Frequently asked questions

What dimmer switch should I use with this bulb?

For the smoothest, flicker-free dimming, pair it with an LED-compatible trailing-edge dimmer switch rather than an older leading-edge dimmer designed for halogen bulbs.

What does Energy Rating E mean?

Energy Rating E is part of the EU/UK lighting energy label scale, giving an indication of how efficiently the bulb converts electricity into light compared with other lamps on the scale.

Is 6500K daylight suitable for a dimmable bulb in a bedroom?

6500K is a bright, cool white, so many people prefer a 3000K warm white dimmable GU10 for bedrooms. This daylight version suits task-focused rooms like kitchens or offices better.

Why might the lumen figure vary slightly between listings for this bulb?

Lumen output can be rounded differently across retailers and packaging batches; this listing uses the manufacturer-confirmed figure of 345 lumens for the 3.6W version.
