Ultrafire C2 - Amp/Volt data and Runtime Graph

[Esthan]

Hi

It's late, and I'm too tired to do any descriptions, but I just finished
the Runtime Graph of Ultrafire C2 Cree on a fully charged AW IC 17670 cell
(1600mAh).

I know it's in polish, but numbers are international

Moc wyjsciowa = Output
Czas = Time [hour:minute]

Some Numbers:

Throw - 54,95 (Flashlightreviews.com scale)
Measured at 3,7V from NDN DF1730SB3A Power Supply, current draw = 0,68A

Throw at various voltage

Moc = Output
Napiecie = Voltage

Current draw at various voltage:
3,0V - 0,11A
3,1V - 0,19A
3,2V - 0,22A
3,3V - 0,34A
3,4V - 0,40A
3,5V - 0,53A
3,6V - 0,58A
3,7V - 0,68A
3,8V - 0,77A
3,9V - 0,67A
4,0V - 0,67A
4,1V - 0,68A
4,2V - 0,68A
6,0V - 0,60A
7,4V - 0,56A
8,4V - 0,52A

Hope You like it :]

I'll try to post some graphs and similar data once every two weeks for
other flashlights I'll be getting my hands on :devil:

Nice work! I really like the voltage vs. current listings. I love my C2 and think it's well worth the $22 I paid for it...it's one of the great bargains out there. I do wish it utilized a buck/boost circuit though, instead of buck only...that way it'd be under regulation with the single cell. But, can't complain...it's a well-made light!

Thanks for posting! :goodjob:
