I received mine (above) and just wanted to post a 'thank you'. I have a few XP-G emitter lights or drop-in's from: GoingGear.com P60 D/I, Malkoff M-61, ZebraLight H31 and others but your XP-G drop-in is noticeably brighter and the tint on your R5 is a nice pure white for my eyes compared to many that seem to have a greenish tint to them. Nice heavy hotspot with good spill.
The best comment I can make concerning your 0D0 R5 drop-in is "I'll be buying another one!"
