I also keep one of those cheap $8 Home Depot power-failure light in each room and the garage. In the event of a power failure they automatically come on to give you about 15 minutes of light to find your flashlights etc with a minimum of toe breakage. I replace these every 18 months.
They're UL listed and I haven't had a problem or had even one get warm in the 5 years that I've been using them. The only reason that I replace them is the batteries give out.I don't trust those. Being that they're made in China and are always charging, I'd be worried they'd catch fire.
She added that I have a problem with knives also, oh well...
