Re: Gave iNova X1 another chance.
A used Peak Eiger (Rebel emitter).
Stainless Steel with checkering, single-AAA body, keychain post.
Level 4. Narrow beam w/ reflector. About four hours of runtime. 13 lumens on one alkie. Able to take a variety of different chemistries in the AAA format. Tough as nails. Since it's S.S., it'll look good as new in a few years of constant carry next to my keys.
Been in the market for both an N-cell, as well as a single-AAA cell Peak light with keychain attachment. When this particular Peak came up, it was a good deal; so I grabbed it. Output is not as impressive as my iTP A3 EOS on high-mode. But for keychain duty, I think I'd prefer a more durable light. (iTP A3 EOS' only weakness.)
