Wireless Readybright Kit - Whole House

I've been using the Mr. Beams Whole House lighting kit for a couple of years, and it's worked flawlessly for me. The system comes with 3 circular overhead lights (meant to attach to the ceiling like a smoke detector) and three smaller/weaker rectangular path lights. Setup is very simple, and the system just plain works as advertised: when the power goes out the lights around the house go on. Only the remote control unit needs to be plugged into an outlet, so you don't need to use up more than a single electrical outlet to run the system. In my experience, which has mostly been in standby mode, the batteries for each unit have lasted between 1 - 2 years. One nice feature is that if the power goes out and the Mr. Beams lights turn on, but no one is home at the time, the system will turn off the lights to conserve battery power. That happened to us once when we were away on vacation (heard about the outage from a neighbor). My biggest reason for installing this system is that I have 3 young children and especially in the dark northern winter months, we're often in the middle of doing something (cooking, giving the kids a bath, etc.) that would make a sudden power loss a very hectic situation in the first few minutes while we're stumbling for the flashlights and trying to calm/comfort crying children etc. Or worse, someone could trip or get hurt in the dark in a panic. So I have strategically placed these around the house to provide just enough light wherever we are to get to the main backup light sources (lanterns, flashlights, etc.) without any trouble. And it should be a calm and reassuring light for the kids as well.
