My brother is a student, and is subject to frequent power outages. Last one he used his Attitude (gift from me!) to read for several hours, but I think there are better options. I am thinking some sort of flourescent. It needs to have good output of light for reading and long runtime, and does not need to be very portable. I think Coleman makes some 6 and maybe 8 'D' cell lanterns, can anyone offer me their experience?
