Yeah, if I could only keep one light, it would be my SSC-modded Basic 42. Close to 100 lumens on high, roughly 10 hours of ~20 Lumens on primary, 30 hours of ~8 Lumens on Secondary and a month of about 1 Lumen on low. A nice wide hotspot, very respectable throw for such a small light, dead flat regulation and probably the very most LiIon friendly lights around.
To be honest though, my Jetbeam C-LE is very very nice as well... Slightly brighter on high with a 14500 cell and a slightly brighter spillbeam on any equilavent brightness setting due to the OP reflector. It's a bit less bulky and should have similar runtimes with both on LiIon cells, but the Jetbeam lacks the flat regulation and relies on just PWM for lower levels and of course, has long term reliability issues with LiIon cells.
Still, until my C-LE dies, it's my favorite then it will be back to the modded HDS. And I might try to get a decent heatsink in the C-LE and a Flupic.
