Xtar 18700 Preview UPDATED RUNTIMES

[Askbart]

Anyone had a problem with these cells running hot? WHen powering a cheap T7 Citipower light, they get too hot to handle after 20 minutes on high. They do make the light VERY bright however. WHen using a Ultrafire 3000mah, not so bright but then again, no heat to speak off.

Maybe the UF batteries are much lower as advertised? I wouldn't recommend any *fire brands or whatsoever.
