Collingwood 1901 Double Adjustable Trimless Downlight - All White (Fire-Rated)

One Fitting, Two Independent Beams

The Collingwood 1901 Double Adjustable Trimless Downlight combines two separate light engines into a single plaster in fitting, so you get twin beams from one 70 to 90mm cutout rather than two separate downlights punched into the ceiling. Each head carries its own 9.6W LED engine, for 19.2W combined, and tilts up to 20 degrees independently of the other, so the two beams can be aimed at different points in the room.

Finished All White

This version is finished all white, so once it is plastered in, the face plate and both heads read as one continuous surface rather than a contrasting trim. It is a quiet, unobtrusive option for a ceiling that already has plenty going on, letting the light do the work instead of the fitting.

How It Works

• Two 9.6W LED engines built into one fitting, 19.2W combined output
• Choice of 2700K extra warm white at around 600 lumens, 3000K warm white at around 625 to 650 lumens, or 4000K cool white at around 725 to 750 lumens
• A dim to warm option is also available, running from 3000K down to 1800K as it dims
• CRI90+ across every colour temperature, so colours read accurately under the light
• Beam angle of 12, 24 or 50 degrees depending on the variant chosen
• Each head tilts up to 20 degrees independently to aim the beam where it is needed
• Supplied with a driver wired in via cable, compatible with mains, 1 to 10V or DALI dimming depending on the variant selected

Where It Works Best

This downlight is rated IP20, so it belongs in dry indoor rooms only, not bathrooms or anywhere exposed to moisture. It suits living rooms, kitchens, dining rooms, hallways, offices, stairwells and commercial spaces. The twin head design earns its keep wherever you want two beams from a tight run of ceiling, over a stretch of kitchen units, either side of a hallway or landing, or lighting two separate spots in a room without adding extra cutouts.

Collingwood Lighting

Collingwood Lighting designs and manufactures its LED products from Sywell in Northamptonshire, and has focused on LED technology since 2002. The brand states it was among the first to bring fire rated LED downlights to the UK electrical wholesale market, which is worth knowing here since this fitting carries its own 30 minute fire rating. Collingwood has also been awarded a Gold medal by EcoVadis, placing it in the top 5 percent of companies assessed globally for sustainability.
