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.

The NLP-XF2 Shadow Gap Profile from Nucleo is a compact, T-shaped aluminium trim built to create crisp, clean shadow lines at ceiling-to-wall junctions and wall corners. Rather than a bulky cornice or visible molding, it leaves behind a thin, precise reveal line — the modern architectural detail favored in minimalist homes, offices, and retail interiors where walls and ceilings should meet without visible trim. It's one of the slimmest profiles in the Nucleo shadow gap range, designed to sit almost invisibly within the plaster or drywall joint. The result is a sharp, shadow-cast line that reads as a deliberate design detail rather than a construction seam — ideal for false ceiling edges, wall-to-wall corner joints, and drywall expansion/reveal lines. Key features: At just 20.5mm wide and 11.3mm high, the NLP-XF2 is built for the thinnest possible shadow gap, keeping the reveal line subtle and unobtrusive. It's made from extruded aluminium at a light 76 grams per meter, easy to handle, cut, and install without adding bulk to the wall or ceiling assembly. The T-profile design allows it to be recessed into plaster or drywall joints for a flush, professional finish. It comes in a black finish that reads as a clean shadow line rather than a visible trim strip. Standard length is 2 meters per piece, packed 250 profiles per pack — suited to large-scale ceiling and wall trim projects. Best used for: ceiling-to-wall shadow gap joints, wall corner reveal lines, drywall expansion joint trims, and minimalist architectural detailing where a clean line is wanted without visible molding. Note: This profile is supplied without a diffuser and is primarily a decorative reveal trim; check with the Nucleo team if you need a lit version with LED strip and diffuser for this application.

The NLP-XF17 Skirting Shadow Gap Profile from Nucleo is a slim, low-profile aluminium trim designed to replace the traditional visible skirting board with a clean, shadow-line reveal at the base of a wall or cabinet. Instead of a raised baseboard, it creates a thin recessed gap where the wall or cabinetry appears to “float“ just above the floor — a detail widely used in modern interiors, modular kitchens, and minimalist wall-to-floor junctions. Its T-shaped, flush-mount design lets it sit almost invisibly at the base of drywall, paneling, or cabinet toe-kicks, with just a slim reveal line visible from the front. Because the channel can house an LED strip, it doubles as a source of soft, indirect floor-level lighting — a warm glow that washes the floor from beneath the wall or cabinet edge, adding both a modern skirting detail and functional ambient or night lighting in kitchens, hallways, and living spaces. Key features: The profile has a compact footprint of 42mm in width by just 13.7mm in height, keeping the reveal line thin and unobtrusive. It's made from solid extruded aluminium at 157 grams per meter, light enough for easy handling and cutting on site while holding a straight, consistent line along skirting runs. It comes in a black finish that blends into shadow lines and floor junctions without drawing attention to the trim itself. Standard length is 2 meters per piece, packed 50 profiles per pack, suited to both small installations and larger project orders. Best used for: cabinet toe-kick and kickboard lighting, wall-to-floor shadow gap skirting, modern baseboard replacement, and hidden ambient or night lighting at floor level. Note: LED strip sold separately; confirm strip width and CCT/lumen output compatibility before ordering.
