Key specifications: 2835, 280, DC 48V, 20mm PCB, 3oz copper FPCB, cuttable 14LEDs/50mm. Every reel is produced on DENO's roll-to-roll line with 99.9% pure copper FPCB and ships CE, UL and RoHS compliant for architectural, retail and hospitality projects. OEM and ODM configurations of length, colour temperature and waterproofing are available on request.
Description
Engineered with 280 LEDs per meter in a dual-row layout, this 2835 LED strip light delivers continuous, high-output illumination for architectural lighting applications. The integrated constant current circuit design supports DC 48V operation, enabling extended single-feed runs up to 10 meters with minimal voltage drop. Built on a heavy-duty 20mm wide PCB with 3oz copper foil, the strip ensures superior heat dissipation and stable electrical performance. Featuring precise 50mm cutting increments and full dimming compatibility, this model is available for factory-direct wholesale project supply.
48v Led Strip Lights built for 48v smd strips projects.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 28.8W/m, 19810 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 20mm wide, so it needs at least 22mm 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.

Frequently Asked Questions
What are the key specifications of 19810?
19810: 2835, 280, DC 48V, 20mm PCB, 3oz copper FPCB, cuttable 14LEDs/50mm. 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 wide PCB LED strip be?
Maximum single run for this model is 10m. Feeding from both ends or using a mid-point tap halves the effective distance per segment, so a wide PCB LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this wide PCB LED strip for a project?
Yes. DENO manufactures the Wide 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 long can a 48V LED strip run from a single feed?
A 48V LED strip typically doubles the run length of an equivalent 24V LED strip at the same power density, with 20 to 40 m single-end runs common at low wattages. The exact limit depends on watts per metre and copper weight, so confirm it with the DENO voltage drop calculator before specifying.
Why use a wide LED strip PCB?
A 15 or 20 mm LED strip gives more copper area, so it dissipates heat better and carries more current. That is what allows high power builds above 25 W/m to run cooler, keep lumen maintenance high and support longer single feeds than a narrow board.
