Overview
2020 Roll-to-Roll LED Strip Light | 10mm | 24V | 256LEDs | 31.25mm/cut | #16778 is part of the DENO Roll-to-Roll SMD Strips series, engineered around roll to roll LED strip. Key specifications: 2020, 256LEDs/m, 24V, 10mm PCB, 2oz copper FPCB, cuttable 8LEDs/31.25mm, IP20, CRI Ra≥80. Every reel is produced on DENO's roll-to-roll line with 99.9% pure copper FPCB and ships CE, UL and RoHS compliant for architectural, retail and hospitality projects. OEM and ODM configurations of length, colour temperature and waterproofing are available on request. This model uses DENO's electroplated, non-die-cut R2R FPCB, with no intermediate PCB splice joints inside the specified continuous length. Cutting interval, rated run length and planned feed positions remain model-specific.
Description
Built on DENO's electroplated, non-die-cut R2R FPCB, this model has no intermediate PCB splice joints within its specified continuous length. Cutting interval, rated run length and feed positions remain model-specific.\nContinuous roll-to-roll manufacturing removes the periodic board joints of sheet-to-sheet tape, leaving no intermediate PCB splice joints inside the reel. High-density 2020 SMD packaging delivers 256 LEDs per meter and 1200 lumens of uniform illumination on a 24V constant voltage circuit. A 10mm wide 2oz copper FPCB provides superior thermal management and structural durability for reliable operation in commercial environments. Tiny 2020 emitters are mounted in a single continuous SMT pass, holding pitch accuracy and single-bin colour consistency across the roll. Precise cut points every 31.25mm make this IP20 LED strip light adaptable for custom architectural lighting and tailored OEM orders.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 15W/m, 16778 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 10mm wide, so it needs at least 12mm 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 10mm wide, so it needs a channel with at least 12mm inner width (10mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 16778?
16778: 2020, 256LEDs/m, 24V, 10mm PCB, 2oz copper FPCB, cuttable 8LEDs/31.25mm, IP20, CRI Ra≥80. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
What makes the construction of this roll to roll LED strip different?
It is built as a roll to roll LED strip on 2oz copper FPCB with a cutting unit of 8LEDs/31.25mm and an LED pitch of 3.906mm, so it holds its electrical and mechanical performance where standard strips fail.
Can DENO customise this roll to roll LED strip for a project?
Yes. DENO manufactures the Roll-to-Roll SMD 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 long can this LED strip roll run in one continuous piece?
This model ships as a continuous roll-to-roll reel with no mid-reel solder joints, so custom single runs beyond the standard 5 m are available. Keep the run within a 3% voltage drop: lower power densities support up to 20 m single-end, higher densities need a both-ends or mid-feed connection. Use the DENO ProCalc voltage-drop tool to confirm the exact limit for your length.
Why choose a roll-to-roll strip over a standard 5 m LED strip reel?
The electroplated continuous FPCB keeps copper thickness uniform along the whole reel, so resistance stays low, brightness stays even end to end, and there are no pieced solder points that can fail during bending or long-run installation.
