Tanga offers the refurbished NightWatcher Robotic LED Security Light with Color Camera, model no. NW700WH, for $74.99 plus $4.99 shipping. That's tied with our expired mention from five days ago and the lowest total price we could find for a refurb by $5. Features include programmable day or night detection, a rotating lamp that follows heat or movement, 3X Passive Infrared sensors with a detection zone of 220°, and SD recorder for video or images. A 1GB SD card is included.
A 90-day warranty applies, but it's not clear who backs it.
