High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide
At up to 15W/m, 15917 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 5mm wide, so it needs at least 7mm 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.

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 5mm wide, so it needs a channel with at least 7mm inner width (5mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 15917?
15917: 3838, 120, DC24V, 5mm PCB, 3oz copper FPCB, cuttable 6LEDs/50mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
What colour temperatures and CRI options does this RGB LED strip lights offer?
This model is supplied as a RGB LED strip lights with high CRI options and the CCT range listed in the datasheet. DENO bins every batch for colour consistency, and custom CCT or spectrum combinations can be produced for project quantities.
Can DENO customise this RGB LED strip lights for a project?
Yes. DENO manufactures the RGB 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.
Should you choose RGB or RGBW LED strip lights?
RGB LED strip lights mix colour but produce a weak, tinted white. If the installation also needs usable white light for everyday use, choose RGBW or RGBCCT, which adds a dedicated white chip. Pure RGB is best where the strip is only ever a colour accent.
Which LED driver and run length suit #15917?
3838 RGB LED Strip Light | 5mm | 24V | 120LEDs | 50mm/cut | #15917 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.
