Experience life with Stack lights
Stack intelligently adjusts color temperature to time of day, helping you sleep soundly and wake up alert.
Stack lights have occupancy sensors built right into each bulb, so they turn on and off automatically. Never flip a switch again.
Stack automatically dims and brightens according to the natural light in the room, reducing energy by as much as 40-60%.
Stack lights work out of the box and learn from your inputs over time.
