What the NLP-4545 Does
The NLP-4545 is a compact triangular aluminium profile designed to sit in the right-angle junction where a wall meets the ceiling. Its angled diffuser face points diagonally outward — directing a continuous wash of soft indirect light across both surfaces at once. The LED strip sits inside the body, hidden from view. All the room sees is a clean, glowing line running along the ceiling edge.
No ceiling cutout. No plasterwork. The profile surface-mounts directly into the corner with screws or mounting clips, and the PC diffuser cover clips on afterward. The result is cove lighting that is both elegant and straightforward to install — a premium architectural effect with minimal site disruption.

One Profile. Light Spreading Both Ways.
The NLP-4545's triangular body sits at 45° in the corner. Its open face angles the light out diagonally — washing the ceiling overhead and grazing the wall surface below in a single, unified glow. From anywhere in the room, the LED itself is invisible behind the diffuser. Only the light remains.
The Lighting Effect
Diagonal Cove Wash
Light fans outward from the corner at 45°, sweeping softly across the ceiling and the top portion of the wall in one continuous movement.
Zero Glare, Fully Indirect
The LED source is sealed inside the profile body. The PC diffuser further softens any point brightness. No hot spots, no glare — just even, diffused light.
Floating Ceiling Effect
By washing the ceiling from its perimeter inward, the light separates the ceiling plane visually — creating the illusion that it hovers above the walls.
Greater Perceived Height
The upward component of the wash draws the eye toward the ceiling, making rooms feel significantly taller and more open than their actual dimensions.
Smooth, Even Line
Run continuously around a room, the NLP-4545 creates an unbroken band of light at the ceiling perimeter — a signature feature of high-end interiors.
Fast Corner Install
The triangular body sits naturally into any 90° corner without additional framing, brackets, or wall preparation. Clip in the strip, snap on the cover.
Surface Mount · No Ceiling Work Required
The NLP-4545 goes directly onto the corner surface — wall face down, ceiling face up. No recesses, no plasterboard reveals, no chasing. Once fixed, the LED strip is placed inside the channel and the PC cover clips on. A full room perimeter can be installed and lit within a single day.
