Deep inner channel
About 17.3 x 15.1mm of space lets the strip sit back from the diffuser, helping chips blend into a continuous line.
NLP-1722 · Aluminium Profile
A Line of Light With No Frame, No Dots
The NLP-1722 is a trimless plaster-in profile with a deep inner channel and a diffuser. The strip sits well back from the opening, so light blends into one clean, continuous line.
Why depth matters
Space Behind the Diffuser Is What Smooths the Line
Visible dotting is the most common complaint about recessed linear lighting. The fix is distance: when the strip sits further from the diffuser, light from neighbouring chips overlaps before it leaves the opening. The NLP-1722 is built around that principle, with an inner channel of about 17.3mm by 15.1mm inside a 57.3mm by 22.6mm body.
Because the flanges are covered by plaster, the finished ceiling or wall meets the glowing opening directly. The result reads as an architectural cut in the surface rather than a fitting added to it.
What comes in the pack
Each pack holds 40 profiles and 40 diffusers, so every length arrives with its matching diffuser. Available in black and white.
Install in the right order
Fix and plaster the profile first. Fit the strip and diffuser last, after painting, to keep the opening clean and the diffuser unmarked.
Features
Built Into the Architecture
Trimless plaster-in
Flanges lock into plaster or putty and disappear, leaving no visible frame at the opening.
Diffuser included
A matching diffuser comes with each profile for an even, soft-edged glow.
Rigid body
A substantial section of roughly 253g per metre that resists bowing over long runs.
Black or white
White vanishes into painted ceilings, black gives a graphic edge.
Project packs
Packs of 40 profiles and 40 diffusers keep quantities matched on large jobs.

FAQ
Questions Installers Ask
The aluminium flanges sit under plaster or putty, so the ceiling or wall finish runs straight into the light opening. Once painted, no metal frame is visible around the line.
Distance lets light from neighbouring chips overlap before it reaches the diffuser. The inner channel of about 17.3mm by 15.1mm lets the strip sit back, so the line reads as one continuous bar rather than a row of points.
Each pack holds 40 profiles and 40 diffusers, so every length has a matching diffuser. This suits project orders where quantities need to line up.
Black and white. White disappears into painted ceilings, while black gives a crisp graphic edge against darker finishes or feature walls.
Fix the profile at the planned level, check it for straightness, plaster over the flanges and sand flush, then paint. Fit the strip and diffuser only after finishing, and mask the open channel until then.
Yes. Butt the ends tightly, align the flanges and the channel, and keep the strip continuous across the joint. Cut ends square so the plaster line stays clean.
