Compact triangular body
At roughly 45 mm a side it sits in the corner as a slim line, not a heavy bulkhead.

A Ceiling Edge That Glows Without the Plaster
A compact triangular aluminium profile that sits in the wall-ceiling corner and sends hidden, diagonal light across both surfaces.
The idea
Cove lighting you can fit in an afternoon
A plastered cove needs planning, masons and a finished ceiling edge. The NLP-4545 gives the same soft, glare-free line from a surface-mounted profile that simply fits the right angle where wall meets ceiling.
Because the face is angled, light travels across the ceiling and down the wall in one sweep. The ceiling seems to float, the room feels taller and the corner looks finished instead of merely lit.
Light that hides its source. Downlights put the fitting in your eyeline. A corner cove keeps it out of sight and lets surfaces do the lighting, so you get soft, shadow-free ambience from a slim architectural line.
Retrofit friendly. No ceiling cutouts and no plasterwork means the profile suits occupied homes, rented spaces and tight project schedules.

Why designers specify it
Diagonal emission
The angled face throws light across ceiling and wall together, so the junction reads as one continuous glow.
Hidden light source
The strip sits behind a white PC diffuser. The room sees a clean line of light, never the chips.
Diffuser included
The cover clips on after the strip is placed, giving an even, dot-free finish.
No plasterwork
Fixes straight into the corner with screws or clips, so it suits renovations as well as new builds.
White or black powder coat
Match the wall so the profile disappears, or choose black for a crisp graphic edge.
Works with common strips
Single white, tunable white and colour-changing strips can sit in the channel.
Cut and join on site
Cut to length and butt or mitre at corners to carry the line around a whole room.
Prepare the surface first
Cove light grazes the ceiling and exposes every flaw. Smooth and paint the surface, keep the corner straight and choose a matte, light finish for the most even glow along the line.

FAQ
Installation questions, answered
A soft diagonal wash of indirect light across the ceiling and the adjacent wall. The strip is hidden behind the diffuser, so the room shows only a glowing line at the corner.
Fix the profile into the 90° corner where wall meets ceiling, one face on each surface, using screws or mounting clips. Place the LED strip in the channel, then clip on the diffuser. No ceiling cutout or plastering is needed.
A shadow gap is built into plaster as a recessed line. The NLP-4545 is surface mounted in the corner and reads as a slim profile, so it is quicker to install and easier to retrofit.
Standard strips of suitable width, including single-colour white, tunable white and colour-changing types. Check strip width against the channel before ordering. Warm white is the usual choice for cove effects.
Yes. Light washing upward gives an impression of extra height and the compact body adds little visual bulk. Keep strip output moderate so the ceiling does not look overlit.
White blends into most walls and ceilings and keeps attention on the glow. Black gives a defined architectural edge against dark walls or in contemporary interiors.
Yes. Cut the profile to length and join it along the run. Plan the strip layout and power feed in advance so the glow stays continuous.
Very. Cove light shows every flaw on the surface it grazes. Smooth and paint the ceiling and keep the corner straight; a matte, light finish gives the most even glow.
