Mine was the Nitecore TM28. Before this I owned a few LEDLENSER torches (I still have one and its a great little torch, the others I have passed on to my girlfriend, family).
The reason I got the TM28 was I was wanting something with a lot of punch, but at the same time, be able to fit in my jacket pocket (which the TM28 does) and if I'm planning on been out for a while and or I plan on using the 6000 lumens quite a lot, I can still fit a battery storage case containing four spare 18650's in my other pocket to give me extra use. The reason I wanted something with a bit of punch is, me and my girlfriend like to go out walking after dark, along our local river, which is fairly rural and we can see lots of different wildlife after dark, over the other side of the river where the woods and fields are. With the other torches I had, I didn't have enough distance with the beam, to light that area up, which usually resulted in seeing a reflection of the animals eyes, but not enough to identify it.
The TM28 allows me to see this area (and then a hell of a lot more when I put the TM28 on 6000 lumens) with ease, and we have real enjoyment seeing the animals over there, that we would otherwise not be able to see.
