Description
This 2216 Dim-to-warm LED strip light seamlessly shifts from cooler illumination to warmer tones as current decreases, creating adaptable architectural lighting environments. Featuring an ultra-narrow 6mm PCB width, this slim design provides flexible integration for compact spaces and refined linear installations. Built with a constant-current circuit and 3oz copper foil, the 24V system ensures balanced output across run lengths up to 5m. Densely arranged with 224 LEDs per meter, the strip allows precise cuttable sections every 14 LEDs or 62.5mm with a 120-degree beam angle. DENO delivers factory-direct wholesale project supply with OEM manufacturing capabilities to fulfill technical requirements for commercial contractors.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 15.36W/m, 17254 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.
Aluminum channels that fit this strip

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
What are the key specifications of 17254?
17254: 2216, 224 LEDs/m, 24V, 6mm PCB, 3oz copper FPCB, cuttable 14LEDs/62.5mm. 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 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 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.
How does a dim to warm LED strip behave when dimmed?
As output falls the white point shifts from about 3000K down to 1800K, mimicking an incandescent or halogen lamp at low levels. The shift follows a single dimming channel, so any standard 0-10V, DALI or PWM dimmer controls it and no second control wire is required.
