This option will be a tough one considering the smaller head, multi-emmiters like the D18vn, C2vn, D4Svn W2, and even the XHP50.2 TC500vn because it's such a bargain. Most of the lights mentioned are a different cell formula of course but when it comes to size and versatility, the multi-emmiters give similar or better throw and a lot more lumens. Alot more heat as well LOL
I guess the T27vn70.2 would run cooler and run longer, so a plus there. All the lights you mentioned arent tactical lights so there is another different there. None of those would work on a rifle. Every light is different and fits perfectly for specific reasons and that's the beauty of it. Everything is a trade of of one thing or another. However all the lights you mentioned are amazing hahaha.
