Description
This is a classic GLS bulb in opal glass, the familiar rounded pear shape most of us picture when someone says light bulb, with an E27 screw cap at its base. It is 10.5cm long and 6cm across, a size worth checking against the lampshade or fitting you have in mind. Inside, LEDs draw just 3.8W and give 806lm of warm white light at 2700K, and the opal glass spreads that output into a soft, even glow with no bright hotspot. It is rated IP20, which settles where it goes: indoors, in dry rooms.
Our opal GLS bulb suits the places where you want a gentle, familiar warmth: a table lamp in the living room, a bedside light, a pendant over the dining table or a hallway light that comes on every evening. Warm white at 2700K sits at the cosy end of the scale, so rooms feel welcoming rather than clinical. Because the glass is opal rather than clear, it is a good choice for open shades and bare pendants, where the bulb itself is on show and a soft, diffused face matters. With energy class A and a draw of only 3.8W, it is an easy bulb to leave burning through a long winter evening.
The bulb runs on a 220-240V, 50/60Hz mains supply, the ordinary household voltage. It is not dimmable, so choose it for a lamp or light on a plain on and off switch and keep it away from any circuit controlled by a dimmer. The packed weight is 0.079KG. To clean the glass, wait until the bulb is cold and unpowered, then wipe it gently with a soft, dry cloth. As a practical note, keep a spare in a kitchen drawer so a favourite lamp is never left dark for long.
