Trimless Mud-In Recessed Linear Lighting
Architectural Plaster-In Linear Slot Lighting for Seamless Ceilings
Prillumen is a professional manufacturer of trimless mud-in recessed linear lighting systems designed for
drywall and plasterboard installations. Our mud-in profiles integrate directly into the ceiling structure, leaving nothing visible except a clean line of light.
By using a wide perforated plaster flange, the fixture becomes part of the architecture itself, eliminating traditional trim frames and creating a perfectly flush, minimalist ceiling.
Ideal for corporate offices, luxury retail environments, galleries, and modern residential interiors.
