The NLP-1722 Trimless Deep Profile from Nucleo is a plaster-in aluminium LED channel built for a fully invisible, seamless light line in ceilings and walls. Its perforated mounting flange is designed to key directly into plaster or joint compound, so once skimmed and painted, the profile disappears completely into the surface — leaving only a clean, continuous strip of light with no visible aluminium edge, no trim, and no shadow line. Its deeper channel body gives it more room than standard shadow gap profiles, making it well suited to higher-output LED strips, COB strips, or multi-row strip setups where more depth and heat clearance are needed. This makes the NLP-1722 a strong choice for architects and contractors specifying true trimless lighting in high-end residential ceilings, hospitality interiors, retail displays, and feature walls where the light source must read as completely integrated into the architecture. Key features: The profile has an overall width of 57.3mm with a 22.6mm depth and a 17.3mm channel opening (15.1mm internal), giving it enough depth for a wide range of LED strip types and higher-lumen setups. It's built from solid extruded aluminium at 253 grams per meter for a rigid, sag-free run over long ceiling and wall lengths. The perforated flange along both edges is designed for plaster/joint-compound keying, letting it be fully skimmed over for a completely trimless finish. Each profile ships with a matching diffuser to spread the LED output evenly and remove hotspots along the channel. It's available in black and white finishes, so the visible channel base can be matched to the ceiling or wall color before plastering. Standard length is 2 meters per piece, packed 40 profiles and 40 diffusers per pack for project-scale ordering. Best used for: fully trimless ceiling and wall light lines, cove and perimeter lighting in high-end interiors, deep-channel applications needing higher-output LED strips, and any installation where the profile must disappear completely into a plastered surface. Note: LED strip sold separately; confirm compatible strip width, wattage, and CCT/lumen output before ordering.
