High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 30W/m, 1688 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 12mm wide, so it needs at least 14mm 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 12mm wide, so it needs a channel with at least 14mm inner width (12mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 1688 PU?
1688 PU: 2216, 300 LEDs/m, 24V, 12mm PCB, 3oz copper FPCB, cuttable 6LEDs/20mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
Which environments is this marine grade LED strip rated for?
Ingress protection for this model is listed in the datasheet. 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 #1688 PU?
Classic Series PU LED Light Strips | 12mm | 24V | 300LEDs | 20cut | #1688 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.
