Energizer 24W LED PLL 4-Pin Bulb - G23, 4000K Cool White, 3200lm

The Energizer 24W LED PLL is a 4-pin plug-in bulb with a G23 base, delivering 3200 lumens of cool white light at 4000K. The PLL (parallel linear) format features two parallel tubes joined at the base, creating a long light-emitting surface that distributes brightness evenly across the length of the bulb. This LED version replaces traditional 55W CFL PLL tubes in existing fixtures without modification.

Designed for commercial and industrial environments requiring continuous high-output lighting, the bulb suits corridors, offices, workshops, retail stockrooms and communal areas where light runs for extended periods. The 4-pin G23 base pushes into the socket and twists to lock, ensuring secure contact with the ballast or driver. The non-dimmable design simplifies installation in standard switched circuits.

The 4000K colour temperature produces a neutral cool white light that supports task visibility and colour accuracy in work environments. At 24W the bulb draws less than half the power of the 55W CFL it replaces while delivering comparable lumens, reducing running costs in multi-bulb installations. The LED construction extends lifespan significantly over fluorescent equivalents, lowering maintenance frequency in ceiling-mounted fixtures that require access equipment to service.

Energy rated E under current UK regulations, the bulb provides a direct retrofit path for facilities looking to transition fluorescent PLL fixtures to LED without replacing the entire fitting. The parallel tube configuration maintains the same form factor as CFL PLL bulbs, allowing the LED to fit the same reflectors and diffusers in the existing fixture housing.

Will this work in my existing PLL fixture?

The bulb fits G23 4-pin sockets used in standard PLL fixtures. Some older fixtures use magnetic ballasts that are incompatible with LED bulbs and will require a bypass or driver replacement. Check your fixture documentation or contact us with your fixture model to confirm compatibility before ordering.

What does 4000K cool white look like?

4000K sits between neutral white and daylight, producing a crisp, slightly blue-toned white light that supports concentration and colour accuracy in work environments. It appears cooler than the warm white used in residential lighting but less stark than 6000K+ daylight bulbs.

How does the lumen output compare to a 55W CFL?

A typical 55W CFL PLL tube produces 3200-3600 lumens. This 24W LED delivers 3200lm, matching the lower end of that range while drawing 56% less power. Actual brightness perception depends on the fixture's reflector and diffuser design.

Can this be used in enclosed fixtures?

LED bulbs generate less heat than CFLs but still require some airflow for thermal management. The bulb can be used in enclosed fixtures provided the fixture design allows some passive ventilation. Completely sealed housings may shorten bulb lifespan through heat buildup.
