Here are the specs taken from the Eagletac website:

55 / 12.5 / 4.5 / 1.5 Hours
Brightness Selection Ring
3xCree R2 LED
4xCR123A or 2x18650 Li-ion

This was a $150 light when I bought it approx a year ago. It has not seen much use. But, the light output is VERY nice, and it has quite a lot of throw.
My price is $99I have the original box, carry case, screw on defuser, original carry strap/lanyard and instructions. It also already has the seperate rear clicky switch installed.
Please PM me or email me at: goldfishpanda@hotmail.com if interested. This was my very first "nice" flashlight. It really is awesome. Pics and additional info below:
