Great light. Not the brightest, but you can't beat the regulated runtime. It's also waterproof, Division II approved for hazardous environments, will run on NiMH batteries, and a fairly nice compact package. If you plan on using it for any specialized uses, there are a number of accessories available, i.e., helmet brackets, traffic direction wands, etc. There is also a xenon drop-in available for $6 that you can change out when you need something with more throw.
A great value.
