Collingwood 1901 Slim Fixed Round Downlight 75mm diameter - All White (Fire-Rated)

A neat, fixed downlight that sits flush and out of the way

The 1901 Slim Fixed Round Downlight is built for ceilings where you want light without any fuss. It is fixed rather than adjustable, so once it is in the ceiling it stays pointed straight down, giving a clean, low profile look with nothing to tilt or aim.

Finished in white, built from aluminium

This version comes in an all white finish with an aluminium body, so the bezel sits quietly against a white ceiling rather than standing out. The visible bezel measures 75mm across with a 65 to 68mm cut out, and once you allow for the spring clips it needs around 104mm of ceiling void and roughly 72mm of depth above the ceiling line, so it fits most standard downlight holes without any awkward resizing.

How It Works

• Runs at a total of 9.6W with fully integrated LEDs, so there is no separate bulb to buy or replace.
• Choose from 2700K, 3000K or 4000K fixed colour temperatures, or a dim to warm option that shifts from 3000K down to 1800K as it dims.
• Available with a 12°, 24°, 45° or 50° beam angle, so you can match the spread of light to the room.
• Dimmable via mains, 1 to 10V or DALI control, depending on which driver option you choose.
• Wired in parallel, with the driver supplied as part of the fitting.

Where It Works Best

Collingwood lists this downlight for living rooms, kitchens, dining rooms, hallways, offices, stairs and commercial spaces, with the IP65 version also rated for bathroom zone 1. It suits any ceiling where you want even, low profile downlighting rather than a statement fitting, whether that is a run above a kitchen worktop, a hallway, or a landing.

Collingwood Lighting

Collingwood Lighting designs and manufactures its LED products from Sywell in Northamptonshire, and has specialised in LED technology since 2002. The brand says it was among the first to bring fire rated LED downlights like this one to the UK electrical wholesale market, alongside waterproof and mains dimmable options. Collingwood has also been awarded a Gold medal by EcoVadis, placing it in the top 5% of companies assessed globally for sustainability.

Good to Know

• Comes with a 7 year warranty from Collingwood.
• This product is non returnable, so do check the spec carefully before ordering.
• Available in IP44 or IP65. The IP65 version is rated for bathroom zone 1 as well as every other room listed above. See our guide to bathroom lighting zones if you are not sure which zone your ceiling falls into.
• Fire rated, which matters if it is going into a timber or joisted ceiling.
• As this is a mains wired fitting, Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

Is this downlight adjustable?

No. It is a fixed downlight, so once it is fitted it points straight down and does not tilt like an adjustable gimbal version.

What size hole do I need to cut?

A cut out of 65 to 68mm, with a visible bezel diameter of 75mm once fitted.

Can I use it in a bathroom?

Yes, in its IP65 version it is rated for bathroom zone 1. The IP44 version is intended for living spaces, kitchens, dining rooms, hallways, offices and stairs rather than bathrooms.

What dimming options are available?

Mains dimming, 1 to 10V or DALI, depending on which driver variant you order.

Does it come with a driver?

Yes, the driver is supplied with the fitting and wires in via cable.

Is a bulb included?

It uses fully integrated LEDs rather than a separate replaceable bulb, so there is nothing extra to buy or fit.
