Polyurethane Indirect LED Lighting Cove Profile

The P81991 is a high-performance architectural element designed specifically for modern indirect lighting applications. By integrating seamlessly into transition zones between walls and ceilings, this profile conceals LED strips to create a soft, glare-free cove lighting effect. It offers architects and interior designers a reliable way to add depth and ambient warmth to contemporary spaces without visible light fixtures.

Manufactured from high-density rigid polyurethane with a density of 150-220 kg/m³, this profile delivers structural stability comparable to wood while remaining exceptionally lightweight. With dimensions of 141 mm in height, 111 mm in depth, and a standard length of 2400 mm, the profile provides a spacious internal cavity that accommodates various LED tape widths. Its closed-cell structure makes it moisture-resistant, helping to minimize warping or swelling in humid indoor environments like kitchens and bathrooms.

Visually, the P81991 features a smooth, unadorned surface with a graceful, sweeping curve that guides light upwards and outwards. The minimalist design is free of traditional ornate patterns, making it highly suitable for clean, contemporary, and transition styles. The precise geometry of the upper lip ensures that light is directed uniformly, eliminating hot spots and creating a balanced, professional illumination pathway.

This lighting profile is ideal for premium indoor projects. In residential designs, it enhances living rooms, bedrooms, and long hallways by visually elevating the ceiling height. In commercial environments, it serves as a sophisticated lighting solution for luxury hotel lobbies, modern office reception areas, upscale restaurants, and retail showrooms. It can also be utilized to crown custom TV background walls or headboard panels.

Installation is straightforward and far more efficient than working with heavy, fragile gypsum plaster or soft EPS foam alternatives. The lightweight sections are cut at 45-degree angles for corners, mounted using a polyurethane (PU) mounting adhesive, and secured mechanically with screws. The factory-applied primer coat prepares the surface for painting; however, we recommend applying a compatible paint-manufacturer primer before the final coat of water-based or synthetic paint to ensure full adhesion warranty. Once finished, it can be easily maintained by wiping with a damp cloth.
