Collingwood 1901 Fixed Square Downlight - White Housing/Black Baffle (Fire-Rated)

A Downlight That Keeps a Ceiling Looking Calm and Considered

Recessed lighting works best when you forget it's there until you switch it on. This 1901 downlight from Collingwood is built for exactly that. It sits flush in the ceiling with a small square bezel and a black baffle set into the aperture, so the fitting reads as a clean shadow gap rather than a shiny disc staring back at you.

White Housing, Black Baffle, Fixed Square Bezel

This version pairs a white powder coated housing with a black baffle, giving a crisp contrast against a white ceiling while the recessed black baffle keeps the light source itself out of view. The bezel is square rather than round, which suits a modern, gridded ceiling layout, and it's a fixed head rather than a tilting one, so it points straight down and stays there. The ceiling cutout runs from 65 to 78mm, and the aluminium housing is compact enough to fit tight void spaces.

How It Works

• Runs at a total of 9.6W, with a choice of 2700K, 3000K or 4000K white, or a dim to warm option that shifts from 3000K down to 1800K as you dim it
• All colour temperatures are CRI90+, so colours read accurately under the light rather than looking flat
• Beam angle is selectable at 12°, 24°, 45° or 50°, from a tight spotlight to a wider wash
• Dimming is available via mains, 1 to 10V or DALI control, and the driver is supplied with the fitting and wired in via cable rather than needing to be bought separately
• The fitting is wired in parallel, which makes it straightforward to run several downlights from the same circuit

Where It Works Best

Because it's fixed rather than adjustable, this downlight suits spaces where you want even, symmetrical light rather than aimed accents, think a run of downlights along a hallway or stairwell, a grid across a kitchen ceiling, or spaced evenly through a living room or office. It's rated for living rooms, kitchens, dining rooms, hallways, offices and stairwells across both IP versions, and commercial settings too. Choose the IP65 option and it also covers bathroom zone 1, so the same downlight can carry through from a hallway into an ensuite without switching styles.

About Collingwood Lighting

Collingwood Lighting designs and manufactures its LED products from Sywell in Northamptonshire, and has focused on LED technology since 2002. On a fire rated fitting like this one, that history matters: Collingwood says it was among the first to bring fire rated LED downlights, alongside fully waterproof, sealed for life fittings and mains dimmable products, into the UK electrical wholesale market. The brand has also been awarded an EcoVadis Gold medal, placing it in the top 5% of companies assessed globally for sustainability.

Questions People Ask

What's the difference between the IP44 and IP65 versions?
The IP65 version is sealed against dust and water splashes and is rated for bathroom zone 1, while the IP44 version suits everyday dry rooms like living rooms, kitchens, hallways and offices.

Can I angle the beam once it's fitted?
No. This is a fixed head downlight, so it points straight down and can't be tilted. If you want to redirect the beam, you'd need an adjustable fitting instead.

What ceiling cutout size do I need?
The housing fits a cutout of 65 to 78mm, so it's worth measuring your existing hole or planned cutout against that range before ordering.

Is the dimmer switch included?
No. The fitting includes a driver set up for mains, 1 to 10V or DALI dimming depending on which option you choose, but you'll still need a compatible dimmer switch or control system to actually dim it.

Can several of these go on one circuit?
Yes. The fitting is wired in parallel, which is what allows multiple downlights to be run from the same circuit.
