These energy efficient antique LED bulbs from Crompton Lamps are the perfect replacement for incandescent filament light bulbs that are no longer available in the UK.Designed to replicate the look and the light output of the familiar incandescent bulbs, these LED light bulbs offer the same brightness but use only a fraction of the power. The faithfulness of the design even extends to the filaments, which are shaped to look like the incandescent filaments they replace, but are much more robust and efficient. This 6W LED bulb is a direct replacement for a 25W incandescent filament bulb.These bulbs will add a touch of vintage style to any room, whether paired with a retro copper-effect lamp, or hung on their own as exposed bulbs. The bronze-effect finish adds to the bulb\'s antique style, and means that it offers a cosy 250 lumens of extra warm 2200K light. It can be dimmed to lower light when used with a compatible dimmer switch.. Unlike the filament bulbs it replaces, this LED bulb will last for years, with an average rated life of 15,000 hours. So as well as being one of the most stylish light bulbs available today, it is also one of the most efficient.B22d bayonet cap15,000 hour rated life7,500 switching cycles2200K extra warm whiteCompatible with both leading and trailing edge dimmersFor indoor use only3 year manufacturer warranty
