If I read the website correctly, it uses a standard 5mm (T1 3/4) white LED, with a rated lifetime of 10,000 hours.
So the LED is likely overdriven, at least during part of the discharge cycle.
Brightness should be similar to an Arc-AAA or CMG Infinity Ultra.
I do not have this flashlight or any similar flashlight, so I cannot provide a review or a web URL to one. /ubbthreads/images/graemlins/frown.gif
