5 hour run time + on low, penetrating light on hi, rechargeable has already saved a bunch of batteries but keep some handy just in case.
Update 4/11/2017
I have used this light daily since August 2015. I climb around in a manufacturing plant working on equipment in all environments, wet, dry, hot and/or cold and more. I can't count how many times I have head butted a steel beam or the like with this light taking the brunt of the hit and it keeps on going. The battery hasn't lost much at all of it's potential, still going 4 to 6 hours. I thought the internal charge port would be an inconvenience, and it is a little, but well worth the 30 second time investment to keep the port clean. I work in a very high dust and or moisture environment and the port is almost as clean today as it was when new.
To sum up, this light is tough and highly functional. Well worth the money.

I just bought another of these as the last one was knocked off my head and fell 20 feet to a concrete floor and broke the hinge, but it still works as a flashlight. That light proved to be very tough in my environment which is why I bought another. Three and as half years off brutal torcher and the battery still worked well as did the rest of it. This will be the only headlight I buy unless Streamlight finds a way to make it better.
