Trio
Lumi
NovaThree specification routes
Choose the colour-temperature method as well as the colour
Trio and the principal Nova model provide multiple colour temperatures from one luminaire. This lets the selected setting be confirmed during commissioning while keeping one product route in the schedule.
Lumi lists separate 3000K and 4000K base models at four output levels, with a tunable-white DALI option where dynamic colour-temperature control is required.
The correct choice depends on more than the Kelvin value. Output, power, aperture or body format, dimming, emergency gear and control protocol all need to remain aligned with the project brief.
Selection sequence
Build a useful downlight schedule
Resolve the physical format and light output before locking the colour and control options.
Set the output
Match lumen package and power to the calculation, ceiling height, spacing and intended light level.
Choose the CCT route
Decide between an on-product selectable setting, a fixed 3000K or 4000K model, or tunable white.
Add controls and emergency
Record phase-cut, DALI, Casambi and emergency requirements against the selected family.

Colour-temperature planning
Decisions to record before commissioning
The selected Kelvin value should be deliberate and repeatable across the project.
Family and format
Confirm the physical downlight family before using colour temperature as the deciding filter.
Output and power
Compare lumen packages within the chosen family against the lighting calculation.
Colour-temperature choice
Choose the target CCT for the space and record it in the schedule rather than leaving it implicit.
Setting responsibility
For switch-selectable models, state who will set and verify the final position during commissioning.
Control protocol
Align phase-cut, DALI, SwitchDIM, DSI or Casambi requirements with the selected family.
Emergency requirement
Add the correct emergency suffix and confirm its interaction with the wider project specification.
Frequently asked questions
Switchable CCT downlight FAQs
Key distinctions between the three current commercial downlight families.
Which ranges are switch-selectable?
Trio provides 3000K, 4000K and 5500K settings. NOVA.001 provides 3000K, 4000K and 5700K settings.
How does Lumi handle colour temperature?
Lumi lists separate 3000K and 4000K base models at each output level and also offers a tunable-white DALI option.
Which family has the highest output?
Lumi extends to 4,800 lumens through LUMI.008. Trio reaches 2,275 lumens and Nova reaches 850 lumens.
Are emergency options available?
Yes. All three families list emergency routes, but the suffixes differ, so use the options shown against the selected family.
Can these downlights use Casambi?
Trio, Lumi and Nova each list a /BTC Casambi-compatible wireless control option.
When is tunable white appropriate?
Use the Lumi /T+DALI route where the project requires controlled adjustment of colour temperature rather than a single commissioned setting.
