Description
The Knightsbridge 8W LED GLS filament bulb uses visible LED filament strips inside a clear glass envelope to replicate the appearance of a traditional 60W incandescent lamp while delivering 1120lm at 2700K warm white. The E27 (Edison screw) base fits standard UK lamp holders in table lamps, floor lamps, pendants and ceiling fittings where the bulb is visible or where a warm filament glow is preferred over enclosed LED modules.
Designed as a direct replacement for 65W incandescent GLS bulbs, the 8W LED provides comparable light output at substantially lower energy consumption and longer operational life. The L70B50 rating of 15,000 hours means the bulb retains 70% of its initial brightness after 15,000 hours of use, equivalent to approximately 10 years at 4 hours per day. The 330° beam angle distributes light in all directions bar the screw cap end, making it suitable for open fixtures, table lamps and pendants where omnidirectional light spread is needed.
The bulb is dimmable when paired with compatible trailing edge dimmers — check dimmer compatibility before installation as performance varies between dimmer models. The clear glass envelope and visible filament strips give the bulb a decorative quality when lit, showing warm amber light through the glass rather than the stark white appearance of concealed LED chips. The 60mm diameter and 105mm overall height match standard GLS bulb dimensions, so the fitting proportions remain consistent when replacing existing incandescent or halogen bulbs.

Frequently Asked
Is this bulb dimmable?
Yes, but compatibility depends on the dimmer model. The bulb works with most trailing edge dimmers but performance varies. Test with your existing dimmer or contact us for confirmed compatible models before installation to avoid flickering or reduced dimming range.
What incandescent wattage does this replace?
This 8W LED delivers 1120lm, comparable to a 65W incandescent GLS bulb. The warm white 2700K colour temperature matches the tone of traditional tungsten filament lamps.
Can it be used in enclosed fittings?
The IP20 rating means the bulb is suitable for indoor dry locations only. It can be used in semi-enclosed fittings where some ventilation exists, but avoid fully sealed fixtures where heat buildup may reduce lifespan.
How long does the bulb last?
The L70B50 rating of 15,000 hours means the bulb retains 70% of its original brightness after 15,000 hours of operation. At 4 hours per day, that equates to approximately 10 years of use before noticeable dimming occurs.
