Separate a DALI colour-control label from the actual colour type, driver, light engine and functions required by an exterior scheme.
DALI colour control is a system-selection question. A product described as DALI or DT8 still needs a documented colour type, driver arrangement and compatible light engine. Start with the scenes the building needs, then check that the selected equipment can represent and reproduce those requirements.
A protocol label is not the whole selection
Distinguish the controller's capabilities, the control gear's supported functions and the engine connected to it. A colour temperature control task differs from coordinate-based colour selection or direct channel control. Availability of one does not establish all the others.
DT8 colour-control definitions include different colour types. RGBWAF describes control of up to six channels; it must not be read as proof of seven independent RGBWCLA channels. A seven-emitter Modaluce engine needs its own documented compatible control implementation.
Record the actual interface
Ask for the exact fitting, engine, driver, firmware or relevant revision, supported colour type and controller/gateway implementation. If a gateway is involved, establish which commands and states it translates. A gateway icon on a drawing does not prove every scene, dimming function or feedback path survives the translation.
Keep electrical supply and LED drive requirements separate from the control interface. DALI compatibility does not make drivers electrically interchangeable.
A useful compatibility review
Consider a hypothetical brief requiring normal-night white and several approved colours. List each required operation: select the normal scene, recall an event, adjust an authorised level and restore normal operation. For each, record documented support, the proposed configuration and the check still required.
Where support is unconfirmed, leave the function open. Do not quietly replace a seven-channel requirement with a different engine, or claim that a controller's colour picker proves the installed result.
Commission the functions the owner will use
Include operating scenes, authority, power-cycle behaviour and recovery in the acceptance plan. Record what was tested, who witnessed it and what remains unresolved. Keep credentials and private network details outside public records.
Use the controls commissioning Excel workbook and its PDF companion to record required and observed states for the selected control system. Use the general commissioning record for DALI functions; the Patch planner checks DMX addresses and does not validate DALI addressing. Keep required functions and unverified behaviour visible rather than recording an assumed approval.
Confirm the configuration with Modaluce
The controls guide explains the broader protocol choices. Use Modaluce's catalogue to identify the actual fitting and discuss the engine/interface combination. This explanation describes selection questions, not a claim that every Modaluce fitting offers DALI colour control.
