I received my lamps from Walt, Thanks Walt!
I haven't spent too long with them yet, but I tried the 2 cell and 6 cell bulbs, both in "C" Mag-Lites.
I couldn't do a side to side bulb comparison since I had only one light each. My impression was they where brighter by at least some. There may have been three limiting factors: 1) cold batteries 2) batteries 6 months old 3) "C" cell didn't have quite the available amperage of a "D" cell would.
One interesting thing was on the 6 cell light, I could clearly see the spriral filament outline in "light" superimposed over the round beam.
I was able to get a tighter focus with the Carley bulbs, and they do get a bit warmer.
Hmmm, I was ready to be WOW'ed by them, but wasn't. Maybe I need a new "D" Mag-Lite to try them.
