Looking for a little advice. I am looking for a very bright flashlight with a tight beam. Something rechargeable and not too large. Maybe something similar to the Surefire 8NX or the Z3. Which of these would produce the more penetrating (tight) beam? I like the Z3 because of the lanyard. This would be very helpful. Can you get a lanyard for the 8NX? Is there another flashlight that would better fit the bill? Thanks in advance for the advise.
