When viewed in aggregate some might conclude that I suffer from a flashlight addiction. In point of fact, each serves a distinct purpose including the two new ones which arrived today. One for each of our three cars, one for the shop, one for the master bedroom, one for my office, one that is always in my pocket, one in my toolbox, one for camping, and one more for good measure. All use LED emitters and rechargeable lithium-ion batteries; most can produce well over 1000 lumens, the equivalent of a 75W lightbulb.
