Re: X1--Master Thread Countdown
"Regulated...runs for 10 hours". This could mean that it has a fully regulated run of 10hrs, which would be one of the longest of any commercial LED light. Or it could mean that it runs regulated for Xhrs, limps along for Yhrs and dies at 10hrs. There's no way to know right now.
The X5, which is not that much bigger, has a functional, non-regulated run of about 5-6hrs. Brock's charts indicate remarkably steady output. At three hours it is down only 7% from original brightness, and about 13% at 4hrs (if I recall correctly). And remember that the original X5 (still my preference) was the brightest light of its size before the Luxeons came along. It is still an excellent, viable light.
Since the X1 is one of the largest if not the largest 1AA light I've seen the size/benefit ratio will have to be very favorable for me to consider carrying it. I have never cared for a "laser style" no-peripherals spot beam, but I could see its application to covert operations.
OTOH it looks good and may turn out to be very mod-friendly
At this point, since I EDC "mission specific" lights, I don't see how this light would be useful to me, but I'm keeping an open mind and look forward to reading some reviews in the not too distant future.
