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

A Ceiling Light That Barely Shows It's There

The 1901 Single Fixed Trimless Downlight sits flush in the ceiling with no visible trim ring, so all you see from below is a clean circle of light. It's part of Collingwood's wider 1901 range, which is built around the same low glare, high comfort approach across every finish.

White Housing, Black Baffle

This version pairs a white aluminium housing with a black baffle recessed inside the aperture. The white body blends into a white ceiling, while the black baffle inside cuts glare and hides the light source from view, so you get a soft wash of light rather than a visible bulb when you look up at it. It's a fixed downlight, so the beam points straight down rather than tilting to pick out a wall or feature.

How It Works

• Single 9.6W LED module built into the fitting, so there's no separate bulb to buy or replace
• Choice of colour temperature: 2700K, 3000K, 4000K, or a dim to warm option that shifts from 3000K down to 1800K as you dim it
• Beam angle choice of 12°, 24°, 45° or 50°, so you can pick a tight spot or a broader spread depending on where it's going
• CRI of 90+ so colours read true under the light
• Dimmable via mains, 1 to 10V or DALI, with the driver sold separately and matched to your chosen method
• Fitted with rolled spring clips and plug and play connectors, so first and second fix wiring is straightforward

Where It Works Best

Collingwood rates this fitting at IP44 or IP65 depending on which version you choose, and it's fire rated for 30 minutes in solid timber, I-joist and metal web ceiling joists. That combination makes it a genuine option for kitchens, bathrooms, hallways, stairs and living spaces, as well as commercial ceilings where fire rating matters. The wider 50° beam option works well in corridors and open plan areas where you want an even spread rather than a tight pool of light. If you're lighting a bathroom, check the IP rated version matches the zone you're installing into: read our guide to bathroom lighting zones.

Made By Collingwood Lighting

Collingwood 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 fully waterproof, sealed for life and mains dimmable products. Collingwood has also been awarded a Gold medal by EcoVadis, placing it in the top 5% of companies assessed globally for sustainability.

Questions People Ask

What does trimless mean here?
There's no visible trim ring around the aperture. The white housing sits flush with the ceiling line, so from below you just see the black baffle and the light itself.

Why pick the black baffle over a white one?
The black baffle sits recessed inside the white housing and absorbs stray light, which cuts glare and makes the light source harder to see when you look up at an angle. It reads as a neat dark circle rather than a bright ring.

What does the fire rating actually protect against?
It means the fitting has been tested to maintain fire resistance for 30 minutes when installed into solid timber, I-joist or metal web ceiling joists, so cutting a hole for the downlight doesn't compromise the ceiling's fire separation.

How does the dim to warm option work?
Instead of a single fixed colour temperature, this option shifts the white light from a cooler 3000K down to a warm 1800K as you dim it, similar to how halogen and incandescent bulbs used to behave.

Which beam angle should I choose?
12° gives a tight, focused spot for highlighting one area, 24° or 45° suit general downlighting in most rooms, and 50° spreads the light wider, which works well in hallways, corridors or larger open areas.
