I had to go look up the Thorfire and, while it looks OK-ish, something about it looks a little 'cheap' in the pictures. Thrunite on the other hand I know to be a good quality brand as I own a few and have liked them all so far. A few folks here have the T10 and I can't remember anyone having any complaints.For a compact 1xAA with tail switch I'd also have a look at the Eagletac D25A Clicky. If I was forced to keep only one torch, then the D25A Clicky would be it. Do note that there are both Clicky and Mini versions of this light, with the Mini not having a tail switch.
In general, anything flashlight related ending with ...fire is a cheap version/copy of something else. Or Surefire.
Actually, do you mind sharing why you are hesitating between this two lights exactly? What are you looking for?May I introduce you to the Fenix LD12, LD09 and LD11..... That is if you insist on buying an AA one.Fenix have a lot of great AAA lights, too. I haven't even caught up with their newer stuff like the new versions of the E05, for example. My newest and fave one is the Fenix LD02, it's awesome.Another AAA I adore is the Lumintop Tool AAA. As Aloha said, if you don't mind twisties, the Olight i3s is also awesome in terms of run times - 20 lumens for 8 hours, I think. That's about twice the famous Fenix E01.
