Energizer 7W Dimmable LED GLS Filament Bulb E27 2700K - Warm White

The Energizer 7W LED GLS is a dimmable filament bulb with an E27 screw base, delivering 806 lumens at 2700K warm white. The exposed filament design inside a clear glass envelope mimics the look of a traditional incandescent bulb while providing LED efficiency and a 15-year rated lifespan. At 7W it replaces a 60W incandescent, reducing energy consumption by approximately 88%.

Designed for table lamps, pendant fittings, bare-bulb fixtures and vintage-style lighting where the bulb itself is visible, the filament gives a decorative appearance whether the bulb is on or off. The 320-degree beam angle provides omnidirectional light distribution similar to a traditional GLS bulb, making it suitable for general room lighting as well as accent use. Dimmer compatibility allows output to be adjusted from full 806 lumens down to a low ambient level depending on the time of day or activity.

The GLS (General Lamp Service) shape is the standard pear-shaped bulb profile familiar from traditional incandescent lighting, measuring 60mm diameter and 109mm height. The E27 base fits standard UK lamp holders and ceiling pendants without requiring adaptors. The clear glass and visible filament suit industrial, mid-century and contemporary interiors where exposed bulbs are part of the aesthetic rather than hidden inside a shade.

Energy rating E under current UK labelling reflects the efficiency relative to other LED bulbs on the market. The 2700K colour temperature produces a warm, slightly amber-toned white light similar to traditional incandescent bulbs, making it appropriate for living rooms, bedrooms and dining areas where a cooler daylight tone would feel too clinical.

Is this bulb compatible with all dimmer switches?

The bulb is rated as dimmable, but compatibility depends on the specific dimmer model. Older rotary dimmers designed for incandescent bulbs may cause flickering or limited dimming range. For best results, use a trailing-edge or LED-compatible dimmer. If you experience issues, contact us with your dimmer model for compatibility advice.

What does 2700K warm white look like?

2700K produces a warm, slightly amber-toned white light similar to traditional incandescent bulbs. It's warmer than daylight (5000K-6500K) and creates a relaxed, cosy atmosphere suitable for living rooms, bedrooms and dining areas. Under this light, warm colours (reds, oranges, browns) appear richer while cooler colours (blues, greens) appear slightly muted.

How long does the bulb last?

Energizer rates this bulb for a 15-year lifespan based on average domestic use of approximately 3 hours per day. Actual lifespan varies with usage patterns, dimming frequency and ambient temperature. Running the bulb at lower dimmed levels typically extends its operational life.

Can I use this in a fully enclosed fixture?

LED bulbs generate less heat than incandescent bulbs, but they still need some air circulation for the internal electronics to remain within operating temperature. This bulb is suitable for most table lamps and open or semi-enclosed pendants. For fully enclosed outdoor fixtures or airtight housings, check that the fixture allows minimal ventilation or consider a bulb specifically rated for enclosed use.
