Dalla DTO-B (B) Round GU10 MR16 Recessed Spotlight Ø80 - Black

The Dalla DTO-B (B) is a round recessed spotlight that takes a single MR16 or PAR16 lamp on a Gx5.3 or GU10 base, drawing up to 10W. It runs on either 12V AC/DC or mains 220-240V AC, so it pairs with a low-voltage transformer or wires direct depending on the lamp fitted. Known to many buyers simply as an led spotlight, the term used in the United States too, it sits flush in the ceiling and directs a focused pool of light wherever it is aimed. The actual spread depends on the MR16 or PAR16 lamp you choose, which lets you tune the beam to the job.

This fitting suits accent and task work rather than washing a whole room, so think picture and shelf highlighting, marking out a kitchen worktop, or adding pinpoints over a reading chair. Because it is recessed, it keeps ceilings clean and is well suited to rooms where a flush finish matters, including lower ceilings where a surface fitting would intrude. Coverage is best judged by the lamp's beam: a narrow lamp throws a tight spotlight onto a single object, while a wider one lifts a small zone. Group several across a ceiling to build even accent lighting along a run of cabinets or artwork.

The body is aluminium alloy in a black finish, a compact Ø82mm round trim that projects 21mm and weighs just 58g. It carries an IP20 rating, which means dry indoor rooms only, so keep it clear of bathrooms, porches and anywhere exposed to damp. The lamp is supplied separately, letting you set wattage, beam angle and colour temperature to suit. The Dalla DTO-B (B) is part of a wider Dalla range of recessed spotlights, so matching trims and sizes are available to keep a scheme consistent.

Can this spotlight be used in a bathroom or outdoors?

No. The Dalla DTO-B (B) is rated IP20, which covers dry indoor rooms only. It should not be installed in bathrooms, near showers, in porches or anywhere exposed to moisture or the weather.

Is a bulb included, and is it dimmable?

The lamp is supplied separately, as the fitting accepts either a Gx5.3 (MR16) or GU10 (PAR16) lamp at up to 10W. Whether it dims depends on the lamp and, for the 12V option, the transformer you choose, so select a dimmable lamp and compatible control gear if you need dimming.

What beam angle does it give?

The beam is set by the lamp rather than the fixture, since the Dalla DTO-B (B) takes interchangeable MR16 or PAR16 lamps. A narrow lamp produces a tight accent spot, while a wider one covers more of a surface, so pick the beam to match the task.

How do I clean and maintain it?

Wipe the black aluminium trim with a soft, dry or barely damp cloth once the fitting is switched off and cool. Avoid solvents and abrasive cleaners so the black finish stays even, and check the lamp seats correctly when you wipe around it.
