Description

The Energizer 3.4W GU10 LED bulb is a direct replacement for 50W halogen spotlights, delivering 345 lumens at 3000K warm white colour temperature. The GU10 twist-and-lock base fits standard UK downlight fittings, recessed ceiling lights and track lighting without requiring new fixtures or adapters. The non-dimmable LED driver provides instant-on light at full brightness from switch-on.

Designed for kitchens, bathrooms, hallways and utility rooms where downlights run for extended periods, the 3.4W draw reduces energy consumption by 93% compared to the 50W halogen equivalent. The 25-year rated lifespan (based on 3 hours daily use) cuts bulb replacement frequency from annual halogen changes to once every quarter-century, reducing both maintenance effort and long-term bulb costs.

The 3000K colour temperature provides a warm white output that sits between the yellow-orange cast of traditional tungsten bulbs (2700K) and the cooler neutrality of office lighting (4000K+). This makes the bulb suitable for residential spaces where warmth is preferred but true colour rendering is also needed, such as bathroom mirrors, kitchen worktop task lighting and hallway downlight circuits. The 50mm diameter and 54mm height match standard GU10 halogen dimensions, so the bulb sits flush within recessed housings.

Frequently Asked

What wattage halogen does this replace?

This 3.4W LED bulb is rated as a 50W halogen equivalent based on lumen output. At 345 lumens it matches the light output of a standard 50W GU10 halogen while drawing 93% less power.

Is this bulb dimmable?

No. This bulb uses a non-dimmable LED driver and will not work with dimmer switches. Attempting to use it on a dimmed circuit may cause flickering or damage the bulb.

What colour is the light?

The bulb produces 3000K warm white light, which sits between the yellow-orange warmth of traditional tungsten bulbs (2700K) and the cooler, more clinical white of office lighting (4000K). It works well in residential bathrooms, kitchens and hallways where a warm but not overly yellow light is preferred.

Will it fit my existing GU10 downlight?

Yes. The 50mm diameter and 54mm height match standard GU10 halogen dimensions, so it fits all standard UK GU10 downlight fittings and recessed housings without modification.
