Having owned maglites for many years, I've always appreciated the build quality, but found that the light output on the traditional two and three-cell D torches fades very quickly. However, thanks to the super-bright LED bulb this torch is not only far brighter than the conventional version, the batteries last far, far longer, too. The range of the beam is stunning, as well. When walking the dog, I am able to pick out objects 100-yards away with ease; it's like having a portable searchlight!
I bought the three-cell version as I thought it would be brighter than the two-cell version, but having compared it to a two-cell maglite, with an LED replacement bulb, I can't see any real difference and the two-cell is certainly easier to hang off a belt loop than this monster.
