CARSA 18W LED Downlight Round - White

The Carsa is a round recessed downlight rated at 18W, drawing 220-240V mains and giving out 1260 lumens at an efficiency of 70 lm/W. Its colour temperature sits at a neutral 4000K, a clean white that suits general living and working spaces, and the wide 110 degree beam angle spreads light evenly rather than focusing it on a single spot. Buyers in the US will know this format as a recessed can light, dropped into a ceiling cut-out so the trim sits flush with the surface. The fitting measures Ø215mm with a low 35mm depth, keeping it neat against the ceiling line.

At 1260 lumens the Carsa covers around 4 m² at general lighting levels, so a run of several fittings is the usual way to light a kitchen, hallway or open living area to a comfortable brightness. The neutral 4000K tone reads as crisp daylight-white, which works well in task-leaning rooms such as kitchens and home offices where a warmer tone can feel too dim. As an IP20 fitting it is for dry indoor ceilings only, and should be kept clear of bathrooms, porches and any damp or exposed location. Standard ceiling heights suit it well given the broad beam.

Construction is aluminium alloy with a white finish, which helps draw heat away from the integrated LED and supports the rated 15,000 hour lifespan. The round body recesses into a ceiling cut-out and is held in place by sprung clips, with the wide 110 degree spread coming from the recessed format itself. This is a non-dimmable fitting, so it pairs with a standard on/off switch rather than a dimmer circuit. The white trim keeps the fitting discreet against painted plasterboard. The wider Carsa range covers further wattages for matching a scheme across rooms.

What size cut-out does the Carsa need?

The fitting has an overall trim diameter of Ø215mm, and it recesses into a ceiling cut-out slightly smaller than this so the trim sits flush against the surface. Always check the spec sheet for the exact cut-out figure before drilling, as the cut-out is distinct from the visible trim diameter. The shallow 35mm depth means it suits ceilings with limited void space above.

Is the Carsa dimmable?

No, this version is non-dimmable and is designed to run from a standard on/off switch. Wiring it to a dimmer circuit can cause flicker or shorten the life of the fitting. If you need dimming, choose a downlight specified as dimmable instead.

How many do I need for a room?

Each fitting delivers 1260 lumens and covers around 4 m² at general lighting levels, so a typical kitchen or living area will need several spaced evenly across the ceiling. As a rough guide, plan one fitting for every 4 m² of floor area and adjust for the room's use. Spacing them in a regular grid avoids dark patches between fittings.

How do I clean the Carsa?

Switch off the supply and let the fitting cool, then wipe the white trim and the lit face with a soft dry or slightly damp cloth. Avoid abrasive cleaners or solvents, which can mark the finish. As an IP20 fitting it must be kept dry, so never use a wet cloth that could let moisture into the housing.
