Energizer 5W LED PLS/E 2G7 4-Pin Bulb - 4000K Cool White 700lm Non-Dimmable

The Energizer 5W LED PLS/E is a compact fluorescent replacement bulb with a 2G7 4-pin base, delivering 700 lumens at 4000K cool white. The twin-tube PLS/E form factor measures approximately 136mm in total length and fits directly into existing commercial and residential fittings originally designed for 11W compact fluorescent lamps, including slimline wall lights, emergency exit signs, under-cabinet task lights and bathroom mirror cabinets.

Designed for areas where crisp, neutral-white task lighting is needed, the 4000K output sits between warm domestic white (2700K-3000K) and daylight white (5000K-6500K), making it suitable for office environments, healthcare waiting areas, retail display shelving, workshops and utility rooms. The bulb is non-dimmable and operates on standard 230V mains via the ballast or driver built into the host fitting.

The 2G7 base has four pins arranged in two pairs, one pair at each end of the twin-tube assembly. This configuration locks the bulb into the socket with a quarter-turn twist, preventing accidental removal during cleaning or maintenance. At 5W draw the bulb consumes approximately 55% less energy than the 11W fluorescent it replaces while producing comparable light output, rated energy class D under current UK labelling regulations.

Energizer LED bulbs carry a 30,000-hour rated lifespan at typical usage patterns, reducing relamping frequency in commercial installations where access requires ladders or scaffolding. The solid-state LED construction is more resistant to vibration and thermal shock than fluorescent tubes, making it better suited to high-traffic areas and fittings subject to frequent on-off cycling.

Will this fit my existing 2G7 fitting?

Yes, provided the fitting was originally designed for a 2G7 4-pin compact fluorescent lamp. The bulb is a direct retrofit and requires no rewiring. Some older electronic ballasts may need replacing with LED-compatible drivers — check the fitting manufacturer's guidance if the bulb flickers or fails to light.

What does 4000K cool white look like?

4000K is a neutral white tone that sits between the warmer yellows of domestic lighting (2700K-3000K) and the bluer daylight tones (5000K+). It provides good colour rendering for task work without the clinical harshness of pure daylight white, making it popular in offices, healthcare and retail.

Can I use this bulb on a dimmer switch?

No. The bulb is non-dimmable and will not function correctly with dimmer switches or variable control systems. Attempting to dim a non-dimmable LED can cause flickering, premature failure or damage to the dimmer circuit.

How does the 2G7 base differ from other compact fluorescent bases?

The 2G7 base has four pins arranged in two pairs, one at each end of the twin-tube assembly. This differs from 2-pin G23 or GX23 bases (single-ended) and 4-pin 2G11 bases (linear tubes). The pin configuration is unique to 2G7, so the bulb will not physically fit other base types.
