Product details:

The E-Series Transformer allows you to hard wire and dim your LEDs from a compatible wall switch. (We suggest Lutron Diva: DVCL-153P or Lutron Diva: DVLV-600P, please see photos above with full compatible dimmer list) This will require cable to run from the dimmable transformer to the first light(s) - Can use Inspired LED interconnect cables or in wall cables to wire nut into the transformer. Cables are not included with transformer and must be purchased separately.
