18W IP54 CCT Adjustable Surface Mounted Downlight - White

This is a surface mounted LED downlight measuring 300mm across and just 58mm deep, so it fixes straight onto the ceiling with no cut-out and no void needed above it. The LED board is built in, so there is no separate lamp to buy now or replace later. It draws 18W and returns 1,790 lumens, and the colour temperature is adjustable rather than fixed, so one fitting can give a warmer or a cooler white depending on the room it ends up in. It carries an IP54 rating, which covers it against dust and splashing water from any direction.

Because nothing needs recessing, it suits ceilings you cannot cut into: concrete, or plasterboard with pipework and joists sitting close above. IP54 means it is rated for bathroom zones 2 and 3, so it can go over a basin or across the main floor area of a bathroom, rather than directly above a bath or inside a shower enclosure. Elsewhere it works as the single central light in a hallway, a landing, a cloakroom, a utility room or a small kitchen, where the 120 degree spread puts light across the whole floor instead of pooling it in one place.

It is dimmable, so pair it with a trailing edge LED dimmer and check the dimmer's minimum load, since a single 18W fitting can sit below what some older dimmers need to run smoothly. The colour temperature is adjustable, though the individual kelvin values are not stated by the manufacturer, so it is worth setting the white you want at first fix and matching anything else in the same room to it. Rated life is 50,000 hours. You receive one fitting, with a minimum order of one. It sits alongside our other round downlights, including recessed panel versions at 12W, 18W and 24W, a quick connect GU10 downlight and an emergency downlight.

Do I need to cut a hole in the ceiling for this?

No. It is surface mounted rather than recessed, so it fixes onto the ceiling and projects 58mm below it, with no cut-out to make.

Can I put it in a bathroom?

Yes. The IP54 rating covers bathroom zones 2 and 3, so over a basin or across the general floor area, but not inside a shower or directly over a bath. Bathroom wiring should be carried out by a qualified electrician.

Will it dim, and what dimmer should I use?

The specification states that it is dimmable. A trailing edge LED dimmer is the usual choice, and it is worth checking the dimmer's minimum load, as a single 18W fitting is a light electrical load.

Which colour temperatures can I choose from?

The colour temperature is adjustable rather than fixed. The manufacturer does not state the individual kelvin settings, so set it on site and match it to the other lights in that room.

What old fashioned bulb wattage does 18W replace?

No equivalent wattage is stated by the manufacturer, so compare on brightness instead: this fitting is rated at 1,790 lumens, which is the figure to check against whatever it replaces.

How much of a room will one cover?

It measures 300mm across and spreads light over 120 degrees at 1,790 lumens, which suits a hallway, landing, cloakroom or small room as a single central light.
