The elegant filament design and E27 screw cap ensure easy installation in pendants, lamps, or ceiling fittings.

About Bell Lighting: A British, family-run brand since 1920, BELL Lighting combines classic design with LED innovation, proudly based in West Yorkshire. This product works best with LED-rated trailing-edge dimmers, as older leading-edge types may be incompatible. To size correctly, simply divide your dimmer’s minimum and maximum range by 10 to find the suitable LED range (for example, a 100–300 W dimmer corresponds to 10–30 W total LED load). Be sure to keep your total LED wattage within this range to avoid flickering or buzzing, and adjust away from extreme dimmer settings if necessary. Please note that it is not compatible with 3-way touch control lamps. For assistance, you can check our dimmer compatibility list or contact us anytime.

Warm white 2700K light with CRI 85, 470 lumens output from 4.5W, dimmable for flexible lighting and only suitable for dimmable fittings; performance may vary depending on dimmer compatibility. For best results, use with trailing edge LED-compatible or modern electronic dimmers. Using incompatible dimmers may cause flickering or limited dimming range.
