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.

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

At up to 40W/m, 5871 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 20mm wide, so it needs at least 22mm 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.

Perguntas Frequentes

Quais são as principais especificações do 5871?

5871: 2835, 256 LEDs/m, DC 24V, PCB de 20mm, FPCB com cobre de 3oz, corte a cada 8LEDs/31.25mm. Dados fotométricos completos, diagramas de ligação e relatórios de ensaio estão disponíveis na seção de downloads desta página.

Qual pode ser o comprimento de um trecho único desta Fita de LED com PCB largo?

O comprimento máximo de um trecho único deste modelo é de 5M. A alimentação por ambas as extremidades ou por um ponto central reduz à metade a distância efetiva por segmento, de modo que uma Fita de LED com PCB largo pode cobrir o dobro desse comprimento em um único circuito quando conectada dessa forma.

A DENO pode personalizar esta Fita de LED com PCB largo para um projeto?

Sim. A DENO fabrica a série de Fitas SMD Largas como fornecedora OEM e ODM: comprimento do rolo, temperatura de cor, nível de IRC (CRI), largura do PCB, impermeabilização e identificação com marca própria podem ser especificados. Solicite um Orçamento para consultar o prazo de entrega e os preços do projeto.

Quanto uma Fita de LED de alta eficácia pode reduzir o consumo de energia?

A substituição de uma fita típica de 100 lm/W por uma Fita de LED de alto fluxo luminoso de 180 a 200 lm/W reduz aproximadamente à metade a potência necessária para o mesmo fluxo luminoso. Em uma instalação comercial extensa, isso também reduz a potência necessária do Driver / Fonte de Alimentação e ajuda a instalação a alcançar uma classe energética ErP melhor.

Por que usar um PCB largo em uma Fita de LED?

Uma Fita de LED de 15 ou 20 mm oferece maior área de cobre, dissipando melhor o calor e conduzindo mais corrente. É isso que permite que montagens de alta potência acima de 25 W/m operem com temperaturas mais baixas, mantenham elevada manutenção do fluxo luminoso e suportem trechos mais longos com alimentação única do que uma placa estreita.
