desirable aesthetics that work just as effectively when the light bulb is turned off, to excellent efficiency and even light distribution. The light bulb boasts a 25,000 hour rated lifetime and level of efficiency that is leagues ahead of the incandescent light bulbs that came before it (in some cases reducing lighting bills by up to 90%) - all in a package that looks just as good, if not better, than those it is intended to replace.240V 4W (25W equivalent) LED CandleSES-E14 capYes - Dimmable250 lumens
