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.

Are there super bright LED strip lights in 12V, and when should I use 24V or 48V instead?

12V super bright LED strip lights exist but are limited to short runs: at 20 W/m a 12V board pulls 1.7 A per metre, so voltage drop dims the far end after 2–3 m. For architectural work DENO builds the wide boards in 24V and 48V, where the same wattage draws half or a quarter of the current and one feed covers 5–15 m. Where the fixture is 12V-native, keep the run short and feed each section separately.

Which is brighter — a wide multi-row board or a high-density single row?

For raw output, the wide multi-row board wins: rows multiply the flux while a single row is capped by LED pitch. For a dot-free line in a shallow reveal, high density wins. The two are combined on DENO's 36 mm and 64 mm boards, which run three or four dense rows at once, giving both an ultra bright LED strip face and an even luminance across the diffuser.

Can I order a custom width bright white LED strip?

Yes — board width, row count, LED density, CCT and CRI, copper weight, cut unit, IP class and connector are all configurable. Bright white LED strip lights are usually specified 4000K–6500K at Ra 90+ for workshops, cold rooms and signage; DENO tools these on the existing wide FPCB stack-ups, so a non-standard width is a production setup rather than a new product line.

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

At up to 28W/m, 4944 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 15mm wide, so it needs at least 17mm 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 15mm wide, so it needs a channel with at least 17mm inner width (15mm + 2mm clearance). Every profile below meets that.

Frequently Asked Questions

What are the key specifications of 4944?

4944: 2835, 160 LEDs/m, 24V, 15mm PCB, 3oz copper FPCB, cuttable 8LEDs/50mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

Which environments is this high efficacy LED strip lights rated for?

Ingress protection for this model is listed in the datasheet. As a high efficacy LED strip lights it is specified for the duty listed in the datasheet, and DENO can supply alternative coatings, sleeves or IP68 potting for harsher installations.

Can DENO customise this high efficacy LED strip lights for a project?

Yes. DENO manufactures the High Light Efficacy 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 much can a high efficacy LED strip cut energy use?

Moving from a typical 100 lm/W strip to a 180 to 200 lm/W high lumen LED strip roughly halves the wattage needed for the same lumen output. Over a long commercial run this also lowers the required driver size and helps the installation reach a better ErP energy class.

Which LED driver and run length suit #4944?

15mm | 24V | 160LEDs | 50mm/cut | #4944 | 2835 High Light Efficacy Multi-Line LED Strip Light 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. 5m Single / 10m Dual Input power. Feeding from both ends or mid-feeding halves the copper distance and roughly quarters the voltage drop.
