ditto. More rugged if the light might see dropping and more cold-weather friendly.
The idea of an LE agency using out-right copies of a domestic product is somewhat unsettling.

I have the Solarforce L2, both in 17670 and 18650. They are very nice bodies, and the standard non-crenalated bezel is nice, but the reverse is only ok, not something I would use on duty (I'm a federal LEO). A G2/G3 with a Malkoff M60L would be perfect, for a general purpose light.
It wouldn't surprise me if you could get 6Ps for around $40-45.00 each. Knowing cops, you need the SF warranty.
Personally, I carry a G2Z in a V70 on my weakside, with a Dereelight 1SM-1 run by primaries. On my strongside behind my holster sits a G3 with a Dereelight 3SM Q3 5A run by a pair of 17500s. I also have in my gear bag a Ultrafire WF-500/HO-R5 and a Solarforce L-900M. Both have been very reliable in use. I'm currently piecing together a ROP LE build.
Lithium ions are fine, as long as you educate the user.
