High Density LED Strips | DENO LED

Shallow coves and slim aluminium channels

When the diffuser sits 6–12 mm above the board, standard 60 LEDs/m tape shows a visible dot pattern. A 240–480 LEDs/m layout with 2.1–4.2 mm LED pitch closes the gap so the extrusion reads as a continuous line of light even at a 1:1 depth-to-pitch ratio.

Retail display cases and joinery reveals

Shelf lighting is viewed from under a metre away. Dense boards with Ra 90+ and a 3-SDCM binning window keep merchandise colour consistent across a run of cases, while the tight pitch removes the scalloping that draws attention to the fixture instead of the product.

Architectural linear profiles and wall grazing

Continuous perimeter runs expose every join and every dot. A tight LED pitch lets specifiers drop diffuser depth, reduce the profile height, and still pass a close-range visual inspection on handover.

Film, studio and photography fill light

Cameras resolve dot patterns that the eye forgives. Dense boards with a high LED count per metre plus flicker-free constant-current drive give a clean, even wash on set, with TLCI/TM-30 friendly full-spectrum options available on request.

LED count and LED pitch (240–700 LEDs/m, 1.4–4.2 mm)

LED pitch — the centre-to-centre distance between emitters — is the parameter that actually controls dot visibility. As a rule of thumb, mounting depth should be at least equal to the pitch. At 700 LEDs/m the 1.4 mm pitch stays dot-free behind a 2 mm diffuser.

Power density and thermal headroom (up to 30 W/m)

More LEDs per metre means more heat per metre. DENO specifies 2 oz (70 µm) copper foil and, for the densest builds, 35 + 70 µm double-layer stacks so junction temperature stays in range and lumen maintenance holds over L90 targets. Always mount high-power dense tape in an aluminium profile.

Voltage, run length and voltage drop (12 V / 24 V / 48 V)

A dense board draws more current per metre, so 24 V or 48 V constant-voltage — or a constant-current linear IC per segment — protects the far end of the run from brightness fall-off. Single-end, both-ends and mid-feed wiring are all supported; both-ends and mid-feed halve the effective distance.

Cut unit, CCT and CRI options

Cut intervals scale with density: typical units are 12.5–50 mm, so dense boards still fit exact millwork dimensions. CCT is available from 1800 K to 6500 K, plus tunable white and full-spectrum, with Ra 90, Ra 95 and Ra 98 grades and 1–3 SDCM consistency.

240–320 LEDs/m — general architectural coves

The efficient starting point for a compact led strip in a 10 mm-plus channel with a frosted diffuser. Best lumen-per-watt balance and the widest CCT and CRI availability.

480 LEDs/m — display cases and close-viewed reveals

The most-specified density for retail joinery: dot-free at 4–6 mm depth, with cut units short enough for shelf-length runs and enough headroom to dim smoothly to 1%.

700 LEDs/m — the densest layout, for zero-depth builds

For plaster-in details, ultra-slim profiles and camera-facing installations where the diffuser sits directly on the board. Requires an aluminium heat path and, in most cases, 24 V or 48 V feed.

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.
