How do you keep white genuinely white?
A dedicated white channel and DUV fine-tuning help avoid the blueish or magenta cast that can appear when RGB channels are used to imitate white.
RGBW Precision Control · Powered by Koolmesh
Colour that stays true.
Control that stays simple.
Create accurate white light, repeatable colour and project-ready scenes across integrated luminaires, LED strips and DALI DT8 installations.
Start with the project result
Colour should add value—not another control problem.
Most hospitality, retail, workplace and façade projects do not need a light show. They need dependable white light, selected colour accents and scenes that can be commissioned once and recalled consistently.
Hytronik brings those requirements into one Koolmesh workflow—without forcing every project into a complex DMX-style infrastructure.How do you keep matching luminaires consistent?
RGBW, xyY and black-body-curve control provide different levels of precision, from fast scene creation to exact chromaticity matching.
How do you commission the whole project efficiently?
Detect, group, calibrate and copy settings through Koolmesh, then connect scenes to schedules, inputs or sensors.
True white
Protect everyday visual quality and merchandise, task or hospitality lighting.
Brand colour
Fine-tune deliberate colour points instead of relying on approximate presets.
Repeatable scenes
Recall the same atmosphere across luminaires, zones and operating periods.
One workflow
Commission, group, automate and hand over through Koolmesh.
Why simple colour becomes project friction
The brief is simple. The hidden detour is not.
Most clients want dependable white light, one controlled accent and scenes that happen on time. Conventional RGBW architecture can add layers the client never asked for.
Three useful lighting outcomes—not a complicated light show.
Clean whiteSelected colourTimed scenes
The hidden detourEvery extra layer creates another place for cost, colour or handover to drift.
More equipment
Extra boxes, gateways and channel wiring raise cost and coordination risk.
Visible colour drift
RGB-only white and repeated manual tuning can leave luminaires mismatched.
Slow handover
Scene-by-scene corrections stretch commissioning and are harder to protect.
Hytronik direct pathOne Koolmesh commissioning layer, three installation paths and repeatable settings across the project.
Original Koolmesh App interface
Three ways to define colour—inside one familiar control layer.
Choose the simplest method that achieves the design intent. Everyday scenes do not need laboratory-level input, while demanding projects can move into exact colour points and white-spectrum refinement.
Koolmesh colour control
RGBW Preferences
Set and save brightness and colour contribution for every channel, then recall neutral, warm or expressive scenes in seconds.
xyY Coordinate Control
Work in the CIE colour space when the same specified hue must be reproduced across fixtures, groups or spaces.
Black-Body Curve & DUV
Follow a natural white-light path, then adjust DUV to refine tint and reduce unwanted green or magenta shifts.
The available colour dimensions, adjustment range and commissioning options depend on the selected Hytronik product, connected lighting hardware and project requirements.
Choose by installation type
One colour strategy. Three practical ways to build it.
The control experience can stay consistent while the hardware changes to suit new luminaires, existing LED strips or a professional DALI DT8 installation.
PATH 01 · CONSTANT CURRENT
Precision engineered into the luminaire.
For premium integrated fixtures where matching colour, smooth low-level dimming and long-term stability matter.
- RGBW, xyY and DUV fine adjustment
- Uniform output with fewer manual corrections
- Smooth colour mixing at low brightness
- Architectural, museum, hospitality and corporate projects
PATH 02 · CONSTANT VOLTAGE / PWM
Add colour to strips without rebuilding the space.
For decorative and retrofit projects where RGBW LED strips are already part of the design or need a fast upgrade.
- Placed between the power supply and RGBW strip
- App-based control with no additional gateway
- Scenes without a complex DMX control layer
- Retail, bars, restaurants, shopfronts and temporary spaces
PATH 03 · BLUETOOTH TO DALI DT8 RGBW
Keep DALI precision. Commission it through Koolmesh.
HBTD8200D/RGBW and HCD038/BT/RGBW bring wireless grouping, scenes and colour adjustment into DALI RGBW projects, with flexible placement in switch boxes, furniture or suitable service spaces.

A workflow designed to save time
From first device to documented handover.
The project team works through one clear sequence instead of rebuilding every colour and scene independently.

Where RGBW earns its place
Different spaces. Different reasons to specify colour.
The right result is not “more colour”. It is the right white, the right accent and a control method the project team can commission and maintain confidently.
HOTELS & HOSPITALITY
Atmosphere that changes with the guest journey.
Stable warm white for comfort, repeatable morning and evening scenes, and app control without a separate gateway.
