I just received the new build today, it LPM'd in at just under 2.4W :D

I haven't had a chance to put this one to work yet, but upon first impression - the workmanship is first class...

The duty cycle for this build is 2 min on / 1 min off which is amazing for a handheld generating this much power. I'll provide more information once I've had a chance to give it a proper test.
