Commercial lighting controls
Avision Lighting specifies lighting controls as part of the installation, not as an add-on quote. The right system is the one the building staff can recall: 0–10V or switched zones for ordinary white light, and DMX where color, effects, and multiple scenes are the point.

What is the difference between DMX and 0–10V?
0–10V is an analog dimming method. A low-voltage signal tells compatible drivers how bright to be, usually as one level for a zone of white fixtures. DMX is a digital protocol that carries hundreds of channels so a controller can set color, intensity, and effects on addressed fixtures independently. They solve different problems and are often both present in the same commercial building.
Using DMX to dim a warehouse is unnecessary complexity. Using 0–10V to run a color facade does not work, because the signal has no channels for red, green, blue, and white. The specification should name the protocol per zone instead of picking one brand for the whole site.
A deeper walk-through of DMX addressing is in the DMX addressing guide. The operational requirement is the same in both cases: after commissioning, a person who was not at the programming meeting must be able to get the intended scene back.
How is DMX addressing used in a building?
Each fixture is given a start address. That address is the first channel the controller will use for it, and the fixture’s mode decides how many channels it consumes. If two fixtures overlap, one of them will do the wrong thing. Universes are added when the channel count exceeds 512 or when the wiring geography makes a split cleaner.
Zones are a design idea layered on top of addresses. A zone might be “party room” or “north facade,” made of several fixtures that share a scene even if their addresses differ. Writing the address schedule down is part of commissioning. Avision’s published projects do not yet include a sample address schedule.
Who operates the system after installation?
Facility staff, not a programmer, operate it. Wall stations, labeled presets, and a short handover are part of the scope of a commercial control system. A console left in a manager’s office with unlabeled cues is not a finished installation.
