Morta B Round MR16 Downlight - Black

The Morta B is a recessed LED downlight built around a round glass body that drops neatly into the ceiling. It takes a single 12V MR16 lamp through its Gx5.3 holder, drawing up to 10W, so the output and beam angle follow whichever MR16 you fit. In US terms a fitting like this is the recessed can light or trim that holds a low-voltage MR16 reflector lamp, with the light source kept separate from the housing for easy swaps. The compact Ø90mm face sits flush once installed, giving a tidy point of light rather than a broad wash.

Used as part of a wider scheme, the Morta B suits hallways, landings, kitchens and living spaces where a run of recessed points gives even general lighting. Because the lamp is a directional MR16 reflector, it works well for marking a route, lifting a worktop or picking out a feature, and the number you space across a room sets the overall brightness. With a 12V supply it is an indoor fitting only, so plan it for dry rooms within the home and keep it clear of bathrooms, porches and any damp or outdoor location. Standard ceiling voids easily take the 36mm depth behind the trim.

Construction is glass with a black finish, giving a crisp recessed face that reads cleanly against a painted or plastered ceiling. The fitting is rated IP20 for dry indoor use and weighs 210g, dropping into a round ceiling cut-out and held by its mounting clips. It runs on 12V AC or DC, so it needs a suitable low-voltage transformer or driver sized to the total MR16 load on the circuit. The MR16 lamp itself is specified separately, letting you choose the wattage, beam and colour temperature to suit the room. Other finishes and shapes sit alongside it in the Morta range.

What size is the ceiling cut-out?

The Morta B has an overall face diameter of Ø90mm and sits 36mm deep behind the trim. Cut the ceiling hole to the manufacturer's recommended cut-out for the housing so the body drops through and the trim sits flush; the cut-out is smaller than the visible face.

Does it need a transformer?

Yes. The fitting runs on 12V AC or DC rather than mains, so it needs a low-voltage transformer or driver. Size the transformer to the combined wattage of all the MR16 lamps on that circuit, allowing for the 10W maximum per fitting.

Is the lamp included and can it be dimmed?

The Morta B uses a Gx5.3 MR16 lamp, which is specified separately so you can pick the wattage, beam angle and colour temperature you need. Dimming depends on the MR16 lamp and the transformer you pair with it, so check both are rated as dimmable before installing on a dimmer.

How do I clean the downlight?

Switch off and let the lamp cool, then wipe the glass face and black trim with a soft dry or slightly damp cloth. Avoid solvents and abrasive cleaners so the finish stays crisp, and do not let moisture reach the lamp holder or wiring.
