Wanted to share a quick photo with other popular single cell 123 lights for size comparison. Visually the Kroll tailpack LS appears to be shorter, however my Mofo Clicky equipped EDC'd LS is more compact by a few mm's (it's actually the shortest light pictured).
This light is also modded with a Piglet driving a SSC P4, housed by a copper heatsink behind a cutdown McR reflector. For the fellow modders out there, there's no more worries about increased drive current fouling up Kroll switches.
Looking forward to using this setup at the cottage on Canada Day long weekend!
