High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 14.4W/m, 6891 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 5mm wide, so it needs at least 7mm 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 5mm wide, so it needs a channel with at least 7mm inner width (5mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 6891?
6891: 2216, 240 LEDs/m, 24V, 5mm PCB, 2oz copper FPCB, cuttable 6LEDs/25mm. 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 narrow 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 narrow LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra narrow LED strip for a project?
Yes. DENO manufactures the Ultra-Narrow 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 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 narrow can a thin LED strip be?
DENO builds down to a 3 mm wide FPCB. A 3 mm LED strip fits aluminium channels, cabinet reveals, shelf edges and slim architectural slots where an 8 or 10 mm board cannot be hidden, while still carrying 2 oz copper for stable long runs.
