Understand the driver and LED-load questions behind an outdoor-lighting selection without confusing electrical drive with control protocols.
An LED driver must suit the actual load and installation. Constant current and constant voltage describe different electrical supply arrangements. DMX and DALI describe control interfaces. Selecting a protocol does not settle the electrical question, and matching nominal wattage does not approve a replacement.
Start with the fitting's issued arrangement
For a constant-current load, the intended operating current and the driver's supported output-voltage range are relevant to selection. For a constant-voltage load, the specified supply voltage and the actual load arrangement are central. Neither description grants permission to connect an arbitrary light engine or alter its wiring.
Use the exact Modaluce configuration and issued documents as the starting point. Some equipment integrates the drive arrangement; other configurations use remote equipment. A family photograph does not identify every internal or remote option.
Keep the complete load in view
Record the engine, channel arrangement, operating levels and all relevant electrical limits. For multichannel colour, the connection map and channel loading need their own review. Do not assume each emitter uses the same current or that the engine can be driven from any multi-output device.
Cable arrangement, distance, environment, enclosure and heat conditions can also affect a remote-driver proposal. The responsible electrical designer establishes the arrangement; a general online cable-length rule is not a substitute.
Add control requirements separately
After establishing electrical compatibility, confirm the interface, mode, channel map, dimming behaviour and any required standalone state. A driver that accepts a DMX signal does not automatically deliver the specified startup scene, loss behaviour or camera performance.
For high-frequency LED driving on a compatible Modaluce configuration, confirm the actual frequency and operating conditions for the selected driver and mode. LED-output modulation frequency, DMX update rate and dimming resolution are different quantities.
A replacement review that does not hide gaps
In a hypothetical asset review, the original driver label is unreadable but the fitting identity is known. Record the fitting and available document revision, then obtain the applicable configuration record before selecting a replacement. Do not infer the missing rating from the enclosure size or the previous installation's apparent operation.
Compare electrical output, engine compatibility, controls, enclosure/exposure and the issued replacement method. Record the accepted combination and update the asset information.
Use the technical document review Excel workbook for the editable record, instructions, field guidance and fictional worked examples. The PDF companion provides a printable guide. All worked examples are fictional and are not project records, product-test results or accepted specifications.
Carry the decision into the project
Start with Modaluce fittings and the technical-submittal guide. Electrical installation and testing are qualified work. This guide helps prepare the right selection record; it is not a wiring instruction.
