Overview
2216 Special LED Strip Light | 6mm | 24V | 180LEDs | Arbitrary cut | #11474 is part of the DENO Special SMD Strips series, engineered around special application LED strip. Key specifications: 2216, 180LEDs/m, 24V, 6 PCB, 2oz copper FPCB, cuttable Arbitrary cutting. 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.
Description
A 6mm, 24V 2216 strip built for installers who need to cut and solder exactly where the fixture demands. Instead of isolated solder pads every few centimetres, the copper conductors run continuously along the top side of the FPCB and stay exposed, so power leads or jumpers can be soldered at any point along the run. The exposed copper is finished with immersion tin (ISn). Bare copper oxidises in air, and an oxidised pad wets poorly and is prone to cold joints; the tin layer keeps the pads solderable during storage and on site. With 180 LEDs/m the strip can be cut after every LED (5.55mm pitch), which suits tight aluminium profiles, joinery recesses and custom fixtures. 2oz copper FPCB, constant voltage, dimmable, up to 5m per run (10m with dual-end feed).
6mm 2216 strip with continuous top-exposed copper pads, immersion tin (ISn) finish, 1-LED cut and solder-anywhere wiring.

Why this strip solders and fits differently
Immersion Tin (ISn) Finish
Anti-oxidation for exposed copper
Bare copper tarnishes in air, and oxidised pads wet poorly and invite cold joints. An immersion tin layer protects the exposed copper so the pads stay solderable in storage and in the field.
Continuous Pads · Solder Anywhere
Feed power at any point
The top-side copper runs the full length of the strip rather than stopping at fixed cut marks. Solder feed wires, jumpers or mid-run power taps wherever the installation needs them.
1-LED Cut · 5.55mm Pitch
Arbitrary length
At 180 LEDs/m every LED is a cut point, so the strip can be trimmed to the millimetre for narrow profiles, joinery recesses and custom fixtures without a dark gap at the end.

Standard strip vs #11474
| Typical strip limitation | #11474 solution |
|---|---|
| Long cut units (25–100mm) leave dark gaps at the ends of short shelves and narrow profiles. | Cut at every LED (5.55mm pitch) — trim to the nearest 5.55mm, no dark gap at the cut end. |
| Tiny solder pads only at fixed cut marks are hard to reach with an iron inside tight recesses. | Continuous exposed pads along both edges — solder feed wires or jumpers at any position. |
| Bare exposed copper tarnishes in air; oxidised pads wet poorly and invite cold joints on site. | Immersion tin (ISn) finish (IPC-4554) protects the copper and keeps pads solderable. |

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 19.2W/m, 11474 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 6mm wide, so it needs at least 8mm 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 6mm wide, so it needs a channel with at least 8mm inner width (6mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
Why does #11474 use an immersion tin finish on its exposed pads?
Bare copper oxidises in air, which degrades solder wetting over time. #11474 coats its continuous exposed copper pads with immersion tin (ISn), a surface finish described in IPC-4554, which protects the copper from oxidation and keeps the pads solderable during storage and installation.
Where can I solder power leads on #11474?
The copper pads run continuously along the full strip and are exposed, so feed wires can be soldered at any point rather than only at fixed solder pads. This allows single-end, both-ends or mid-strip feeding to suit the installation.
Can I feed power in the middle of a #11474 run?
Yes. Because the conductors are exposed along the whole length, a mid-strip feed can be soldered at any LED position. Feeding from the middle or both ends shortens the electrical distance to roughly half the run, which reduces voltage drop. Maximum run is 5m single feed or 10m with dual-end feed.
How short can #11474 be cut, and does it leave a dark gap?
The strip can be cut at every LED. With 180 LEDs per metre the pitch is 5.55mm, so the strip can be trimmed to the nearest 5.55mm and the last LED sits close to the cut end, avoiding the dark gap common with long cut units in short shelves and narrow profiles.
How should I solder wires to the immersion-tin pads on site?
Use standard electronics soldering practice: a temperature-controlled iron, flux-cored solder and brief contact so the FPCB is not overheated. Follow the temperature profile published by your solder alloy manufacturer. The tin surface wets readily, so a short dwell is normally sufficient.
