By some odd coincidence LSH-P 1551 *is* a Fraen optic version too /ubbthreads/images/graemlins/tongue.gif , another of the first ones. I keep the 2AA pack on it so I easilly know which one is which.
The Arc4 really is tremendous. I think this could be one of the best lights I`ve owned so far, and I have owned rather a lot of lights in my life! My only complaints so far are already going to be addressed in the future - the lack of knurling on the head, and a tail switch guard so I can EDC it wihtout worrying about it activating accidentally. I already dropped it once when it slid out of my grip so I hope the combination of knurling and a flared tail pack will make it easier to hold on to. I got the hang of the settings menus after only 5-10 minutes of fiddling, having played with the stimulators and read the advanced instructions already. Got it set with primary on level 3 and secondary on about 10 or so, that gives me a good range of brightnesses.
I said it before and I`ll say it again - the Arc4 is a masterpiece of mechanical, electronic and software engineering. Could this be the future of flashlights? I hope so.
