Bests & Worsts Reviews from Amazon

Recommendation to purchasers: test these before trusting them. I've had several cases in which the lights would work as night lights but not as emergency lights. When you first get them, plug them in for 24 hours. Then remove them from the power source. If they light up, you're good. If they don't, try pushing the side button that toggles between bright wide light, low wide light, flashlight, and off. If it still doesn't work, return it. That said, I did buy a bunch of them so maybe one out of ten won't work. Update: more going back. Two out of the last batch fail when unplugged. One doesn't light at all (useless in a power failure, obviously) while the second comes on but lights both as flashlight and main light, and refuses to turn off at all. I can imagine it would be fine if that's all you had, but it sure doesn't work as advertised. Downgrade in rating. These are emergency lights that provide a diffuse light at night, and one or two will replace four or five smaller emergency lights. Also, they take up only one outlet instead of separate nightlights and emergency lights. The downside is that they are bulky and do provide light over a wide area rather than a focused spot. The upside is that they might replace several spot units with just one or two units. Over time, these lights start to fail by flashing constantly. Unless you're running a disco, it is very distracting. They do come on when there is no power, but until that time, one by one they start flashing at night. Another update: I suspect the company is simply repackaging lights that were returned for failing to work properly, since the failure rate is even higher now. If I could, I'd give it zero stars.
