Collingwood 1901 Double Adjustable Trimless Downlight - White Housing/Black Baffle (Fire-Rated)

Two Heads, One Trimless Finish

This double head 1901 downlight is built to vanish into a ceiling. The trimless plaster in edge means there's no visible ring once it's skimmed and painted, just two clean circles of light. It's a good pick when you want twin spots from one fitting without two separate bezels breaking up a flat ceiling.

White Housing, Black Baffle

The housing is white and each of the two heads has a black baffle set into it, giving a small point of contrast against a pale ceiling once the light is on. The body is aluminium, and each head adjusts independently by 20 degrees, so you can angle the two beams differently even though they share one fitting.

How It Works

• Two 9.6W LED engines, 19.2W in total, run from a plug and play driver wired in parallel
• Each head needs a cutout of 70 to 90mm
• Choose a beam angle of 12, 24, 45 or 50 degrees
• Choose a colour temperature of 2700K, 3000K, 4000K, or a Dim to Warm option that runs from 3000K down to 1800K
• Dimming is available as mains, 1 to 10V or DALI, depending on the variant you order

Where It Works Best

With an IP20 rating, this is a fitting for dry indoor ceilings rather than anywhere wet or steamy. Think living rooms, kitchens, dining rooms, hallways, offices, stairwells and commercial spaces, anywhere a run of twin downlights makes sense, such as either side of a hallway or over a kitchen island.

About Collingwood Lighting

Collingwood Lighting designs and manufactures its LED products from Sywell in Northamptonshire, and this fire rated downlight sits at the centre of what the brand says it does best. Collingwood states it was among the first to bring fire rated LED products to the UK electrical wholesale market, alongside sealed for life and mains dimmable options, and the company has specialised in LED technology since 2002. It has also been awarded a Gold medal by EcoVadis, putting it in the top 5% of companies assessed globally for sustainability.

Questions People Ask

Can the two heads be aimed at different angles?
Yes. Each head adjusts by 20 degrees on its own, so the two beams don't have to point the same way.

What size hole do I need to cut for each head?
Each head needs a cutout of 70 to 90mm, which allows a little room for adjustment once it's fitted.

Is this suitable for a bathroom?
No. It's rated IP20, which means it's designed for dry indoor rooms rather than bathrooms or other high moisture areas.

What dimming options does it come with?
It's available in mains dimming, 1 to 10V or DALI, depending on which variant you choose, with the driver supplied and both heads wired in parallel.

Do I need an electrician to fit this?
Yes. It's a mains wired fitting, so Moonlight Design recommends having it installed by a registered NICEIC electrician.
