Energizer 24.9W E27 LED GLS Bulb - 3452lm, 2700K Warm White, Non-Dimmable

The Energizer 24.9W LED GLS bulb is a high-output E27 Edison screw bulb delivering 3452 lumens at 2700K warm white, equivalent to a 200W halogen bulb. The GLS (General Lighting Service) shape makes it a direct replacement for traditional high-wattage bulbs in pendant fittings, ceiling roses, large table lamps and floor lamps where substantial light output is required. At 60mm diameter and 128mm height, it fits most standard lampshades and fittings designed for GLS bulbs.

Designed for living rooms, dining rooms, kitchens, hallways and commercial hospitality spaces where a single bulb needs to provide primary ambient lighting, the 3452-lumen output covers areas of 20-30m² comfortably. The 2700K colour temperature produces a warm, slightly amber-tinted white light similar to traditional incandescent bulbs, avoiding the cooler blue-white cast of daylight-temperature LEDs. The bulb is non-dimmable and operates on standard 230V UK mains, drawing 24.9W to achieve its full brightness.

The rated 15-year lifespan is based on average domestic use of 3 hours per day, equating to approximately 16,425 hours before the LED output degrades to 70% of its initial brightness. The bulb carries an Energy Rating of D under the updated 2021 EU energy label scale, which rates LEDs more strictly than the previous A++ scale. The solid-state LED design eliminates the warm-up period found in compact fluorescent bulbs, reaching full brightness instantly on switch-on.

Is this bulb dimmable?

No. This Energizer LED bulb is non-dimmable and must be used on standard on/off switched circuits. Fitting it to a dimmer switch may cause flickering, buzzing or premature failure.

What size room does 3452 lumens suit?

3452 lumens comfortably lights a room of 20-30m² as primary ambient lighting. For reference, that covers a typical 5m x 5m living room or a 4m x 6m kitchen-diner when the bulb is ceiling-mounted.

Will it fit my existing lampshade?

The bulb measures 60mm diameter and 128mm height, matching the dimensions of a standard GLS bulb. It fits most E27 pendant fittings and lampshades designed for traditional bulbs. Check your shade's internal clearance if it's particularly narrow or shallow.

How does the 15-year lifespan work?

The 15-year rating assumes 3 hours of use per day, totalling approximately 16,425 hours. The LED will continue to function beyond this point but brightness gradually reduces to around 70% of the original output.
