We use Mag-Lites on the job all the time. Generally, the 2 cell AA model is the one in use. However, I feel there must be an alternative that is better... They eat batteries, always have to be shaken to get a brighter light(I hear movement inside, like the batteries are loose), and the bulbs burn out in no time(and are not cheap). Any suggestions for an alternate? I do like the size and metal casing, so who else is out there?
