  • renders colours faithfully (CRI 100) and warm colour temperature (2,700K)
  • suitable for decorative use in pendant, wall, floor and table light fittings
  • the tungsten filament is held in spirals by over 30 support wires

Dimming the Edison bulb reveals the complex beauty of the spiral filament, creates a relaxing orange/yellow sunset light and hugely reduces energy use. A longer version of the same filament style is available with the Oval Spiral and Short Tube Coil Filament Bulbs.
