The Sunset Dim Candle, B15 puts the classic candle shape on a small bayonet cap, warm-down glow included. Dimmable, it runs on 4.8 watts for 470 lumens of 2700K warm white in place of a traditional 40W incandescent, dropping to a deep 1800K amber at the low end. Ultra-high colour accuracy holds colours and textures true throughout, and the B15 small bayonet cap seats with a firm push and twist that stays put. Backed by a 3-year warranty.The Clear Glass EffectClear glass shows the filament, and that is where the candle gets its warmth and glint. A slim run of LEDs glows softly up the centre of the bulb, catching the light off nearby glass and metal, and leaving a tidy vintage look when it is switched off. That makes it a natural in open and wall-mounted fittings where the candle is on show. Behind a shade, or where you would rather a diffused glow with no filament, the Porcelain candle avoids the shadows a clear bulb can throw on the fabric.It parts company with an ordinary LED candle as soon as you dim it. Rather than staying one tone, it warms toward amber on the way down, holding a soft, low glow instead of a cold one. On an LED-compatible dimmer the fade stays smooth.Where It BelongsThe B15 Candle suits fittings built around a small bayonet cap, where the push-and-twist keeps it secure. At home that is bayonet wall lights, bedside and buffet lamps, and smaller pendants and chandeliers wired for bayonet. In hotel, restaurant and function-room wall sconces and stairwells it helps set the mood, and the positive cap makes maintenance quicker. The B15 small bayonet cap twists into the smaller bayonet fittings found in wall lights, lamps and compact pendants.
