Question New 12v LED Fixture with Existing Panelized Lighting

Hello, I will be replacing an existing ceiling fixture with a new one but my project has a number of complications.
Old Fixture:
  • 12-volt track-style fixture
  • 12-volt WAC Lighting remote transformer SRT-300M-12V

New Fixture:
Power Source:
  • Lutron Homeworks Interactive (circa 2004) Panelized lighting RPM/Dimmer

  • Confirming that I will be bypassing/removing the existing WAC Lighting transformer...
  • Will this fixture dim without running the extra 2 wires?
  • Will the new fixture work/dim with the existing feed from the panelized lighting?
  • If wires must be run for dimming, then where would they run from?

When I tried to clarify with the manufacturer, I received the following:
  • 24V
  • Dimmable 1-10V (you need 2 wires)
  • The driver inside the canopy is already dimmable: you need only a 1-10V controller
But this doesn't seem to clear up my confusion. 14-2 is already run to the existing transformer and then more 14-2 from the transformer to the existing fixture. Are they saying I need 2 more conductors in addition to the 2 in the ROMEX?

Thanks, Jeremy

You need two additional wires from the fixture to the dimmer location. You can just purchase a 100k ohm variable resistor or a 1-10v lighting controller.

This is one such dimmer.... there are many. This dimmer would be in addition to the on/off switch.
