2835 Long Run LED Strip Light (#7909)
8mm · 24V · 120LEDs · 41.67cut
Model: 7909
Overview
2835 Ultra-long LED Strip Light | 8mm | 24V | 120LEDs | 41.67cut | #7909 is part of the DENO Ultra-Long SMD Strips series, engineered around ultra long run LED strip. Key specifications: 2835, 120, 24V, 8 PCB, 3oz copper FPCB, cuttable 5LEDs/41.67mm. 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 24V 2835 LED strip light integrates 120 LEDs per meter on an 8mm wide 3oz copper PCB for reliable architectural lighting installations. Built-in constant-current circuit regulation eliminates visible voltage drop across single-feed run options of 5m, 10m, and 20m lengths. Engineered with a precise 41.67mm cutting pitch and a wide 120-degree beam angle, the dimmable design enables accurate field customization. The heavy copper board operates reliably across ambient temperatures from -25°C to 40°C while accommodating power demands from 3W to 35W. DENO provides factory-direct wholesale project supply with OEM custom lengths, specialized ingress protection, and tailored color temperatures upon request.
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 23W/m, 7909 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 8mm wide, so it needs at least 10mm 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 8mm wide, so it needs a channel with at least 10mm inner width (8mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions
What are the key specifications of 7909?
7909: 2835, 120, 24V, 8 PCB, 3oz copper FPCB, cuttable 5LEDs/41.67mm. 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 ultra long run LED strip be?
Maximum single run for this model is 5m/10m/20m. Feeding from both ends or using a mid-point tap halves the effective distance per segment, so a ultra long run LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra long run LED strip for a project?
Yes. DENO manufactures the Ultra-Long 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 limits how long an LED strip run can be?
Voltage drop and conductor current, not the LED itself. A long run LED strip combines low watts per metre, 2 oz or thicker copper and a higher bus voltage such as 24V, 36V or 48V to reach 20 m or more from one feed while staying inside a 3 percent drop.
Which LED driver and run length suit #7909?
2835 Long Run LED Strip Light | 8mm | 24V | 120LEDs | 41.67cut | #7909 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/10m/20m. 5m Single/10m Dual Input power | 10m Single/20m Dual Input power | 20m Single/40m Dual Input power Feeding from both ends or mid-feeding halves the copper distance and roughly quarters the voltage drop.
