Katro 300x300 24W Recessed Downlight Square Cool White - White

The Katro is a square recessed LED downlight drawing 24W and delivering 1680 lumens at a 4000K cool white tone, with a wide 110 degree beam angle that spreads light evenly rather than throwing a tight pool. In the US this kind of fitting is the recessed can light, and the Katro sits flush into the ceiling for that same clean, built-in look. Running from 220-240V AC mains and rated at Ra 80 for colour rendering, it gives a neutral, daylight-leaning light that keeps surfaces and finishes looking true.

Across the 300 by 300 mm face this single downlight covers around 6 m² at general lighting levels, which makes it a practical choice for a bathroom, an ensuite, a utility room or a covered porch where a sheltered position keeps it within its rating. For larger rooms, plan several units in a grid and space them by ceiling height so the 110 degree spread overlaps without leaving dark gaps. The cool white output suits task-heavy spaces such as a shower zone or a laundry area where clarity matters more than a warm tone.

Built from aluminium alloy with a white finish, the Katro carries an IP44/20 rating, so it is splash-resistant and happy in bathroom zones and covered outdoor spots like a porch or carport, though it should be kept clear of direct water jets and fully exposed positions. It recesses into the ceiling and is not dimmable, running at a fixed output across its rated 15,000 hour lifespan. At 760 g and only 20 mm deep it sits neatly into shallow voids. Niori stocks the wider Katro range in further wattages and tones.

What size cut-out does the Katro need?

Plan the ceiling cut-out to suit the 300 by 300 mm square body, checking the supplied installation diagram for the exact aperture before you cut. The fitting is only 20 mm deep, so it drops into shallow ceiling voids that deeper downlights would not fit. Always confirm the cut-out against the spec sheet rather than the outer trim dimension, as the two differ.

Can the Katro be used in a bathroom?

Yes, its IP44/20 rating makes it splash-resistant and suitable for bathroom zones and covered, sheltered outdoor spots such as a porch or carport. Keep it clear of direct water jets and avoid fully exposed positions, as the rating does not cover those. For a shower or wet area, follow the relevant zone requirements for your bathroom.

Is the Katro dimmable?

No, this downlight runs at a fixed output and is not dimmable, so it is not designed for use on a dimmer switch. It gives a steady 1680 lumens at 4000K cool white whenever it is switched on. If dimming is essential, choose a fitting that lists dimmable support.

How do I clean the Katro?

Wipe the white aluminium face and diffuser with a soft, dry or barely damp cloth once the fitting has been switched off and has cooled. Avoid abrasive pads and solvent cleaners, which can mark the finish over time. A gentle wipe is usually enough to keep the light output clear in a bathroom or utility setting.
