Ferrowatt Large Tesla Vintage Bulb (LB3)
Ferrowatt Vintage Large Tesla Lamp 40w E26 base. Ferrowatt produce museum quality carbon filament lamps for films and heritage sites. Our range of filament bulbs are recreated using modern incandescent filaments to recreate the appearance of the carbon versions, however they produce significantly more lumens. The Squirrel cage mimics the method used in early light bulb production where the cage was used to add more filaments to gain more light. These bulbs are for use for aesthetic appearance.
