Frequently Asked Questions
What are the key specifications of 7923?
7923: 2835, 128LEDs/m, 24V, 8mm PCB, 3 oz 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 constant current IC LED strip different?
It is built as a constant current IC LED strip on 3 oz 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 constant current IC LED strip for a project?
Yes. DENO manufactures the C.C. SMD Strips (IC Regulated) 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.
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.
High Efficiency LED Strip — Buyer Questions
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.

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.
