The filament in this oval bulb coils down the central glass stem to create a strikingly attractive and intricate lamp. Factorylux filament bulbs have been hand made in Switzerland since 1906 and have exceptional aesthetic qualities. Features:
  • unsurpassed lifespan - 5,000 hour average life

  • faithful colour rendition (CRI 100) and warm colour temperature (2,700K)

  • suitable for decorative use in pendant, wall, floor and table light fittings

  • the tungsten filament - held by dozens of support wires - spirals down the glass stem seven times

  • standard screw (E27 or ES) and standard bayonet (B22 or BC) cap options, both in 40 and 60 Watt versions

Dimming the bulb allows the beauty of the spiral filament to be fully appreciated, greatly extends the life of the bulb and hugely reduces energy use. The same filament style is available in the Factorylux Short Tube Filament Bulb.

Fast delivery and a quality product. Review by Chris Originally chose the 40w but found it a little too dim for our lounge, swapped for the 60w which has worked a treat. Fast delivery and a quality product. (Posted on 15 January 2018)
