Luto CTX Ø90 Round Recessed Downlight MR16 - White

The Luto CTX is a round recessed downlight that takes a single MR16 lamp on a GX5.3 base, giving you free choice over the bulb, its wattage up to 10W and its beam to suit the job. It runs on 12V supply, either AC or DC, so it pairs with a low-voltage transformer rather than connecting direct to mains. Sitting flush in the ceiling with a slim white bezel, it directs light downward in a neat round aperture, which makes it an easy way to build a recessed scheme in US terms this is the recessed can light format scaled down for a compact MR16 lamp.

Use it across hallways, kitchens, landings and living spaces where a low-profile ceiling point is wanted without a surface fitting breaking the line. Because the lamp is separate, the spread and brightness depend on the MR16 you choose, so a tighter beam picks out a worktop or feature while a wider one washes a general area. For broader rooms, plan several of these on a grid so the pools of light overlap evenly rather than leaving dark gaps between fittings. It is an indoor downlight only, so keep it clear of bathrooms, porches and any damp or outdoor position.

The body is aluminium alloy in a white finish, measuring 88mm in overall diameter and 22mm deep, and weighs just 72g. It carries an IP20 rating, which confirms it is for dry interior locations away from moisture. Installation is recessed into the ceiling, dropping into a cut-out behind the visible trim, and the GX5.3 holder accepts standard MR16 lamps on a 12V low-voltage circuit. Dimming and colour temperature follow whichever MR16 lamp is fitted, so the fixture stays flexible across different rooms. The Luto range includes matching fittings in other trim sizes if you want a consistent look throughout the home.

What size cut-out does it need?

The downlight has an overall trim diameter of 88mm, so allow a slightly smaller ceiling cut-out behind it for the body to recess into. Always check the recess depth against the 22mm fixture height plus space for the lamp and wiring above the ceiling line.

Does it need a transformer?

Yes. It runs on a 12V low-voltage supply, accepting either 12V AC or 12V DC, so it requires a suitable transformer or driver rather than connecting straight to mains. Match the transformer rating to the total wattage of the MR16 lamps on the circuit.

Can I dim it and change the colour temperature?

Both depend on the MR16 lamp you fit rather than the downlight itself, since the GX5.3 holder takes a separate bulb. Choose a dimmable MR16 in your preferred warm or cool tone, and pair it with a compatible low-voltage dimmer.

How do I clean the fitting?

Wipe the white trim with a soft, dry or lightly damp cloth once the lamp has cooled, avoiding solvents or abrasive cleaners that could mark the aluminium. Take care not to dislodge the recessed body when wiping around the bezel.
