A motion sensing outdoor light can be an ideal security deterrent but usually it requires being hardwired into an electric source and thus usually relegated to the side of your house or possibly garage. But this Cordless Motion Activated Light can be placed anywhere because it’s battery powered. The LED lights provide a reliable glare-free wide-angle beam that mounts easily with no wiring required. When motion is sensed the light goes on until there is no motion for 30 seconds. Great for porches, decks, patios, driveways, pool areas, or anywhere else. The batteries will last about 150 hours of operation. $39.95 from Hammacher.
