What counts as a high efficiency LED strip in lumens per watt?

In 2026 a mainstream 24V 2835 board sits around 120-140 lm/W. A high efficiency LED strip starts at roughly 160 lm/W and DENO's top binned 2835 and 2110 boards are measured at up to 200 lm/W at 4000K Ra 80, LM-79 tested at 25 degrees Celsius. The figure is light-source efficacy of the tape itself, measured without the driver, which is exactly how the ErP energy label is calculated.

What is the difference between high efficiency and high efficacy LED strip lights?

They describe the same measurement. Efficacy is the engineering term for lumens delivered per watt consumed; efficiency is how buyers and tender documents usually phrase it. DENO publishes lm/W per model so both audiences read the same number, and the ErP energy class printed on the reel is derived from it.

Which ErP energy class can a high efficiency LED strip reach?

Class C is achievable on the best-binned 2835 and 2110 boards above 180 lm/W, class D covers the 160-180 lm/W band and most well-specified architectural tape lands in class E. High-CRI 95+ and full spectrum builds drop one or two classes because phosphor conversion costs lumens. Every DENO datasheet states the measured class so it can be reproduced by a notified body.

Does a high efficiency LED strip run cooler and last longer?

Yes. Fewer watts per lumen means less heat into the FPCB, so junction temperature drops and L70 lifetime extends. Combined with 2 oz copper and a 99.9% pure copper foil the same brightness can be produced at 20-30% lower wattage, which also lets a single driver feed a longer run and keeps aluminium profiles below the touch-temperature limits used in hospitality projects.

How much energy does a high efficiency LED strip save on a large project?

Take 500 m of cove lighting at 10 hours a day. A 130 lm/W board delivering 1000 lm/m draws about 7.7 W/m; a 190 lm/W board delivers the same output at about 5.3 W/m. Across 500 m that is 1.2 kW saved, roughly 4,380 kWh a year, and it usually removes one driver and one circuit from the electrical schedule as well.

Can I get a high efficiency LED strip in 12V, 24V, 36V or 48V?

24V is the efficiency sweet spot and carries the full binned range. 12V is available where fixture space or existing drivers dictate it, at the cost of shorter single-feed runs. 36V and 48V constant-current boards keep the same lm/W while extending a single feed well past 20 m, which is where the real system efficiency gain shows up on long architectural lines.

What is an electroplated, non-die-cut FPCB?

A die-cut FPCB starts from rolled-annealed copper foil, typically 35 µm with 50 µm heavy variants, laminated to polyimide and mechanically punched. An electroplated non-die-cut FPCB grows the copper electrolytically onto the base film instead, so DENO's R2R circuits reach copper up to 105 µm or thicker with ±10 µm trace-width control. Compare the documented specifications rather than the process label alone.

Is a 50 m LED strip roll the same as a 50 m powered run?

No. The supplied reel length describes packaging; the maximum powered run length depends on the model's operating voltage, power per metre and feed arrangement. Reel formats are model-specific, so confirm both the available reel length and the required power-feed plan — including any mid-run injection — before you specify a long installation.

Which R2R LED strip suits SMD and SOB projects?

R2R SMD LED strip is the general-purpose choice for coves, shelves and architectural lines where discrete packages and standard cut units are appropriate. R2R SOB builds add a coated, dot-free luminous surface for exposed and close-viewing positions. Both use DENO's electroplated, non-die-cut FPCB; cutting interval, run length and power-feed requirements remain model-specific.

Description

Built on DENO's electroplated, non-die-cut R2R FPCB, this model has no intermediate PCB splice joints within its specified continuous length. Cutting interval, rated run length and feed positions remain model-specific.\nManufactured on DENO's roll-to-roll line, the FPCB stays continuous through the reel with no intermediate PCB splice joints between sections. Engineered with 128 LEDs per meter, this 2835 LED strip light delivers high light efficacy and uniform output with a 120-degree beam angle. The robust 10mm wide 3oz copper foil PCB ensures dependable thermal performance across an operating temperature range of -25°C to 40°C. Built on a constant voltage 24V circuit, the strip is fully dimmable with precise 62.5mm cuttable segments for seamless architectural lighting installations. One continuous placement pass across the whole roll keeps LED pitch and solder quality consistent for factory-direct wholesale project supply.

High-Power LED Strip: Heat Dissipation & Aluminum Channel Guide

At up to 21W/m, 3015 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 10mm wide, so it needs at least 12mm 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 10mm wide, so it needs a channel with at least 12mm inner width (10mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions

What are the key specifications of 3015?

3015: 2835, 128 LEDs/m, 24V, 10 PCB, 3oz copper FPCB, cuttable 8LEDs/62.5mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

What makes the construction of this roll to roll LED strip different?

It is built as a roll to roll LED strip on 3oz copper FPCB with a cutting unit of 8LEDs/62.5mm and an LED pitch of 7.8mm, so it holds its electrical and mechanical performance where standard strips fail.

Can DENO customise this roll to roll LED strip for a project?

Yes. DENO manufactures the Roll-to-Roll 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.

How long can this LED strip roll run in one continuous piece?

This model ships as a continuous roll-to-roll reel with no mid-reel solder joints, so custom single runs beyond the standard 5 m are available. Keep the run within a 3% voltage drop: lower power densities support up to 20 m single-end, higher densities need a both-ends or mid-feed connection. Use the DENO ProCalc voltage-drop tool to confirm the exact limit for your length.

Why choose a roll-to-roll strip over a standard 5 m LED strip reel?

The electroplated continuous FPCB keeps copper thickness uniform along the whole reel, so resistance stays low, brightness stays even end to end, and there are no pieced solder points that can fail during bending or long-run installation.
