This battery powered, motion sensitive light bar is perfect for those dark parts of the home like cupboards, attics and under the stairs. The light bar provides a hassle way free of getting instant illumination wherever it is installed. With it's compact design, the bar is fixed in place using the supplied adhesive pad - no need for nails or screws. The sensor detects movement and lights up with a total brightness of 50 lumens from its 8 super bright LEDs. No battery power is wasted due to the bar's auto power off which kicks in after 30 seconds. Uses 4xAAA batteries (not supplied).
