There have been a number of generations of SF L1,
five in total I believe. Does yours have the short body / short clip like in that review, or is it more like the slightly longer one I have photographed in
my L1 thread here (the higher of the two L1's pictured)? (I think that they both have the same exact lens & square beam profile, just slightly different body shapes.) From what I've read, the body pictured in the link you provided is slightly more desirable than the longer body - longer clip version that I have pictured in my thread.
From what I understand (including conversations with
CPF's #1 L1 upgrader, 'Milky'), that aspheric lens cannot be readily adapted to newer LED's, so the best upgrade (IMO) would be to have him mod the head (newer emitter, driver, reflector, etc). A bit spendy but well-worth it IMO - that's what I'm going to do with that NIP L1 that I have. BTW, in my thread I cited, I have links for two particular SF L1 mods that have been done by 'Milky' - both very very nice.
Otherwise, I guess I might recommend selling it - the L1's seem to have a 'floor' value of ~$80 due to that excellent two-level tailcap, and I think that the oldest bodies may have slightly more value than that when in good condition (i.e. desirable modding hosts).
Hope this helps,
