7923-PU 2835 High Light Efficacy PU LED Strip Light | 10mm | 24V | 128LEDs | 62.5mm/cut | #7923-PU — 24V, cuttable every 62.5mm, 10mm FPCB width, 2835 LEDs, 128 LEDs/m, 1800-6500

Overview

2835 High Light Efficacy PU LED Strip Light | 10mm | 24V | 128LEDs | 62.5mm/cut | #7923-PU is part of the DENO Marine Grade SMD Strips series, engineered around marine grade LED strip. Key specifications: 2835, 128, 24V, 10mm PCB, 3 oz copper FPCB, cuttable 8LEDs/62.5mm, IP68PU, CRI Ra≥80 , Ra≥90 , Ra≥95 , FS. 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

This 2835 PU LED strip light utilizes high-efficacy emitters delivering up to 1929 lumens per meter for professional linear illumination. Advanced polyurethane potting provides IP68 waterproof ingress protection and UV resistance to reliably safeguard internal components against outdoor elements. Engineered with a durable 3 oz copper PCB and 24V constant current circuitry, each section is cleanly cuttable every 62.5mm. The fully sealed construction is ideal for exterior architectural facade lighting, outdoor pathway illumination, and decorative landscape projects. DENO delivers factory-direct wholesale project supply with OEM custom lengths and multiple color rendering options to meet engineering specifications.

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 19.2W/m, 7923-PU 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.

Ingress protection for this model is IP68PU. As a marine grade LED strip 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 marine grade LED strip for a project?

Yes. DENO manufactures the Marine Grade 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 makes an LED strip marine grade?

Marine LED strip lights need IP67 or IP68 encapsulation, salt-mist resistant coating, tinned copper conductors and UV stable silicone. These boat LED strip lights are built for continuous saltwater spray and vibration rather than the light splash duty a standard waterproof strip is rated for.

Which LED driver and run length suit #7923-PU?

2835 High Light Efficacy PU LED Strip Light | 10mm | 24V | 128LEDs | 62.5mm/cut | #7923-PU is a constant-voltage 24V product, so pair it with a CE or UL listed 24V 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.
