Energizer 18W LED GLS Bulb E27 6500K Daylight - Non-Dimmable 2542lm

The Energizer 18W LED GLS bulb produces 2542 lumens of 6500K daylight-temperature light from a standard E27 Edison screw base. Rated as a 150W halogen replacement, the bulb draws 18W on 230V mains and delivers a crisp, cool-white output suited to task lighting rather than ambient warmth. The GLS (General Lighting Service) shape matches the profile of traditional incandescent bulbs, fitting standard table lamps, ceiling pendants and bare-bulb fittings without adapter rings.

Designed for kitchens, home offices, workshops and utility rooms where clear visibility matters more than atmosphere, the 6500K colour temperature replicates natural midday light and improves colour rendering for detail work, food preparation and reading. The non-dimmable circuitry provides consistent full brightness from switch-on and avoids the compatibility issues that arise when pairing dimmable LEDs with older dimmer switches. The bulb is rated for up to 15 years of typical household use at 3 hours per day.

The frosted glass envelope diffuses the internal LED array to eliminate visible point sources and reduce glare when the bulb is installed in an open fitting. At 2542 lumens the output is substantially brighter than most domestic ceiling lights, making this bulb well-suited to larger rooms or spaces with high ceilings where a single central fitting must cover 15-20m². The E27 base fits UK, European and most global domestic lighting circuits rated for 230V AC.

Is this bulb dimmable?

No. The bulb is non-dimmable and will provide full brightness when switched on. Attempting to use it with a dimmer switch may cause flickering, buzzing or early failure.

What does 6500K daylight mean?

6500K is a cool-white colour temperature that replicates natural daylight at midday. It produces a crisp, slightly blue-toned light that improves visibility and colour rendering, making it well-suited to kitchens, workshops and offices. For warmer, more ambient lighting in living rooms or bedrooms, a 2700K-3000K bulb would be more appropriate.

How bright is 2542 lumens?

2542 lumens is equivalent to a traditional 150W incandescent bulb and is substantially brighter than most domestic ceiling lights. This output suits larger rooms, high ceilings or spaces where a single central fitting must provide all the light.

What is the rated lifespan?

Energizer rates this bulb for up to 15 years based on typical household use of 3 hours per day. Actual lifespan depends on usage patterns and the number of on/off cycles.
