The Lutron Sunnata PRO companion dimmer adds a matching touch-dimming location to a Sunnata PRO LED+ dimmer (ST-PRO-N). It works only with the ST-PRO-N. It is not compatible with the Sunnata STCL-153M dimmer, which uses the ST-AS accessory switch. Up to four companions can be used with one PRO dimmer, and the main dimmer must be on the load side. A front-accessible service switch makes bulb changes safer. Wallplate sold separately.
