NUCLEO NLL-400D-COB — COB LED Strip Light (High CRI, 3mm, 24V DC) Product Description NUCLEO's NLL-400D-COB is a high-density COB (Chip-on-Board) LED strip built for architectural and interior lighting applications where a smooth, seamless glow matters. Unlike conventional SMD strips, the COB array eliminates visible LED dots and hotspots, delivering a continuous, linear line of light. With a Colour Rendering Index of >90, it renders colours accurately and naturally — ideal for retail displays, showrooms, and premium interior fit-outs. The slim 3mm PCB fits easily into narrow aluminium channels and cove details, and the strip can be cut at every 2cm for flexible, on-site sizing. Supplied by Mohit World under the NUCLEO brand, this strip is suited for architects, interior designers, lighting contractors, and electrical retailers looking for a dependable, dot-free lighting solution.

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.
