Frequently Asked Questions
What are the key specifications of 17254?
17254: 2216, 224 LEDs/m, 24V, 6mm PCB, 3oz copper FPCB, cuttable 14LEDs/62.5mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.
How long can a single run of this ultra narrow LED strip be?
Maximum single run for this model is 5m. Feeding from both ends or using a mid-point tap halves the effective distance per segment, so a ultra narrow LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra narrow LED strip for a project?
Yes. DENO manufactures the Ultra-Narrow 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 narrow can a thin LED strip be?
DENO builds down to a 3 mm wide FPCB. A 3 mm LED strip fits aluminium channels, cabinet reveals, shelf edges and slim architectural slots where an 8 or 10 mm board cannot be hidden, while still carrying 2 oz copper for stable long runs.
How does a dim to warm LED strip behave when dimmed?
As output falls the white point shifts from about 3000K down to 1800K, mimicking an incandescent or halogen lamp at low levels. The shift follows a single dimming channel, so any standard 0-10V, DALI or PWM dimmer controls it and no second control wire is required.
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.
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.
Does a constant current LED strip dim without flicker?
It does when the driver is matched to it. Linear CC ICs dim smoothly on PWM down to about 1%, and at 16 kHz+ PWM the run is flicker-free on camera (low Pst LM and SVM). Analogue dimming of a CC board is not recommended below 20% because the IC needs headroom.

How long can a constant current LED strip run be?
Up to 20 m and beyond on 24V or 48V builds with 2 oz copper, versus 5 m for a comparable constant-voltage board. The practical limit becomes the copper's current-carrying capacity and thermal design rather than perceived brightness fall-off.
Can I order a custom constant current LED strip?
Yes — segment length, drive current, voltage, LED density, CCT/CRI, PCB width and copper weight are all configurable, and CC regulation can be combined with high-density, ultra-narrow or full-spectrum layouts on the same board.

Ultra Narrow LED Strip — Buyer Questions
Can a 3mm LED strip still be high density?
Yes. Micro packages such as 1808, 2110 and 2216 allow 240–480 LEDs/m on a 3–5 mm board, so a narrow reveal can still be dot-free behind a shallow diffuser. Above that density the width usually has to grow to 8 mm for thermal reasons.

What is the cut unit on an ultra-narrow LED strip?
Cut intervals typically run from 12.5 mm to 50 mm depending on voltage and density, and micro-cut versions shorten this further for exact millwork lengths. Ask for the cut unit in the quote — it decides how closely the finished run matches the drawing.

Can I order a custom width LED strip?
Yes — PCB width from 3 mm, LED density, CCT and CRI, copper weight, cut unit, IP class and connector are all configurable. DENO is a manufacturer, so a non-standard width is tooled from an existing FPCB stack-up instead of being ruled out.
