Thanks Les. I didn't see a need for a 1x123A light so I ordered the L2P instead of the L2M. Commonality/compatibility seems to be what Solarforce is about. Thanks.

BTW the Thrunite TN12 casts a very nice beam. It's narrower than a flood, but it isn't a pencil beam either. Both the medium & high settings (down from Turbo) lit up a good portion of the back yard -- nice. Tomorrow AM at the park I'll get a better idea how it lights up an open area. Lotta light for something you can drop in your pocket.
