I mean, ask yourselves honestly, given the amazing output of the newer generation of LEDs is all this risk really worth it? Do you really need more than 100-200 lumens OTF for most applications? I don't. Just saying...
Just a FYI, the OP (member # 553, joined in 2002) posted this thread after reading up on the various risks of LiIon technology; he is unsure that given what he has learned, if LiIons are worthwhile for him.
There are lots of threads on CPF about the specific risks and how best to avoid them, I think that this is more of a discussion thread than a 'what-do-I-do?' thread.
