Navi B DT10 MR16 Recessed Downlight - Black Matt

The Navi B DT10 is a round recessed downlight built around a single GX5.3 MR16 bulb rated to a maximum of 10W, running on 12V supply (12V AC or 12V DC). It sits flush in the ceiling for a clean, low-profile finish, with the light source you choose dictating the lumen output, beam spread and colour temperature. In US terms a fitting of this kind is a small recessed can light, taking a low-voltage MR16 reflector lamp rather than an integrated LED module, so the brightness and tone are set by the bulb you specify.

Because the output depends on the MR16 bulb fitted, this downlight suits accent and general task roles where you want pools of directional light rather than a fixed wall of brightness. It works well over kitchen worktops, in hallways and across living and dining spaces, and a row spaced evenly across a ceiling builds layered light that you can dim or scene if your bulb and supply allow. As an IP20 fitting it is for dry indoor rooms only, so keep it clear of bathrooms, porches and any outdoor or damp position.

The body is aluminium alloy in a black matt finish, with a compact Ø81mm face and a 21mm depth that drops into a matching cut-out in the ceiling void. At just 64g it is light to handle during installation, and the GX5.3 holder accepts standard MR16 lamps run from a 12V transformer. Confirm your transformer rating covers the lamps fitted, and note the bulb is specified separately. The Navi range offers further trims and finishes if you want to match fittings across adjoining rooms.

What size cut-out does this downlight need?

The fitting has an overall face diameter of Ø81mm and a recess depth of 21mm. The cut-out is the hole the body drops into in the ceiling, so it should be slightly smaller than the 81mm trim to let the face sit flush. Always check the supplied template before cutting.

Does it need a transformer?

Yes. This is a low-voltage downlight running on 12V AC or 12V DC, so it requires a suitable 12V transformer or driver between the mains and the fitting. Make sure the transformer's rating covers the total wattage of all the MR16 lamps on the circuit.

Is the MR16 bulb included, and can it be dimmed?

The fitting takes a GX5.3 MR16 lamp rated up to 10W, supplied separately so you can choose the lumen output and colour temperature. Dimming depends on the bulb and the transformer you pair it with, so check both are marked as dimmable if you want that control.

How do I clean the downlight?

Switch off and let any lamp cool first, then wipe the black matt aluminium trim with a soft dry or slightly damp cloth. Avoid solvents or abrasive cleaners, which can mark the finish. Take care not to disturb the lamp inside the GX5.3 holder.
