Wow, ultrafire's shxt again
dont ever trust this notorius brand.
99% of its output is over-rated
the torch in the website is Ultrafire C8 MC-E
(with different marking on the torch,but still the same quality, if you
would do a search on yahoo pictures with ultrafire C8, you will see the similarity)
and this thing will NEVER cost $50
even in hongkong it only takes about $35
in mainland, even cheaper.
single-celled MC-E is not suggested
the cell will have a heavy load over 1C(in case it REALLY gives u 900lm)
Runtime is low, less than an hour
and most case, it wont give u a full output
