A hallway in the middle of the night. A closet at the back of a coat. A stairwell with no switch within reach. You don't need a hardwired fixture for these moments. You need a small, smart light that turns itself on when you walk past and turns itself off once you've moved through. This 3.1" (8cm) puck does exactly that. The motion sensor activates only in low-light conditions, so the light doesn't trigger during the day and waste a charge.

Stick the magnetic base anywhere using the included adhesive pad. No drilling, no wiring, no tools, and the install takes under a minute. Choose USB rechargeable or AAA battery power depending on what's easier for the spot. Either way, the energy-saving design lasts several months on a single charge or set of batteries under normal motion-mode use. Pick warm white for a softer glow in a bedroom hallway, or cool white for sharper visibility in a closet or pantry. A three-position switch lets you set the light to on, off, or auto.
