Question 1

How does a dim to warm LED strip achieve its color temperature shift?

Accepted Answer

Dim to warm LED strips integrate multiple LED chip types, typically 3000K and 1800K, onto a single FPCB. A specialized driver or controller dynamically adjusts the power supplied to each chip type. As the overall brightness is reduced, the controller proportionally increases the power to the warmer (1800K) chips while decreasing power to the cooler (3000K) chips, creating a smooth transition in correlated color temperature.

Question 2

What are the typical CRI and SDCM specifications for DENO LED's dim to warm strips?

Accepted Answer

DENO LED's dim to warm strips are engineered for high color fidelity, featuring a typical Color Rendering Index (CRI) of Ra>90. We utilize 1 SDCM (Standard Deviation of Color Matching) binning for all LED chips, ensuring minimal color variation between individual LEDs and consistent color temperature across the entire strip length, which is critical for professional installations.

Question 3

Can dim to warm LED strips be cut to custom lengths, and what is the smallest cut unit?

Accepted Answer

Yes, DENO LED's dim to warm strips are designed for field customization. The cutting points are clearly marked on the FPCB, typically every 50mm or 100mm, depending on the specific model and LED pitch. This allows for precise length adjustments to fit various project requirements, facilitating integration into custom fixtures or architectural details.

Question 4

What control protocols are compatible with DENO LED's dim to warm systems?

Accepted Answer

Our dim to warm LED strips are compatible with standard low-voltage dimming protocols, including PWM (Pulse Width Modulation) based constant voltage dimmers. For advanced control and integration into building management systems, DALI and DMX control options are available through compatible drivers and interfaces. This offers flexibility for various project scales and control sophistication levels.

Question 5

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 6

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 7

Is it the same as a CCT tunable strip?

Accepted Answer

No, and the difference matters when specifying. A tunable white strip needs a two-channel controller and lets the user set any colour temperature at any brightness. A dim to warm board follows a fixed curve tied to the dimming level: one channel, one ordinary dimmer, no separate colour control. That makes it simpler to wire into restaurants, hotel rooms and residential schemes where the client wants the warm-glow effect without teaching anyone a control system.

Question 8

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 9

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.

Question 10

How long can one run be, and where is it usually installed?

Accepted Answer

All seven boards are rated 5 m from a single feed and 10 m fed from both ends, on 2 oz or 3 oz copper. In practice they go into hospitality and residential work where the mood changes through the evening: cove and coffer lighting, under-cabinet and shelf lines, headboard and bedside details, restaurant and bar joinery, and gallery display cases where a warm low setting flatters finishes.

Question 11

Can the warm end, CRI or board width be customised?

Accepted Answer

Yes. The warm and cool chip pairing, the dimming curve's end points, CRI grade, PCB width, LED pitch, cut unit, IP class and reel length are all configurable, and the same effect is available as a dot-free SOB build (#14207) at 420 LEDs/m on a 10 mm board with a 33.33 mm cut. DENO manufactures the FPCB in-house, so a custom pairing is tooled from an existing stack-up.
