Description
Product Overview
Designed specifically for UK light fixtures using the standard B22 bayonet cap, the Calex ST64 Warm Filament LED Bulb combines decorative vintage charm with efficient LED technology. Its teardrop gold-tinted glass casing houses straight LED filaments that emit a cosy 2100K warm white light at 250 lumens, turning the bulb into an attractive design element even when switched off.
Fully dimmable when paired with an LED-compatible trailing-edge dimmer switch, it allows you to adjust brightness seamlessly from soft ambient accent lighting to functional light. Suitable for home living rooms, bedrooms, or commercial venues like East London cafes, bars, and boutique hotels.
