This is an expensive gadget but if you really want to have it as a night light, you have to spend the $299 on one. The real name is the bitplay Bang! Lamp and works as a desk lamp as well as an unique decorative object.
The fun part starts when you need to turn off the light and that can be done by shooting with the gunin its direction. The lamp turns off this way but you can bring it back to life with another shot.
Features include a size of 47 x 30 x 22.5 cm, pistol-shaped remote supporting a range of 15 meters, and an on-off switch on the power cord. Find it at Dynamism.
