BF B60 Flashlight - Battery Required Question.

[sandyh]

I just bought a BF B60 Flashlight, here's what it looks like http://www.ebairsoft.com/images/BF B60 Rail Flash Light activeated tape switch.jpg
It didn't come with any manual/information. If someone could help me out with what type of battery it needs. I tried googling more info about it, but there's not much info that shows up about it.

Thanks.
