This dimmable 14W LED GLS light bulb from Osram combines a robust exterior shell with modern LED technology to deliver durability and efficiency in equal measure. Features a ES-E27 Edison screw (27mm) base/cap. Also known as an A60 light bulb.A slightly larger GLS shape with a frosted finish and ES/Edison Screw cap make it a perfect retrofit replacement for traditional filament light bulbs. However, despite the shared aesthetics, this LED light bulb uses completely different technology which allows it to produce the same bright, warm white light as a 100W incandescent light bulb, while in reality consuming just 14W. This represents a substantial energy saving that can reduce your lighting bill by up to 90%.The light bulb\'s excellent build quality fortifies it against vibrations and equips it for use in lower temperatures. This lends it an extra level of versatility that makes it perfect for a range of commercial and domestic applications alike, including outdoor environments (providing it is used in a luminaire with an adequate IP rating).Please visit the manufacturer\'s website for up-to-date dimmer switch compatibility lists for this Osram LED GLS light bulb before purchase.To find the answers to some common questions about LED dimming, please read our guide Dimming for Dummies.Need more help in choosing a suitable light bulb?
