Energizer 9.5W LED GLS Bulb B22 Warm White 2700K Non-Dimmable

The Energizer 9.5W LED GLS bulb delivers 1050 lumens of warm white light at 2700K through a standard B22 bayonet cap fitting. The bulb draws 9.5W to produce the equivalent output of a 75W halogen, rated at 15,000 hours of operation or approximately 15 years at average domestic use. The GLS (General Lighting Service) shape is a classic A60 globe profile that fits the majority of UK ceiling pendants, table lamps and floor lamp fittings.

Designed for general ambient lighting in living rooms, bedrooms, hallways and dining rooms, the 2700K colour temperature produces a warm, yellowish-white tone similar to traditional incandescent bulbs. The 240-degree beam angle distributes light widely across a room rather than creating a focused spot, making the bulb suitable for central ceiling positions and multi-arm chandeliers where even spread is needed. The B22 bayonet cap is the standard UK domestic fitting and installs by pushing and twisting into the lamp holder.

The bulb measures 60mm diameter by 109mm height, which is within the typical GLS envelope size and fits inside most lampshades and enclosed fittings without clearance issues. The frosted glass diffuser softens the LED chip array inside, preventing visible point-source glare when the bulb is viewed directly. The bulb is non-dimmable and operates on 230V mains voltage without requiring a transformer or driver.

Energizer rates the bulb with an E energy rating under the revised 2021 EU energy label scale (which runs from A to G, with A being most efficient). The 9.5W consumption at 1050 lumens gives a luminous efficacy of 110 lumens per watt, which is standard for contemporary LED GLS bulbs in this output bracket.

Is this bulb dimmable?

No. This Energizer bulb is non-dimmable and operates at full 1050-lumen output when switched on. Attempting to use it with a dimmer switch may cause flickering, buzzing or premature failure. For dimmable alternatives, search for Energizer or other brands' dimmable LED GLS bulbs with B22 caps.

What does 2700K warm white look like?

2700K produces a warm, yellowish-white light similar to traditional incandescent and halogen bulbs. It creates a relaxed, homely atmosphere and is the standard colour temperature for living rooms, bedrooms and dining rooms. It contrasts with cooler 4000K or 6500K whites which appear bluer and are typically used in kitchens, bathrooms and task lighting.

What is the lifespan of this bulb?

Energizer rates this bulb at 15,000 hours, which equates to approximately 15 years of use at an average of 2.7 hours per day. Actual lifespan varies depending on operating conditions, switching frequency and ambient temperature.

Will it fit my existing B22 lamp holder?

Yes. The B22 bayonet cap is the standard UK domestic fitting and is compatible with the majority of UK ceiling pendants, table lamps, floor lamps and wall lights. The 60mm diameter and 109mm height are within the typical GLS envelope size, so the bulb should fit inside most lampshades and enclosed fittings without clearance issues.
