Katro 225x225 18W Recessed Downlight IP44 Square Cool White - White

The Katro is a square recessed LED downlight that drops flush into the ceiling, drawing 18W from a 220-240V AC supply to deliver 1260 lumens. The light is fixed at 4000K cool white, a clean neutral tone that reads as crisp daylight without going blue, and a wide 110 degree beam spreads it evenly rather than throwing a tight pool. In North American terms a fitting like this fills the role of a recessed can light, though the Katro keeps a slim square trim instead of the usual round profile.

Its output makes it a good fit for everyday rooms where you want broad, comfortable coverage. One unit lights around 4 m² at general lighting levels, so a small bathroom, an ensuite, a hallway run or a utility space typically calls for a few spaced across the ceiling. The wide beam and 4000K tone suit task-adjacent areas such as basins, mirrors and worktops, where neutral light helps you see colours accurately. For ceilings of standard domestic height the spread holds up well; lower ceilings benefit from spacing the fittings a little wider so the pools of light overlap gently.

Built from aluminium alloy with a white finish, the Katro carries an IP44/20 rating, which makes it splash-resistant and suitable for bathroom zones and sheltered, covered spots such as a porch or carport. Keep it clear of fully-exposed positions, direct water jets and submersion. The fitting recesses into the ceiling and measures 225 x 225 x 20 mm with a slim 20 mm depth, weighing 470 grams. It is not dimmable, so pair it with a standard switch rather than a dimmer. The Katro range includes other wattages and tones if you need to match output across rooms.

Can the Katro be used in a bathroom?

Yes, its IP44 rating makes it splash-resistant and suitable for sheltered bathroom zones, such as ceilings away from direct spray. It also handles covered outdoor spots like a porch or carport. Avoid fully-exposed positions or anywhere it would meet direct water jets.

What size cut-out does it need?

The cut-out is the hole the fitting drops into, which is smaller than the 225 x 225 mm overall square trim that sits on the ceiling surface. Check the supplied installation diagram for the exact cut-out dimension before you cut, as the trim overlaps the edge to hide it. The slim 20 mm body needs only a shallow void above the ceiling.

Is the Katro dimmable?

No, this version is not dimmable, so it should be wired to a standard on/off switch rather than a dimmer circuit. Fitting it to a dimmer can cause flicker or buzzing. If you need adjustable brightness, look at a dimmable model in the range instead.

How do I clean it?

Wipe the white trim with a soft, dry or barely damp cloth, switching the power off first and letting the fitting cool. Avoid abrasive cleaners or solvents, which can mark the painted aluminium and the diffuser. A gentle dust now and then keeps the light output looking bright and even.
