This External Corner Plaster Profile is designed for seamless architectural lighting installations within plasterboard walls and ceilings. Featuring extended plaster wings and a centrally recessed LED channel, the profile integrates flush into surrounding surfaces to create clean uninterrupted light lines with a modern trimless appearance.
The profile incorporates a deep-set LED channel with a 12.5mm internal width, suitable for standard LED strip installations while helping reduce glare and improve lighting comfort. Its recessed lighting position creates soft indirect illumination and refined shadow line effects ideal for premium residential, retail, hospitality, and commercial interiors.
With a total width of 53mm and overall depth of 24mm, the integrated plaster flanges allow secure embedding into plasterboard for smooth concealed installation. The deep architectural design enhances the visual depth of the lighting while maintaining a minimalist finish.
The profile delivers smooth, uniform illumination with reduced visible LED spotting. Manufactured from high-quality aluminium, it provides excellent durability and efficient heat dissipation to maximise LED strip lifespan and maintain consistent lighting performance.
