Frequently Asked Questions
What are the key specifications of 9009?
9009: 2216 SMD, 300 LEDs/m, 24V, 10 PCB, 2oz copper FPCB, cuttable 6LEDs/20mm. 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 high density 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 high density LED strip can cover twice that length on one circuit when wired accordingly.
Can DENO customise this ultra high density LED strip for a project?
Yes. DENO manufactures the High Density LED 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 many LEDs per metre does a dotless LED strip need?
Visible dots depend on LED pitch, diffuser distance and transmittance. Above roughly 480 LEDs/m most diffusers give a continuous line at 10 mm depth, and the 700 LEDs/m high density LED strip stays dot free even behind a shallow, highly transmissive lens.
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.
High Density LED Strip — Buyer Questions
What counts as a high density LED strip?
Anything above roughly 120 LEDs per metre is normally sold as a high density LED strip. DENO builds high-density boards from 240 up to 700 LEDs/m, which puts the LED pitch between 4.2 mm and 1.4 mm — tight enough to read as a continuous line behind a shallow diffuser instead of a row of dots.
Is a 24V high density LED strip better than 12V?
For dense boards, yes in most cases. A 24V high density LED strip draws half the current of a 12V board at the same wattage, so voltage drop is far lower and single runs of 5–10 m stay even in brightness. DENO supplies 12V, 24V, 48V and mains-voltage versions of the same high-density layout; 12V is normally reserved for short cabinet runs or low-voltage furniture requirements.
Do you make a 5V high density LED strip?
Yes. 5V dense LED tape is built for USB-powered displays, shelving and addressable pixel projects where the controller is 5V-native. Because 5V boards lose voltage quickly, DENO limits standard runs to 1–2 m per feed, uses 2 oz or 35+70 μm copper, and adds per-segment constant-current ICs so the far end does not dim.

Can a high density RGB LED strip stay dot-free?
It can, but the pitch has to be tighter than a white board because each RGB package mixes three separate dies. DENO's high density RGB and RGBW builds place emitters at 2.1 mm–4.2 mm pitch so colour mixing completes within a few millimetres of the diffuser, which removes both the dot pattern and the rainbow fringing seen on standard 60 LEDs/m RGB tape.

What is a high density addressable LED strip used for?
High density addressable LED strip (pixel tape) is used for signage, media facades, stair effects and studio lighting where each LED or short segment must be controlled individually. DENO offers addressable builds with up to 700 pixels per metre in SPI protocols such as WS2812B, WS2815 and SK6812, with breakout points every cut unit for reliable data injection on long runs.
What makes the best high density LED strip lights?
Density alone is not enough. The best high density LED strip lights combine tight LED pitch with a 3-SDCM binning window, Ra 90+ (Ra 95+ for full-spectrum), 2 oz or heavier copper for thermal spreading, flicker-free constant-current drive and an FPCB rated for repeated bending. DENO ships photometric data, LM-80 chip data and a full test report with every OEM order so specifiers can verify these claims instead of trusting a datasheet number.

How dense can an ultra high density LED strip go?
DENO's ultra high density LED strip tops out at 700 LEDs per metre with a 1.4 mm pitch, drawing up to 30 W/m. Beyond that point a discrete SMD layout stops making sense thermally, and a SCOB (COB) emitter is the better route to a fully dotless line.

Can I order a custom high density LED strip?
Yes — LED count, pitch, CCT, CRI, PCB width from 3 mm, copper weight, cut unit and IP rating are all configurable on a custom high density LED strip. DENO is a manufacturer, not a reseller, so a non-standard density or a mixed-CCT dense board can be tooled from an existing FPCB stack-up without a new production line.

Is high density LED tape the same as a high density LED strip?
They are the same product under two names: “high density led tape” is the common UK/EU term for what North America calls a high density LED strip. DENO ships the identical dense FPCB boards to both markets — 240 to 700 LEDs/m, 3 mm to 12 mm widths, CE/UL/RoHS documentation — so the tape you specify in a UK cove detail is the same board as the strip specified in a US one.

Which dense LED tape suits under-cabinet lighting?
For under-cabinet work choose a dense board at 240–420 LEDs/m in a 5 mm to 8 mm width, 12V or 24V, with a short cut unit so the board matches each cabinet run exactly. At that density a 10 mm deep aluminium channel with a frosted diffuser already reads dot-free at normal worktop viewing distance.
What power supply do I need for a dense LED strip run?
Size the driver from the board wattage: multiply the W/m figure on the datasheet by the run length, then add 20–30 % headroom, so a 20 W/m board over 5 m needs a 100 W load on a 120–130 W constant-voltage driver. Match the driver voltage exactly (24V board, 24V driver), keep it constant-voltage rather than constant-current unless the board carries its own CC ICs, and check that the dimming protocol — TRIAC, 0–10V, DALI or PWM — is supported on both sides before ordering.
Does more LEDs per metre mean a brighter strip?
Not on its own. Brightness is lumens per metre, which is drive current times die count times efficacy — doubling the LED count while halving the current per die gives the same output with a smoother line, not twice the light. Read lm/m and W/m together: DENO dense boards run 8–24 W/m and 700–2600 lm/m, so pick the density for dot-free appearance and the wattage for the light level you actually need.
Can dense LED tape run on 36V or 48V supplies?
Yes. 36V and 48V builds exist specifically for long uninterrupted runs: at 48V the same wattage draws a quarter of the current of a 12V board, so a single feed can cover 15–20 m with even brightness and far fewer injection points. They need a matching SELV driver and, in most territories, the same low-voltage installation rules as 24V; DENO supplies 36V and 48V versions of the standard dense layouts on request.
Constant Current LED Strip — Buyer Questions
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.

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.
