Description
Engineered with 420 LEDs per meter, this 2216 dim to warm LED strip light seamlessly shifts color temperature from 3000K down to 1800K. The 24V constant current circuit operates between 7.2W and 18W, offering full compatibility with standard TRIAC, PWM, and 0/1-10V dimming systems. Delivering up to 106lm/W with a high color rendering index of CRI 95, it produces smooth illumination across a 10mm wide PCB. Built with a heavy 3oz copper PCB, this flexible strip features precise cut points every 33.3mm to facilitate rapid architectural installation. Ideal for premium cove lighting and hospitality joinery, we offer factory-direct manufacturing and OEM custom lengths for wholesale project supply.
Dim To Warm Led Strip built for dim to warm smd strips projects.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 18W/m, 14025 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 14025?
14025: 2216, 420, 24V, 10 PCB, 3oz copper FPCB, cuttable 14LEDs/33.3mm. 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 high density 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 high density LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra high density LED strip for a project?
Yes. DENO manufactures the High Density LED 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 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.
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.
