Specification answer
Tunable white is a luminaire and controls decision.
Arc, Eco, Flexi, Napoleon and Twist each list a tunable-white plus DALI option in current product material. That establishes a defensible product shortlist, but the final operating range, compatible driver, DALI device type, control interfaces and scene strategy still need project confirmation.
The DALI Alliance describes colour control through the DALI Part 209 device type, including colour-temperature control. Coordinate luminaires, controls, commissioning and user operation as one system rather than separate packages.

Range confirmation
No colour-temperature endpoints are assumed here; confirm the required range against the current selected configuration.

Five verified tunable-white downlight routes.
The shared DALI colour-control option does not make the families interchangeable; output, form and option sets still differ.
| Family | Output position | Ceiling role | Tunable control evidence | Other project choices |
|---|---|---|---|---|
| Arc | 525–2100 lm | Compact to general recessed | Tunable white + DALI option | Beam, Casambi and emergency options |
| Eco | 1000–4550 lm | Fixed round recessed | Tunable white + DALI option | Casambi and emergency options |
| Flexi | 1000–4550 lm | General and higher-output recessed | Tunable white + DALI option | High-CRI, Casambi and emergency options |
| Napoleon | Up to 5300 lm | Low-profile recessed | Tunable white + DALI option | IP54, IP65 and high-CRI options |
| Twist | 975–2650 lm | General recessed | Tunable white + DALI option | Casambi and emergency options |
Controls brief
Define the operating scene before the product code.
The controls narrative should describe who changes the light, when it changes and what happens after commissioning.
Set the range
State the required colour-temperature endpoints and review them against the selected luminaire configuration.
Map the controls
Define DALI groups, scenes, interfaces, sensors and any connection to the wider building controls.
Plan commissioning
Assign addressing, scene setup, handover records and user training before the controls package is placed.
Frequently asked questions
Tunable white downlight questions.
These answers identify the verified family-level option; the final system still needs project-specific controls confirmation.
What is a tunable white downlight?
It is a downlight whose white-light colour temperature can be adjusted within a defined range using compatible light engines, drivers and controls.
Does tunable white automatically include dimming?
The listed product route combines tunable white with DALI control. The required dimming behaviour, colour range and scenes should still be stated in the controls brief.
Which family suits a shallow ceiling void?
Napoleon is the low-profile route in this shortlist. Confirm its dimensions, output and tunable configuration against the ceiling detail.
Is tunable white the same as choosing 3000 K or 4000 K?
No. Those are fixed colour-temperature choices in the current model tables. Tunable white changes colour temperature through compatible control gear, and its actual range must be confirmed for the selected configuration.
What needs to be agreed with the controls specialist?
Set the required colour-temperature range, dimming behaviour and scenes, then confirm the controller, DALI topology, addressing, commissioning and handover responsibilities.
Does a DALI option prove tunable-white operation?
No. Standard DALI dimming and tunable-white control are different requirements. The five families shown here are included because their current option data explicitly states tunable white plus DALI.
