Energizer 7.2W E27 LED GLS Filament Bulb - Daylight 6500K Non-Dimmable

The Energizer 7.2W E27 LED GLS filament bulb delivers 1521 lumens at 6500K, producing a bright daylight white output that replicates natural midday light. The visible LED filament sits inside a clear glass GLS (General Lamp Service) envelope measuring 60mm diameter by 128mm height, giving the bulb the traditional appearance of a tungsten filament lamp while running on solid-state LED technology. The E27 Edison screw base fits standard UK and European lamp holders.

Designed for task lighting in kitchens, home offices, workshops and garages where colour accuracy and high visibility matter, the 6500K colour temperature renders colours more neutrally than warm white equivalents and reduces eye strain during close work. The 1521-lumen output matches a traditional 100W incandescent bulb while drawing only 7.2W, cutting running costs by approximately 93%. The bulb is non-dimmable and performs best on standard on/off switching.

The A energy rating reflects the conversion efficiency of mains electricity to visible light, with minimal waste heat compared to halogen or incandescent alternatives. The clear glass envelope allows the LED filament to be visible when lit, adding a decorative element to exposed-bulb fixtures in industrial, retro and minimalist interiors. Energizer rates the bulb for a 50-year lifespan under typical domestic use patterns (approximately 15,000-20,000 hours), significantly reducing replacement frequency compared to traditional bulbs.

Is this bulb dimmable?

No. This Energizer LED is non-dimmable and should only be used with standard on/off switches. Attempting to use it with a dimmer switch may cause flickering, buzzing or premature failure.

What's the difference between 6500K and 3000K bulbs?

6500K is daylight white, producing a bright, cool-toned light similar to natural midday light that enhances colour accuracy and visibility for task work. 3000K is warm white, producing a softer, yellow-toned light similar to traditional incandescent bulbs that creates a more relaxed atmosphere. Most users choose 6500K for kitchens, offices and workshops, and 3000K for living rooms and bedrooms.

What does the 50-year lifespan claim mean?

Energizer rates this bulb for approximately 15,000-20,000 hours of operation. At typical domestic use of around 3 hours per day, that translates to roughly 15-18 years of actual service. The 50-year figure assumes lower daily usage or accounts for the bulb's shelf life when not in constant use.

Can it replace a 100W incandescent bulb?

Yes. The 1521-lumen output closely matches a traditional 100W incandescent bulb, while this LED draws only 7.2W from the mains. The light quality differs due to the 6500K colour temperature being cooler than most incandescent bulbs, which typically run around 2700K.
