Description

The Knightsbridge 4W LED candle filament bulb uses visible LED filament strips inside a clear glass candle envelope to replicate the appearance of a traditional incandescent lamp while delivering modern LED efficiency. The E27 Edison screw base fits standard lamp holders and the 35mm diameter candle shape suits exposed-bulb wall lights, chandeliers, and decorative fittings where the bulb is visible.

Designed as a direct replacement for 40W incandescent candle bulbs, the 4W LED delivers 485 lumens at 2700K warm white colour temperature, giving the same warm ambient light as the older lamp technology at a fraction of the energy draw. The bulb is dimmable when paired with compatible trailing-edge dimmers, allowing brightness to be adjusted from full output down to approximately 10% for mood lighting in dining rooms, living rooms and bedrooms.

The clear glass envelope and exposed filament strips give the bulb a decorative quality when lit and unlit, making it suitable for use in open-shade fittings and traditional-style chandeliers where the bulb itself contributes to the aesthetic. The 15,000-hour L70B50 rating means the bulb retains at least 70% of its initial light output after 15,000 hours of use, equivalent to approximately 13 years at three hours per day.
