The new Sunnata companion dimmer switch allows you to expand the use of your existing Sunnata Pro dimmer switch (ST-PRO-N-xx only) and its advanced LED+ dimming technology to create multi location applications. Tap the switch once for your favorite light level, set by your Sunnata dimmer switch, and twice for full brightness. Swipe the light bar to adjust light level. The smooth fade on and fade off allows your eyes to adjust comfortably to your determined light level; push and hold for 30 second delayed fade-to-off. Wallplate sold separately.
