Selection Notes

XVB7C21B is the 24v-connection base in the Harmony XVB7 line, which sets both its wiring method and how many lens or sound modules it can carry (5 modules (4 lens + 1 sound or 5 lens)). Pick it when the panel's existing cabling or fieldbus matches this connection type; the other XVB7 bases differ only in electrical connection and terminal style, not in how the light modules themselves signal. Direct or tube fixing keeps the mounting open for either a flush panel cut-out or a pole-mounted assembly.
