I just got mine on Friday from BRIGHTGUY.
It has it's pluses and minuses over the old model.
It is about an inch longer. It is the bezel that changed.
The LS now has a lot bigger heatsink. It is probably running a bit hotter. It is a little brighter than the old one.
The reflector is only smooth toward the top.
about 60/40 I'd say.
It has a nice tight beam. White also!
The downside is that it does not fit in your pocket as well as the old one. The new bezel size is too big I think.
Other that the bezel being too big, I like it.
