Description

The Energizer 3W LED PLS/E bulb uses a 2G7 4-pin base and delivers 370 lumens at 4000K cool white, replacing traditional 7W CFL compact fluorescent lamps in downlights, bulkheads, and under-cabinet fittings. The twin-tube PLS form factor fits low-profile compact luminaires where space is limited, and the 2G7 base provides a secure four-pin connection that prevents the bulb from rotating once installed.

Designed for commercial and residential use in stairwells, corridors, storage rooms, and workshop areas where functional task lighting is needed, the bulb switches on instantly at full brightness with no warm-up delay. The 4000K colour temperature sits between warm white and daylight, producing a neutral cool white tone that reduces colour distortion and works well in utility spaces, offices, and areas where clear visibility matters more than ambience.

The LED technology draws 3W on mains power, consuming approximately 60% less energy than the 7W CFL it replaces, while the rated 30-year lifespan at typical usage reduces replacement frequency and maintenance costs in hard-to-reach fittings. The bulb is non-dimmable and carries an E energy rating under current EU regulations. The compact tubular form measures approximately 110mm in length including the base, fitting most standard PLS/E lamp holders without modification.

Frequently Asked

What does the 2G7 base fit?

The 2G7 is a 4-pin compact fluorescent base used in low-profile downlights, bulkheads, and under-cabinet fittings. The four pins lock the bulb into the lamp holder, preventing rotation. If your existing CFL has a 2G7 base, this LED bulb is a direct replacement.

Can this bulb be used with a dimmer switch?

No. This bulb is non-dimmable and will not function correctly with dimmer switches. Attempting to dim it may cause flickering or damage the bulb.

What is the difference between 4000K and 3000K?

4000K is a cool white that appears neutral to slightly blue-toned, producing clearer task light with less warmth. 3000K is a warm white that appears more yellow-orange, similar to traditional incandescent bulbs. 4000K suits work areas, corridors and storage; 3000K suits living spaces and bedrooms.

How long does the bulb last?

Energizer rates this bulb for a 30-year lifespan under typical residential use patterns (approximately 2-3 hours per day). In commercial settings with longer operating hours, the lifespan will be proportionally shorter but still significantly longer than CFL equivalents.
