Thanks all for the interesting discussion.
I rarely see true darkness and as a result use my lights under a mix of commercial grade outdoor lighting. Until I bought the Malkoff unit, LEDs were worthless under my conditions. The Malkoff was the first LED that I tried that could provide useful illumination and actually punch through the ambient light. Gradually, I became aware that I was sometimes missing details that were not standing out while using the Malkoff.
Recently, I got a good deal on a demo unit SF 8-AX Commander, dropped it into a Maxpedition baton holder and have been carrying it in addition to my 6P Malkoff. Funny thing, indoors my Fenix P1-CE provides all the light I need and outdoors I keep reaching for the SF Commander. The Commander is not quite as bright, to my eyes, as the 6P Malkoff, but the light that it provides is more useful in illuminating the details. The 6P is now mostly a backup light.
As LEDs continue to get better and their full potential is reached, I believe that they will make incans obsolete. Until then, incans still excel in many applications.
Tonight, I worked with a Fire Department truck and medic unit ( 7 people),
two local Police units (three people) and our own patrol unit (1 person). All of them carried incan lights. MagLite, Pelican and Streamlight were the brands in use.
