This Tuesday I pulled the trigger on a Jetbeam BA20 and it just arrived this afternoon. I couldn't wait to tear open the package to my first XP-G R5 light. Opened it right up and stuck in some partially used alkalines i had lying around, even with the old alkalines it is brighter than my Surefire G2 KX4. I am pleased with the beam, although not as clean as the Surefire, it is bright and has a nice cool white tint which I like the best. This is my first 2xAA format light and I decided to go with it after learing it was brighter than the Fenix LD20 and the Quarks, and it is about twenty dollars cheaper. Thanks to Selfbuilt's review of this light I am now a proud owner of a 270 lumen BA20. :naughty: I can't wait to test this thing out when it gets dark comparing it my Surefire.
