01
Dot-free output
A continuous phosphor layer fuses the chips into one even line, even at very close range.
Nucleo · LED Strips
One unbroken line of light. No dots, no compromise.
Nucleo COB LED strips replace the familiar row of bright points with a single, continuous glow. Fit one into a shallow cove, a tight joinery recess or an aluminium profile and the light reads as a clean architectural line.
Conventional dotted output
COB: continuous output
Why COB
The strip you stop noticing, and the light you do
A designer's biggest complaint about LED strip is rarely brightness. It is the visible dots that appear on a wall, a ceiling edge or a glossy surface when the diffuser sits too close. COB (chip-on-board) construction solves this at the source.
Many tiny chips sit under one continuous phosphor layer, so the strip emits a smooth, uniform ribbon of light. That makes it the natural choice wherever the strip is seen close up: shallow coves, under-cabinet recesses, wardrobe edges, stair risers and slim profiles.
Nucleo supplies COB strips for interior designers, architects and electrical contractors across India, with guidance on profile, driver and colour temperature for each project.
Specifier's note
Choose COB when the strip will sit within a few centimetres of a reflective or lightly diffused surface. If the viewing distance is long and the diffuser is deep, a standard SMD strip may be enough, and COB then becomes a quality upgrade rather than a necessity.
Features
What a COB strip does better
02
Shallow-cove friendly
Works in recesses where an SMD strip would show hotspots, so coves can be slimmer and joinery cleaner.
03
Flexible and cuttable
Bends around gentle curves and is cut at the marked points on the PCB to fit the exact run.
04
Pairs with profiles
Sits neatly in Nucleo aluminium channels for heat control, alignment and a finished edge.
05
Low-voltage safety
Runs from a constant-voltage driver, keeping installation safe in joinery and wet-adjacent areas.
06
Consistent colour
Uniform phosphor coating gives even colour along the length, which helps long continuous sightlines.
07
Dimmable systems
Pairs with compatible dimmable drivers for scene control and mood lighting.
08
Adhesive backing
Peel-and-stick backing speeds up fixing inside profiles and on clean, dry surfaces.
Installation tip
Clean the surface with isopropyl alcohol before fixing the adhesive, and press the strip along its full length. For long runs, feed power from both ends to keep brightness even from first metre to last.
Light that looks like it was drawn, not assembled.
When the fixture disappears and only the line remains, the architecture does the talking. That is what COB is for.
Applications
Where COB strips earn their place
Cove lighting
Slim ceiling coves with a smooth, hotspot-free wash on the ceiling.
Wardrobes and closets
Vertical edge strips that light clothing evenly without glare.
Kitchen under-cabinet
Even task light over counters with no dotted reflections on stone or glass.
Shelving and display
Concealed lighting under glass or timber shelves for retail and home displays.
Mirror surrounds
Soft frontal light around vanity mirrors and dressing tables.
Stair and step lighting
Continuous guide lines along risers and handrail recesses.
TV and feature walls
Back-lit panels and niches with a clean halo and no visible chips.
Hospitality and retail
Reception counters, bar fronts, showroom edges and signage outlines.
FAQ
COB LED strip: your questions answered
A COB strip packs many tiny LED chips under a continuous phosphor layer, so the output reads as one unbroken line. SMD strips use individual visible chips that can show as dots when the diffuser is shallow.
Not for the dot-free look, since COB removes the dots by itself. A profile is still recommended for heat dissipation, straight alignment, protection and a clean finished edge.
Yes. Flexible strips are cut only at the marked cut points on the PCB, and reconnected with solderless connectors or soldered joints.
Use a constant-voltage driver that matches the strip's rated voltage, with the total load including roughly 20 percent headroom. Confirm voltage and wattage per metre with Nucleo before ordering.
Feed power from both ends or from several points on long runs, use adequately thick cable between driver and strip, and keep individual runs within the limit recommended for the strip's voltage.
Yes. Because there are no individual dots, COB works well where the strip sits close to the diffuser or is seen from a short distance.
Warm white suits hospitality, bedrooms and living spaces. Neutral white suits kitchens, retail and workspaces. Keep one colour temperature consistent across a continuous sightline.
