Borrowing all the classic style and none of the power-hungry inefficiency from its namesake, these vintage styled filament bulbs have eco-tech in every millimetre. Highly efficient LED technology replaces the less economical original incandescent bulbs but keeps their retro styling and aesthetic right down to the coiled ‘filament’. Designed to look good and work brilliantly, these dimmable bulbs are each equivalent to a 25W incandescent light bulb and for further adaptability they can be used with a LED compatible dimmer switch. Choose from either white or amber light to accentuate your home and furnishings with steady, adjustable light that won’t cost the planet.
