Thanks for the info so far. There seems to be a staggering number of lights to choose from. Back in the old days, it was Rayovac or Eveready, & that was about it. The cost is not a critical issue, but I can't buy many lights & try them all myself. I appreciate the comments. I always worry that what seems to be an objective evaluation of a product is really baloney from the mfgr. These days it seems that people will do anything to get your $. <img src="/images/graemlins/shocked.gif" alt="" /> I work in a building that was built in 1905. It has 3 floors above ground & 2 below. There are some pretty scary places down there. I wouldn't want my flashlight to poop out while I was down there & the power went out!.
