what A-2 configuration meets these criteria?

[Mr. Blue]

as short as possible.
brightness equivalent or near to a Longbow Micra 1x123 with the reflector.
better run time than the micra.

would a CR2/ NG 400/500 be the choice?

 

[Kiessling]

Aleph2 / NG400-500 / LuxIII / FT Tailcap with 15 ohms
IMHO

Bernhard, any idea on the length of that combo?
And, do you think a NG 400 would be as bright as the LB? I understand the 400 runs about 2 hours, the 500, 90 minutes...the LB is about 75 minutes IIRC.

 

[Kiessling]

Mr.Blue ... I do not have a LB to compare, but the NG is very efficient and the McR-20 in the Aleph2 is a very great reflector ... but in the end, you'll have to wait for someone who has both to chime in.

The length is 8,7cm in the off-position.

EDIT: in the pic it uses a Bald Cap ... just pretend the rubber button isn't there /ubbthreads/images/graemlins/smile.gif
