PJD,
Early summer is what I heard (starts 21 June) I will be replacing my Streamlight Batonlight (hate the thing, giving it away) the X1 will take the Batonlights place. Getting edgy but have spare N cells so I can wait a few weeks.
The Sonic is one interesting light, wonder how well it compares with the Arc AAA? Will probably go with the Arc AAA as it is a standard on the CPF.
Breath deeply, relax...count back from ten...feel the stress flow out of your finger tips...dream of 25 watt Luxeons that run off of one AAA for three hours...ponder a Titanium X1 with a Luxeon 1W.... relax /ubbthreads/images/graemlins/sleepy.gif
