Motion Detecting Light Bulb
Just like the infomercial says, don’t spend hundreds on high end motion detecting light systems, get the Motion Bulb. Built into the tip of the bulb is a small motion detector. The detector is only active if there isn’t enough ambient light (you can control this) and activates the bulb when it detects ‘temperature changes’. Once you leave its 25 foot-detecting-radius the bulb turns off within 10 seconds to 5 minutes, it just depends on your preference. It’s makers are touting it as energy saving, but at $19 it sure as hell ain’t money saving.
