2835 Long Run LED Strip Light (#4274)
12mm · 24V · 60LEDs · 100cut
Model: 4274
Overview
12mm | 24V | 60LEDs | 100cut | #4274 | 2835 Ultra-long LED Strip Light is part of the DENO Ultra-Long SMD Strips series, engineered around ultra long run LED strip. Key specifications: 2835, 60LEDs/m, 24V, 12mm PCB, 3oz copper FPCB, cuttable 6LEDs/100mm. 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
2835 long LED strip lights — 24V DC, 60 LEDs/m on a 12mm, 3 oz copper board, cuttable every 100mm, constant-current circuit. Buyer decision: a low-power board for ambience-level long runs — up to 20 m of continuous strip with CC regulation keeping the line even, and the modest wattage lets one small driver cover the whole run. Good for hotel corridors and perimeter coves. Custom CCT, IP and length — request a factory quote.
Constant Current Ic Led Strip built for c.c. smd strips (ic regulated) projects.

Applications
- Cove, wall-wash & perimeter lighting — Coves, recesses, wall-wash details and ceiling perimeters where a continuous, uniform line of light is required.
- Showroom & hospitality display lighting — Shelving, display cases, reception desks and signage backlighting in shops, showrooms and hospitality spaces.
- Kitchen & wardrobe under-cabinet lighting — Kitchen, wardrobe and furniture task lighting where the strip stays hidden and only the light is seen.
- Long corridor & warehouse runs — 48V feeding lets one run cover long corridors, warehouse aisles and facade lines with fewer injection points and fewer power supplies.

Photometric Performance — CCT × CRI Efficacy Matrix
Peak measured luminous efficacy: 152.5 lm/W at 4000K, Ra 80, ErP energy class D (Grade DN (1st Tier)).
All values are measured at the stated power density and ambient 25 °C, reported as luminous efficacy in lumens per watt (lm/W), luminous flux per metre (lm/m) and the corresponding EU ErP (2019/2015) energy class.

Frequently Asked Questions
What are the key specifications of 4274?
4274: 2835, 60LEDs/m, 24V, 12mm PCB, 3oz copper FPCB, cuttable 6LEDs/100mm. 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 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.
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.
Constant Current LED Strip — Buyer Questions
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.

Long LED Strip Lights — Buyer Questions
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.

Do you supply extra long LED strip lights in 65.6 ft or 100 ft?
Yes. 65.6 ft (20 m) and 100 ft (30 m) are stock run lengths, and anything longer than 32 feet is supplied as one uncut board rather than two reels joined with a connector. Joints are the usual failure point on extra long LED strip lights, so removing them is the single biggest reliability gain on a large install.
