Description

The Lumos is a GU10 bulb adapter in matt black metal that converts a standard E27 or bayonet ceiling rose to accept GU10 twist-lock spotlight bulbs. The 57mm diameter housing contains the GU10 socket mechanism and provides a recessed aperture that directs light downward once a bulb is fitted.

Designed for downlight retrofits and custom pendant builds, the Lumos allows GU10 bulbs (sold separately) to be used in fittings that were not originally designed for them. The adapter screws or clips into a standard UK ceiling rose, then accepts any GU10 bulb via the twist-and-lock mechanism. This makes it useful for converting existing pendant fittings to directional spotlights, or for builders creating custom downlight positions without cutting into ceilings.

The matt black finish on the metal housing means the adapter blends into dark ceiling recesses or sits flush against black ceiling roses without visual contrast. The internal contact points provide stable electrical connection to the GU10 pins, and the metal construction dissipates heat from LED, halogen or other GU10 bulb types. The 57mm outer diameter matches standard downlight apertures used in UK residential and commercial installations.

Frequently Asked

What fitting does the Lumos convert from?

The adapter is designed to fit into standard ceiling roses or pendant lamp holders, allowing them to accept GU10 bulbs instead of E27 or bayonet bulbs. Check the specific fitting type on your ceiling rose to confirm compatibility before ordering.

Does it come with a GU10 bulb?

No. The Lumos is an adapter only. GU10 bulbs are sold separately and can be selected based on the brightness, colour temperature and beam angle required for your application.

What is the maximum wattage?

The adapter supports standard GU10 bulb wattages. Most GU10 LED bulbs are 3-7W; halogen GU10 bulbs are typically 35-50W. Check the specification of your existing ceiling rose or lamp holder for its maximum rated wattage before fitting.

Can it be used in recessed ceiling positions?

Yes. The 57mm diameter matches standard UK downlight apertures, making it suitable for custom downlight installations where a GU10 socket is needed but a full recessed fitting is not practical.
