Energizer 5W LED PLS 2-Pin Bulb 2G7 - Cool White 4000K Non-Dimmable

The Energizer 5W LED PLS is a twin-tube 2-pin bulb with a 2G7 base, delivering 580 lumens at 4000K cool white. It replaces 11W compact fluorescent PLS bulbs in downlights, bathroom mirror fittings, display cabinets and commercial installations that use twin-tube compact fluorescent luminaires. The 2G7 base is a push-fit 2-pin connector spaced at 7mm, common in UK commercial and residential compact fluorescent fittings from the 1990s onwards.

Designed for utility and commercial spaces where cool white light is needed for task work or general illumination, the 4000K colour temperature sits between warm white and daylight, providing neutral clarity without the yellow cast of 3000K bulbs or the clinical feel of 6000K. The bulb fits vertically or horizontally oriented PLS luminaires in offices, schools, retail displays, storage areas, and bathroom mirror lights. The non-dimmable LED driver provides fixed output on standard 230V mains, removing the flicker associated with ageing fluorescent ballasts.

The twin-tube configuration measures approximately 104mm in length from the base to the tube ends, with a 15mm tube diameter. Energy rating D under the new 2021 EU labelling regulations reflects typical efficiency for compact LED retrofits of this form factor. The 30,000-hour rated lifespan reduces maintenance frequency compared to fluorescent equivalents, which typically need replacement every 8,000-10,000 hours in commercial use.

Can this replace my existing 11W compact fluorescent PLS bulb?

Yes, if your existing bulb has a 2G7 2-pin base and twin-tube PLS configuration. The Energizer 5W LED provides equivalent light output to an 11W compact fluorescent but at lower wattage. Check that your luminaire is compatible with LED retrofit bulbs, as some older fittings with magnetic ballasts may need the ballast bypassed or the luminaire replaced.

Is the bulb suitable for bathroom mirror lights?

Yes, provided the fitting is suitable for LED retrofit and the luminaire has appropriate IP rating for bathroom use. The 4000K cool white output provides good colour rendering for grooming tasks. The bulb itself is not IP-rated, so it must be installed inside a suitably rated enclosed luminaire for bathroom zones.

What's the difference between 4000K and 3000K?

4000K cool white produces a neutral, slightly blue-toned light that suits task-focused environments like offices, kitchens and retail displays. 3000K warm white has a yellow-orange tone closer to traditional incandescent bulbs, typically preferred in living rooms and bedrooms. 4000K is often described as 'office white' or 'clean white'.

How long does the bulb last?

Energizer rate this LED bulb for 30,000 hours, which translates to approximately 13-15 years at 6 hours daily use, or 6-8 years in commercial settings running 12 hours per day. This is roughly three times the lifespan of equivalent compact fluorescent bulbs.
