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.

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.

Why do long strip lights get dimmer at the far end, and how is it fixed?

Copper resistance drops the supply voltage along the tape, so LEDs near the end of the run receive less drive current. Three fixes work together: raise the voltage (24V, 36V or 48V), raise the copper weight (2 oz or 3 oz), and add a linear constant-current IC per segment so each segment holds its current regardless of the local voltage it sees.

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

At up to 19.2W/m, 4490 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 4490?

4490: 2835, 112 LEDs/m, 24V, 10mm PCB, 3oz copper FPCB, cuttable 7LEDs/62.5mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

Which environments is this WAP waterproof LED strip rated for?

Ingress protection for this model is listed in the datasheet. As a WAP waterproof LED strip 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 WAP waterproof LED strip for a project?

Yes. DENO manufactures the DENO WAP 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.

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.

Is a coated waterproof LED strip better than a silicone sleeve?

The WAP nano-coating bonds to the board, so the strip keeps its original thickness, bend radius and heat dissipation while reaching IP67. A silicone sleeve adds bulk, traps heat and can yellow, though it remains the right choice for continuous immersion at IP68.
