Energizer 9.5W LED GLS Bulb B22 Daylight 6500K Non-Dimmable - 1050lm

The Energizer 9.5W LED GLS bulb is a B22 bayonet-cap LED delivering 1050 lumens at 6500K daylight colour temperature. The 9.5W LED replaces a traditional 75W incandescent bulb while drawing significantly less power, and the GLS (General Lighting Service) shape fits standard UK lamp holders in ceiling pendants, table lamps and wall lights.

Designed for spaces where high colour accuracy and visibility matter, the 6500K daylight output suits kitchens, home offices, workshops, garages and bathrooms where tasks like food preparation, reading, close work or grooming benefit from cooler, neutral white light. The 240-degree beam angle provides broad room coverage from a single ceiling fitting. The bulb is non-dimmable and rated for 15,000 hours of operation, equating to approximately 15 years at typical household usage of 2.7 hours per day.

The frosted glass envelope diffuses the LED elements evenly across the bulb surface, preventing glare and creating a consistent light distribution across the room. At 60mm diameter and 109mm height, the bulb fits most GLS-compatible shades and fittings without protruding. The B22 bayonet cap twists and locks into UK bayonet holders without requiring screw threads, allowing quick bulb changes in hard-to-reach ceiling fittings.

Energizer rates this bulb at Energy Rating E under current UK energy labelling standards. The 1050-lumen output at 9.5W gives approximately 110 lumens per watt, which is competitive within the non-dimmable LED GLS category. The bulb operates on 220-240V mains without requiring a transformer or separate driver.

What incandescent wattage does this replace?

The 9.5W LED produces 1050 lumens, equivalent to a traditional 75W incandescent bulb. The packaging confirms this as a 75W replacement.

Is the 6500K colour temperature suitable for living rooms?

6500K is a cool daylight tone that most users prefer in task-focused areas like kitchens, bathrooms, offices and workshops rather than living rooms or bedrooms. For relaxation spaces, a 2700K-3000K warm white bulb is typically more comfortable. Daylight bulbs work well where you need clear visibility for detailed work.

Can this bulb be used with a dimmer switch?

No. The bulb is rated non-dimmable and will not function correctly with dimmer switches. Attempting to use it on a dimmer circuit may cause flickering, buzzing or premature failure. If dimming is required, choose a dimmable-rated LED bulb instead.

What is the expected lifespan?

Energizer rates this bulb at 15,000 hours, which translates to approximately 15 years at an average household usage rate of 2.7 hours per day. Actual lifespan will vary depending on how frequently the bulb is switched on and off and the ambient temperature of the fitting.
