What is a constant current LED strip?

A constant current LED strip carries a linear CC driver IC on the board that holds a fixed current through each segment regardless of the input voltage seen at that point. Brightness therefore stays flat along the run, instead of falling off with voltage drop the way a plain constant-voltage strip does.

Constant current vs constant voltage LED strip — which is better?

Constant voltage is cheaper and fine for short runs under 3 m. Constant current is the right choice whenever the run is long, the copper is thin, the input voltage is unstable, or the installation is camera-facing — the IC absorbs supply variation and keeps every metre at the same luminous flux.

Can a constant current LED strip be powered from both ends or mid-feed?

Yes. Because regulation happens per segment, DENO's CC boards accept single-end, both-ends and any mid-strip tap. Both-ends and mid-feed wiring halve the effective feed distance, which is how a single driver covers a long corridor or perimeter cove.

Does a constant current LED strip dim without flicker?

It does when the driver is matched to it. Linear CC ICs dim smoothly on PWM down to about 1%, and at 16 kHz+ PWM the run is flicker-free on camera (low Pst LM and SVM). Analogue dimming of a CC board is not recommended below 20% because the IC needs headroom.

How long can a constant current LED strip run be?

Up to 20 m and beyond on 24V or 48V builds with 2 oz copper, versus 5 m for a comparable constant-voltage board. The practical limit becomes the copper's current-carrying capacity and thermal design rather than perceived brightness fall-off.

Can I order a custom constant current LED strip?

Yes — segment length, drive current, voltage, LED density, CCT/CRI, PCB width and copper weight are all configurable, and CC regulation can be combined with high-density, ultra-narrow or full-spectrum layouts on the same board.

How long can a long LED strip run be on a single power feed?

A standard 24V constant-voltage tape is limited to about 5 m before the far end visibly dims. DENO's long-run boards combine 2 oz to 3 oz copper, 24V or 48V input and per-segment constant-current ICs, which takes a single feed to 20 m, and up to 50 m on 48V builds, with no measurable fall-off between the first and last metre.

What are the longest LED light strips DENO manufactures?

Standard reels ship at 5 m, 10 m, 15 m, 20 m and 30 m, and OEM orders are produced as one continuous 50 m board with no mid-reel solder joint. Roll-to-roll plating is what makes that possible: the copper is deposited continuously, so length is not capped by panel size the way it is on die-cut FPCB.

Can long LED light strips be cut to an exact length for a room or kitchen?

Yes. Cut units run from 12.5 mm to 100 mm depending on voltage and density, so a run can be trimmed to a drawing dimension on site, and DENO also pre-cuts and pre-wires to length at the factory for room, cove and kitchen installations. Ask for the cut unit in the quote — it decides how closely the finished line matches the millwork.

2835 Classic Long Run LED Strip Light (#11056)

11056 long led strip — 24V, cuttable every 50mm, 8mm FPCB width, 2835 LEDs, 140 LEDs/m, IP20

Overview

2835 Classic LED Strip Light | 8mm | 24V | 140LEDs | 50mm/cut | #11056 is part of the DENO Ultra-Long SMD Strips series, engineered around ultra long run LED strip. Key specifications: 2835, 140LEDs/m, DC 24V, 8mm PCB, 3oz copper FPCB, cuttable 7LEDs/50mm. 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

Engineered with 140 LEDs per meter on a narrow 8mm PCB, this 2835 LED strip light operates on DC 24V power. Integrated constant-current IC design maintains uniform brightness across single-feed runs up to 10 meters without visible voltage drop or mid-run wiring. Built with heavy 3oz copper foil for optimal thermal management, the flexible board features convenient 50mm cut increments and a 120-degree beam angle. Fully dimmable with a 60mm minimum bend diameter, the strip delivers seamless illumination for continuous architectural cove lighting, corridors, and retail perimeters. DENO provides factory-direct wholesale production with OEM custom reel lengths, color temperatures, and specialized protection ratings for global project contractors.

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 24W/m, 11056 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.

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 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 11056?

11056: 2835, 140LEDs/m, DC 24V, 8mm PCB, 3oz copper FPCB, cuttable 7LEDs/50mm. 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 10m. 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.

Does a constant current LED strip really eliminate voltage drop?

Voltage still drops along the copper, but the per-segment constant current IC holds LED current fixed until the local voltage falls below its dropout point. Brightness therefore stays even end to end, and power can be injected at one end, both ends or any mid point of the run.

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.
