Description

The Energizer 9.5W LED GLS bulb fits a standard E27 Edison screw socket and produces 1050 lumens at 6500K daylight colour temperature, equivalent to a 75W halogen bulb. The GLS (General Lighting Service) shape is the classic A60 pear-shaped bulb profile that fits most table lamps, pendant fittings, and ceiling fixtures designed for traditional bulbs.

The 6500K colour temperature replicates natural midday sunlight, providing high-contrast visibility that suits task-focused environments such as home offices, workshops, kitchens, garages, and study rooms. The cool-white light renders colours more accurately than warm-white bulbs and reduces the yellow cast that can cause eye strain during detail work or screen-based tasks.

The bulb operates on 230V mains power and draws 9.5W to produce 1050 lumens, offering an efficacy of approximately 110 lumens per watt. The 240-degree beam angle provides wide, even distribution across a room rather than a focused spot. The non-dimmable design means the bulb switches straight to full output when powered on and maintains consistent brightness without flicker. Energizer rates the lifespan at 15 years based on average domestic use of 3 hours per day.

The bulb measures 109mm in height and 60mm in diameter, fitting standard lampshades and pendants without clearance issues. The frosted finish diffuses the LED chip array inside the bulb, preventing visible hotspots and giving a softer appearance when viewed directly. Energy rating E indicates moderate efficiency within the revised EU energy label scale introduced in 2021.

Frequently Asked

Is this bulb dimmable?

No. This bulb is non-dimmable and should not be used with dimmer switches. Installing a non-dimmable LED on a dimmer circuit can cause flicker, buzzing, or premature bulb failure.

What's the difference between 6500K and warm white?

6500K is daylight colour temperature, replicating midday sunlight with a cool, blue-white tone that enhances contrast and visibility for task lighting. Warm white (2700K-3000K) has a yellow-orange tone that creates ambient, relaxing light. Choose daylight for workspaces and warm white for living rooms and bedrooms.

How long does this bulb last?

Energizer rates the bulb at 15 years lifespan based on 3 hours of daily use, which equates to approximately 16,425 hours. Actual lifespan depends on operating conditions and how frequently the bulb is switched on and off.

Will this fit my existing lamp or fitting?

The bulb fits any fixture with an E27 (Edison screw) socket, which is the standard large screw fitting in the UK for table lamps, pendant lights, and ceiling fittings. The 109mm height and 60mm diameter match traditional GLS bulb dimensions, so it fits most shades and enclosures designed for standard bulbs.
