In stock
The Factorylux Short Tube Bulbs have an attractive and intricate long coil filament which spirals down the central glass stem. Factorylux incandescent light bulbs have been made in Switzerland since 1906 and have best in class aesthetics and longevity. Features:
  • extended lifespan - 5,000 hour average life
  • suitable for decorative use in pendant, wall, floor and table light fittings
  • seven perfectly formed filament spirals held in place by dozens of support wires
  • excellent colour rendition (CRI 100) and warm colour temperature (2,700K)
  • standard screw (E27 or ES) and standard bayonet (B22 or BC) cap options, both in 60 and 40 Watt versions
  • watch how the filaments are threaded by hand here
Dimming the bulbs greatly extends their life, creates a gorgeous yellow/orange sunset glow and hugely reduces energy consumption. The same coiled filament style is also available in the Oval Bulb or for a longer glass there's the Long Tube Filament Bulb.
