Question 1

What are the key specifications of 14207-N?

Accepted Answer

14207-N: 2216, 420 LEDs/m, 24V, 10mm PCB, 3oz copper FPCB, cuttable 14LEDs/33.33mm. Full photometric data, wiring diagrams and test reports are available in the downloads section of this page.

Question 2

What makes the construction of this constant current IC LED strip different?

Accepted Answer

It is built as a constant current IC LED strip on 3oz copper FPCB with a cutting unit of 14LEDs/33.33mm and an LED pitch of 2.381mm, so it holds its electrical and mechanical performance where standard strips fail.

Question 3

Can DENO customise this constant current IC LED strip for a project?

Accepted Answer

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.

Question 4

How does a dim to warm LED strip behave when dimmed?

Accepted Answer

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.

Question 5

Does a constant current LED strip really eliminate voltage drop?

Accepted Answer

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.

Question 6

What counts as a high density LED strip?

Accepted Answer

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.

Question 7

Is a 24V high density LED strip better than 12V?

Accepted Answer

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.

Question 8

Do you make a 5V high density LED strip?

Accepted Answer

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.

Question 9

Can a high density RGB LED strip stay dot-free?

Accepted Answer

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.

Question 10

What is a high density addressable LED strip used for?

Accepted Answer

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.

Question 11

What makes the best high density LED strip lights?

Accepted Answer

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.

Question 12

How dense can an ultra high density LED strip go?

Accepted Answer

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.

Question 13

Can I order a custom high density LED strip?

Accepted Answer

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.

Question 14

Is high density LED tape the same as a high density LED strip?

Accepted Answer

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.

Question 15

Which dense LED tape suits under-cabinet lighting?

Accepted Answer

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.

Question 16

What power supply do I need for a dense LED strip run?

Accepted Answer

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.

Question 17

Does more LEDs per metre mean a brighter strip?

Accepted Answer

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.

Question 18

Can dense LED tape run on 36V or 48V supplies?

Accepted Answer

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.

Question 19

What is a dim to warm LED strip?

Accepted Answer

It is a strip that gets warmer in colour as it is dimmed down, the way a halogen lamp or a candle does, instead of holding one fixed colour temperature. The board carries two LED types in an alternating layout — a warm 1800K and a cooler 4000K — and the driver shifts the ratio between them as brightness falls, so the light travels from roughly 3000K at full output to about 1800K at the bottom of the dimming range.

Question 20

Which models are available and how dense are they?

Accepted Answer

Seven SMD boards cover the range. The 2216 high-density builds run 420 LEDs/m at 10 mm width (#14025, #14207-N) with a 33.3 mm cut and 7.2–18 W, or 224 LEDs/m with a 62.5 mm cut at 10 mm (#6942) and 6 mm (#17254, 7.7–15.36 W). The 2835 boards run 168 LEDs/m at 12 mm with an 83.3 mm cut (#5462 at 5.8–28.8 W, #5214 at 12–35 W). #4995 is a 12V 2216 board at 420 LEDs/m with a 14.28 mm micro-cut.

Question 21

What dimmer does it need, and how low does it go?

Accepted Answer

Any standard PWM dimmer on the DC side — TRIAC, 0–10V, DALI or a phase-cut driver — because the colour shift is produced by the strip's own circuit, not by the control system. The published range is smooth dimming from 100% down to roughly 1%, with the warmest point at the bottom. Use a dimmer rated above the run's connected load and keep the PWM frequency above 3 kHz where cameras are present.
