Description
This 2835 CCT tunable LED strip light provides smooth color temperature transitions from 2700K to 6500K for versatile architectural ambiance control. Engineered with a single BIN under 3 SDCM, this strip delivers uniform color consistency across runs without requiring complex external controllers. Built on a durable 10mm PCB with 3oz copper foil, the 24V constant voltage design offers precise 50mm cutting increments for flexible installations. Ideal for commercial cove lighting, shelving, and accent projects, DENO delivers factory-direct wholesale project supply tailored for professional contractors.
We use 99.99% gold wire, large-size chips, and thickened FPCB, backed by a 5-year warranty.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 24W/m, 16474 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 16474?
16474: 2835, 240, 24V, 10 PCB, 3oz copper FPCB, cuttable 12LEDs/50mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
What colour temperatures and CRI options does this tunable white LED strip offer?
This model is supplied as a tunable white LED strip with high CRI options and the CCT range listed in the datasheet. DENO bins every batch for colour consistency, and custom CCT or spectrum combinations can be produced for project quantities.
Can DENO customise this tunable white LED strip for a project?
Yes. DENO manufactures the CCT 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 does a tunable white LED strip mix colour temperature?
Two LED channels, typically 2700K and 6500K, sit on the same FPCB and are dimmed against each other. Mixing the channels sweeps the white point along the black body line while total output stays even, which is how a CCT LED strip supports circadian and human centric lighting schedules.
