+1 Cree L1 - Own it and love it. Low is 10 lumens, but because of the optic, this "small" output is QUITE useful. Great throw, but with enough fill light to make sure that the "tunnel vision" of the last model, (which were also great lights) is not a problem at all. The 65 lumens looks as bright as my Fenix L1t- which claims to producee 98 lumens! Also, with the optic, the throw is unbelievable for a light of this small size.
Add the light weight, pocket clip, two stage tailcap, long run time on a single battery, (I think it says 16 hours low, 1.5 hours high,) and you have a close to a perfect light as I can think of, given what you say you are looking for.
I don't own one, but I hear rave reviews of the "backup" as well. My understanding is that it is a less expensive light with the same optic and some type of clicky tailswitch. There are plenty of descriptions from people here who own and understand that light here on CPF.
This will be your first SF- but it probably won't be your last!! Good Luck and Enjoy!!!!
