Description
This ultra-dense 2110 multi-line LED strip light packs 1120 LEDs per meter on a 12mm 2oz copper PCB for architectural lighting. Operating on a 24V constant voltage circuit, this fully dimmable strip supports an efficient power range of 2.4W to 20W. A tight 1.7mm LED pitch with 120-degree beam spread allows convenient cutting every 14 LEDs or 12.5mm intervals. Available in standard 5M reels for wholesale project supply, each strip reliably operates in temperatures from minus 25 to 40 degrees Celsius.
Micro Cut Led Strip built for micro-cut smd strips projects.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 27W/m, 3702 is a high-power SMD LED strip. Above roughly 14.4W/m the tape can no longer shed its own heat through the FPC alone — an aluminum channel is part of the luminaire, not an accessory.
Why high-wattage strips need a heat sink
- Aluminum conducts heat roughly 30× faster than the plastics, MDF or gypsum a strip is usually stuck to, so a bare high-power run traps heat under the tape.
- LED lifetime (LM-80 / TM-21) is driven by solder-point temperature Tc. Keeping Tc inside the datasheet limit — DENO strips are rated Tc ≤ 75°C — is what preserves the rated L70 lifetime and colour stability.
- Never run 14.4W/m or more coiled on the reel, inside a sealed plastic diffuser, or directly on wood, wallpaper or foam.
Sizing rule: FPC width vs channel inner width
- Channel inner width ≥ FPC width + 2mm. This strip is 12mm wide, so it needs at least 14mm of inner width.
- The 2mm clearance absorbs extrusion tolerance and lets the tape be seated or replaced without scraping the side walls or the wiring.
- A frosted or opal PC cover then diffuses the higher lumen output into an even, dot-free line instead of visible hot spots.

Recommended LED Channels
Mount this LED strip in a DENO LED aluminum profile for heat dissipation, physical protection and diffused, dot-free output.
This strip is 12mm wide, so it needs a channel with at least 14mm inner width (12mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 3702?
3702: 2110, 1120 LEDs/m, 24V, 12mm PCB, 2oz copper FPCB, cuttable 14LEDs/12.5mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
How long can a single run of this ultra high density LED strip be?
Maximum single run for this model is 5M. Feeding from both ends or using a mid-point tap halves the effective distance per segment, so a ultra high density LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra high density LED strip for a project?
Yes. DENO manufactures the High Density LED Strips series as an OEM and ODM supplier: reel length, colour temperature, CRI grade, PCB width, waterproofing and private labelling can all be specified. Request a quote for lead time and project pricing.
How many LEDs per metre does a dotless LED strip need?
Visible dots depend on LED pitch, diffuser distance and transmittance. Above roughly 480 LEDs/m most diffusers give a continuous line at 10 mm depth, and the 700 LEDs/m high density LED strip stays dot free even behind a shallow, highly transmissive lens.
How short can you cut a micro-cut LED strip?
Cut points come as close as 12.5 mm, against 50 to 100 mm on a conventional cuttable LED strip. Short segments matter in cabinets, stair nosings, signage letters and display cases where a standard cut interval would leave a dark gap at the end of the run.
