Description
This 2216 LED strip light integrates 300 LEDs per meter on a robust 10mm, 3oz copper PCB for superior thermal performance. An integrated constant-current circuit eliminates brightness taper across 5m single-feed runs, providing uniform dot-free illumination ideal for architectural cove lighting. Precision cutting sections every 20mm paired with a tight 3.334mm LED pitch deliver smooth dimmable lighting in tight installation spaces. Engineered for demanding commercial environments, the 24V strip operates reliably between -25°C and 40°C across a 6W to 24W power range. DENO offers OEM custom lengths, specialized color temperatures, and tailored environmental protection ratings for wholesale project supply.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 18W/m, 14512-N 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.
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 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 14512-N?
14512-N: 2216, 300 LEDs/m, DC24V, 10mm PCB, 3oz copper FPCB, cuttable 6LEDs/20mm. 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 long run 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 long run LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra long run LED strip for a project?
Yes. DENO manufactures the Ultra-Long 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.
What limits how long an LED strip run can be?
Voltage drop and conductor current, not the LED itself. A long run LED strip combines low watts per metre, 2 oz or thicker copper and a higher bus voltage such as 24V, 36V or 48V to reach 20 m or more from one feed while staying inside a 3 percent drop.
Which LED driver and run length suit #14512-N?
2216 Long Run LED Strip Light | 10mm | 24V | 20mm/cut | 300LEDs | #14512-N is a constant-voltage DC24V product, so pair it with a CE or UL listed DC24V constant-voltage LED driver rated about 20% above the connected load. Maximum single run is 5m. 5m Single/10m Dual Input power. Feeding from both ends or mid-feeding halves the copper distance and roughly quarters the voltage drop.
