Sorry guys I'm a bit confused and need some help. I recently lost/ misplaced/had stolen my sure fire P2xfury.. I loved that light but it's gone so I figured I'd upgrade. I use the light for hunting and I saw the duel fuel with 1500 lumens and as much as I like the output I prefer the low high mode. So I started looking at other brands and I found the Olight mr2.. but it says drop off after 3 min to lower lumens.. so few questions.. one.. is that permanent meaning every charge you get 3 min burst mode.. or is that runs for 3 min then cools down and you can re burst mode.. two is the sure fire a full time 1500 lumens until the battery is dead.. and three.. can anyone recommend a light with duel settings at a full high output that fits the same size shape and tail cap as the surefire.. I've been researching for two days and I'm dizzy.. thanks in advance I know this is a lot!!
