I ordered a 250lm micro light too. The MTE was so impressive, I got a micro that runs on either a 3v lithium (like you get int the store) or you can pppppput a rechargeable CR123 or RCR123 stubby battery running 3.7v for a little extra UMPH!
I got it with a
pr of the RCR's. It's already shipped, so I'll expect to get it by the next vernal equinox.
