The first Filament LED light bulbs came on the market around three years ago. As with most technologies, there were significant initial problems with faults and performance, particularly in relation to dimming, flicker, colour temperature and render, and life-span. A significant amount of work has been done to overcome the problems and the technology is now mature enough for Factorylux to launch its first two LED-Filament light bulbs - the LED-Filament Pear and the LED-Filament Large Globe.

|---|---|
| traditional glass envelope and stem | A+ energy rating |
| classic pear and large globe shapes | 470 lumen for the pear/620 for the globe |
| exceptionally narrow LED filaments | colour render > 90 CRI |
| LEDs emit light around filaments | colour temperature 2,200K |
| 8 filaments for even light distribution | full brightness in < 0.1 s |
| no 'striping' or 'banding' effects | 20,000 hour life for the pear/25,000 for the globe |
| dimmable to <1% brightness | 100,000 switching cycles |
| driver fully integrated in cap | power factor > 85% |
Factorylux LED-Filament Large Globe (left) v Factorylux Tungsten Filament Large Globe (right)Factorylux LED-Filament bulbs are the first LEDs to challenge the performance of tungsten filament in terms of aesthetics, colour render and colour temperature. And they use up to 90% less energy than traditional filament bulbs. The LED-Filament Pear is £17.40 (inc VAT) and the LED-Filament Large Globe £21.60 (inc VAT and delivery). The overall running cost is under 0.21 pence/hour based on the rated 25,000 hour life and the average UK domestic energy cost of 30 pence/kWh. Factorylux LED-Filament light bulbs open a new chapter for decorative lighting in the home, leisure and retail.
