Rounda 12W Ø170 Recessed Downlight IP44 Cool White - White

The Rounda is a round recessed LED downlight that drops flush into the ceiling for a clean, low-profile finish. It draws 12W and delivers 780 lumens at a fixed 4000K cool white, a crisp neutral tone that keeps detail sharp without going clinical. The wide 110 degree beam spreads light broadly rather than spotting a single point, so the fitting washes a soft, even pool across the area below. North American buyers will recognise this recessed format as a can light, here in a slimline integrated LED build only 20mm deep, with a colour rendering of Ra 80 for natural-looking colours.

Measuring Ø169mm across, the Rounda gives around 3 m² of coverage at general lighting levels, which makes a run of them straightforward to plan across a bathroom, hallway, landing or kitchen ceiling. Spacing several units evenly avoids dark patches and the broad beam handles standard ceiling heights comfortably. The 4000K cool white tone suits practical rooms where clarity matters, such as a bathroom mirror zone or a busy hallway, and the modest 12W draw keeps a multi-light layout efficient at 65 lm/W.

Built from aluminium alloy with a white finish, the Rounda carries an IP44/20 rating, so it is splash-resistant and rated for sheltered, damp settings such as bathroom ceilings and covered porches. Keep it clear of direct water jets and fully exposed positions. The fitting is recessed into the ceiling cut-out and runs on 220-240V AC mains. It is not dimmable and uses an integrated LED rated for 15,000 hours, so there is no bulb to change. Other wattages and sizes sit alongside this model in the Rounda range from Kanlux.

What cut-out hole does the Rounda need?

The Rounda has an overall trim diameter of Ø169mm, and the cut-out is the smaller recessed hole the body drops into, so check the supplied installation diagram for the exact aperture rather than cutting to the trim size. The fitting is only 20mm deep, which suits ceilings with limited void space above. Recess it into a solid or plasterboard ceiling and connect to the 220-240V AC mains supply.

Can it be used in a bathroom?

Yes. The Rounda carries an IP44 rating, which makes it splash-resistant and suitable for sheltered bathroom ceiling zones away from direct spray. Keep it clear of areas exposed to direct water jets or standing water, and follow the relevant bathroom zone regulations for your installation.

Is the Rounda dimmable?

No, this model is not dimmable and should be run on a standard non-dimming circuit. Pairing it with a dimmer switch can cause flicker or shorten the life of the integrated LED. If you need adjustable output, plan the layout in separately switched groups instead.

How many lumens does it give and what room size does it cover?

Each Rounda delivers 780 lumens at 4000K cool white, covering around 3 m² at general lighting levels. For an even wash across a larger room, plan several units spaced evenly across the ceiling rather than relying on a single fitting. The wide 110 degree beam helps avoid dark gaps between lights.
