Description

The Energizer 9.5W GLS LED bulb uses a B22 bayonet cap fitting and delivers 1050 lumens at 4000K cool white, replacing a traditional 75W incandescent bulb whilst drawing just 9.5W. The non-dimmable LED driver provides consistent output without flicker, making it suitable for task lighting, utility areas, and spaces requiring steady, bright illumination.

Designed for residential and commercial applications, the bulb fits standard B22 lamp holders in ceiling pendants, wall lights, table lamps and floor lamps. The 4000K colour temperature sits between warm white and daylight, providing a neutral tone that works in kitchens, bathrooms, hallways, offices and workshops where clear visibility matters more than atmospheric warmth. The GLS (general lamp service) shape maintains compatibility with most lampshades and diffusers.

Rated E for energy efficiency under current UK regulations, the bulb uses approximately 87% less energy than the 75W incandescent it replaces. The B22 bayonet base locks securely into the lamp holder with a quarter-turn, reducing the risk of loose connections that cause flickering or intermittent contact. Energizer rates the bulb for a 15-year lifespan based on average domestic use of 3 hours per day.

Frequently Asked

Is this bulb dimmable?

No. The LED driver is non-dimmable and must not be used with dimmer switches, as this can cause flickering, buzzing or premature failure. Use only in standard on/off switched circuits.

What does 4000K cool white look like?

4000K sits between warm white (2700-3000K) and daylight (5000-6500K), producing a neutral white light without the yellow cast of warm bulbs or the blue tint of daylight. It's often described as a crisp, clean white that enhances visibility without altering colour perception significantly.

What is a B22 base?

B22 is the standard UK bayonet cap with two pins on the side of a 22mm diameter base. The bulb pushes into the lamp holder and locks with a quarter-turn twist, rather than screwing in like an E27 Edison screw base.

Can this replace a 60W incandescent?

This bulb is rated as a 75W incandescent replacement at 1050 lumens. For a 60W incandescent replacement (around 700-800 lumens), consider a lower-wattage LED in the 6-8W range.
