Energizer 24.9W LED GLS Bulb B22 Warm White 2700K Non-Dimmable

The Energizer 24.9W LED GLS bulb delivers 3452 lumens of warm white 2700K light through a standard B22 bayonet cap fitting, replacing a 200W incandescent bulb while using 87% less energy. The GLS (General Lighting Service) shape matches traditional bulb profiles, fitting standard lampholders and shades without adapters or modifications.

Designed for living rooms, bedrooms, hospitality reception areas and dining spaces where warm ambient light is needed, the bulb produces enough output to serve as a primary light source in rooms up to 20-25m². The B22 bayonet fitting installs by pushing and twisting into UK standard lampholders found in ceiling pendants, table lamps and floor lamps. The bulb is non-dimmable and operates on mains 230V power without requiring external drivers or transformers.

The 2700K colour temperature sits at the warmer end of the white spectrum, producing light with a slight amber cast that resembles traditional tungsten bulbs. This makes the bulb well-suited to residential settings where cooler white tones would feel clinical. The rated 15-year lifespan assumes 3 hours daily use, translating to approximately 16,400 hours of operation before output drops below 70% of initial lumens.

Energizer rates this bulb at Energy Rating D under current UK/EU labelling, placing it in the mid-range of current LED efficiency standards. The frosted glass envelope diffuses the internal LED array to eliminate visible point sources and produce even light distribution across the full 360-degree output pattern typical of GLS bulbs.

Is this bulb dimmable?

No. The Energizer 24.9W GLS is non-dimmable. Installing it in a circuit with a dimmer switch may cause flickering, buzzing or premature failure. Use only with standard on/off switches.

What is the B22 base type?

B22 is the UK bayonet cap fitting with two pins that lock by pushing and twisting. This is the standard bulb fitting for most UK ceiling lights, table lamps and floor lamps manufactured for the British market.

How bright is 3452 lumens?

3452 lumens is equivalent to a traditional 200W incandescent bulb. This output suits medium to large living rooms, dining rooms or open-plan kitchen-diners as a primary ceiling light, or smaller spaces where very bright ambient light is needed.

What does 2700K warm white look like?

2700K produces light with a warm amber-white tone similar to traditional tungsten bulbs. It appears noticeably warmer and more yellow-toned than daylight (5000K+) or cool white (4000K) LEDs, making it better suited to residential interiors than offices or commercial settings.
