Description

Engineered with 240 LEDs per meter on a 10mm PCB, this 2835 LED strip light delivers smooth, high-density illumination for linear architectural lighting. Operating on 24V constant voltage, the flexible tape offers precise 33.33mm cutting intervals and smooth dimming for OEM custom lengths. Built with 3oz copper foil, the board maintains superior thermal management across continuous runs up to 5 meters with a 60mm bend diameter. Solid copper lead frames and 99.9% purity gold wire encapsulation protect the SMD emitters against mechanical stress during field installation.

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 18W/m, 3493 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 3493?

3493: 2835, 240 LEDs/m, 24V, 10mm PCB, 3oz copper FPCB, cuttable 8LEDs/33.33mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

Which environments is this high efficacy LED strip lights rated for?

Ingress protection for this model is listed in the datasheet. As a high efficacy LED strip lights it is specified for the duty listed in the datasheet, and DENO can supply alternative coatings, sleeves or IP68 potting for harsher installations.

Can DENO customise this high efficacy LED strip lights for a project?

Yes. DENO manufactures the High Light Efficacy 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 much can a high efficacy LED strip cut energy use?

Moving from a typical 100 lm/W strip to a 180 to 200 lm/W high lumen LED strip roughly halves the wattage needed for the same lumen output. Over a long commercial run this also lowers the required driver size and helps the installation reach a better ErP energy class.
