Description

The Energizer 18W LED PLL is a 2G11 4-pin bulb delivering 2250 lumens at 4000K cool white, designed to replace older 36-40W CFL PLL lamps in commercial ceiling fixtures, retail panels and utility areas. The 2G11 base is a 4-pin plug-in fitting common in recessed ceiling panels, under-cabinet lighting and display case installations where the ballast is integrated into the fixture rather than the bulb.

This bulb is non-dimmable and rated at 18W on mains power, providing immediate energy reduction compared to the CFL equivalents it replaces. The 4000K colour temperature produces a neutral cool white light that suits office environments, retail spaces, workshops and commercial corridors where clear visibility is required without the warm cast of residential lighting. The elongated tubular profile distributes light evenly across the length of the lamp.

The LED technology increases operational life compared to CFL alternatives, reducing the frequency of replacements in fixtures mounted in ceiling voids or other access-restricted locations. The bulb carries an E energy rating under current UK regulations. Installation requires compatibility with 2G11 LED fixtures or retrofitted CFL fixtures with the ballast bypassed — verify fixture compatibility before ordering.

Frequently Asked

Is this bulb dimmable?

No. This Energizer LED PLL bulb is non-dimmable and must be used on standard mains switching only. Attempting to dim a non-dimmable LED can cause flickering, premature failure or damage to both the bulb and the dimmer circuit.

What does the 2G11 base fit?

The 2G11 is a 4-pin plug-in base used in PLL (parallel linear lamp) fixtures, commonly found in commercial ceiling panels, retail display lighting and under-cabinet fittings. The base has two pairs of pins spaced 95mm apart on centre. Check your existing fixture base before ordering.

Can this replace a CFL PLL bulb directly?

It depends on the fixture. LED PLL bulbs operate differently from CFL equivalents and may require the existing magnetic or electronic ballast to be bypassed. Some LED-compatible fixtures accept direct plug-in replacement. Verify fixture compatibility or consult an electrician before installation.

What colour temperature is 4000K?

4000K is a neutral cool white that sits between warm white (2700-3000K) and daylight white (5000-6500K). It provides clear, focused light without the yellow cast of warm white or the blue tint of daylight white, making it suitable for task lighting in commercial and industrial settings.
