I have the 8NX. It's a great light for searching for stuff up to around 100 feet. I am not a LEO, I do production work. But I do have to frequently search for lost equipment or make sure any equipment is not left behind in a dark outdoor/indoor situation, and in my group I have the only light/torch that can see into the rafters of a 30 foot ceiling and to the other end of a dark warehouse from any point in the room. It's just a bit heavy and bulky for me, so I am going to get an E2 or mabey an E2e when it comes out. If you are used to carrying bulky things on your belt like a gun then the 8NX probably won't seem too big.
Other than the size/weight, my only other complaint about the 8NX is that you have to remember to always have a fresh battery in it before you use it for a day. I have left the light sit for a week or so and the battery dies quickly. I guess it looses it's charge when not in use. Other members of this forum could answer the technical reasons for that. But a fresh battery (when properly conditioned) works for around 45-50 min, I will work 18-24 hour days sometimes and I usually wear out before the fresh battery does.
All in all it's a great light and I can't wait until the supposed 200+ lumen lamp comes out!!
One warning about this forum.
It can turn anyone looking for a flashlight/torch into the ultimate light craving madman as it did to myself. I went from a pitifull Mag AA straight to an 8NX and now I want more More MORE light!!!
Hope this helps.
