I am referring to the SureFire A2.
When the light was first intruduced, it was despised here. Peoole said it was "BOHICA" -- Bend Over Here It Comes Again. Now, it is touted as photonic nirvana.
The A2 has an awful lot going for it. Its aesthetics arguably are not matched by, say, the Kromas. I would say its design is at the pinnacle of incandescent-ness. It is much more than just a flashlight. It is a work of art, in a manner of speaking.
However, A2 has its shortcomings. Its battery life is not long. Its bulb has a finite life (something like 60 hrs probably) and is subject to breakage. When the batteries die, you lose the bright beam relatively quickly.
My Kroma milspec equals or exceeds my A2s' performance in all but fog cutting, throw, and size. The A2's margin is not wide in any of those. The Milspec's high beam gradually diminishes at the end of battery life, a welcome change from my A2s' and my regular Kroma's sudden death behavior.
The reason I would choose an A2 over a Kroma would be aesthetics (owning the lights already). But for performance, the Kroma Milspec is the one I choose.
A very good reason to buy the A2 over a Kroma is cost, ironic since the cost of an A2 was a point of major criticism early on. Maybe people should start saying BOHICA about the Kromas
