Description

The Energizer 12.6W LED GLS bulb fits a standard B22 bayonet cap and delivers 1521 lumens at 2700K warm white, replacing a traditional 100W incandescent bulb while consuming 87% less energy. The GLS (General Lighting Service) shape is the classic pear-shaped bulb profile that fits most table lamps, ceiling pendants and standard household light fittings.

Designed for living rooms, bedrooms and dining areas where controllable ambient light matters, the bulb is fully dimmable when paired with compatible LED dimmer switches. Dimming allows the light level to be adjusted from full 1521lm output down to a low-level evening glow without flicker or hum. The 2700K colour temperature sits at the warmer end of the white spectrum, producing a soft yellow-toned light that flatters skin tones and wood finishes.

The bulb is rated for a 15-year lifespan based on 3 hours daily use, which translates to approximately 16,425 hours total runtime. The frosted glass envelope diffuses the internal LED array evenly, avoiding visible hotspots or striping when viewed directly. At 12.6W draw on 230V mains, the bulb runs cool enough to be safe in enclosed fittings and fabric shades where heat buildup from halogen or incandescent bulbs would be a concern.

Frequently Asked

Is this bulb dimmable?

Yes. The Energizer 12.6W GLS is fully dimmable when used with LED-compatible dimmer switches. Older trailing-edge dimmers designed for incandescent bulbs may cause flicker or incomplete dimming range — if in doubt, check your dimmer is rated for LED loads.

What does 2700K mean?

2700K is the colour temperature measured in Kelvin. It produces a warm white light with a soft yellow tone, similar to traditional incandescent bulbs. This is warmer than daylight (5000K+) and cooler than candlelight (1800K).

How long does the bulb last?

Energizer rates this bulb for a 15-year lifespan based on 3 hours daily use, which equates to approximately 16,425 hours of total runtime. Actual lifespan varies depending on usage patterns and operating environment.

Can it be used in enclosed fittings?

Yes. The 12.6W LED bulb runs cool enough to be used safely in enclosed ceiling fixtures, pendant shades and table lamp bases where heat from halogen or incandescent bulbs would otherwise build up and shorten bulb life.
