Frequently asked questions

What dimmer switch works best with this bulb?

For smooth, flicker-free dimming, use an LED-compatible trailing-edge dimmer switch rather than an older leading-edge dimmer designed for halogen bulbs.

How warm is 3000K compared to a standard halogen bulb?

3000K gives a similar warm, yellow-toned white to traditional halogen and incandescent lighting, so it's a comfortable, familiar match when upgrading older GU10 downlights.

Can I dim this bulb down very low without flickering?

When paired with a compatible LED dimmer switch, it should dim smoothly through its range; flickering at low levels is usually a sign the dimmer itself isn't LED-compatible.

Is the full glass body more likely to break than plastic GU10 bulbs?

The full glass construction gives a premium look and is built for normal household use, though as with any glass fitting it should be installed carefully.
