Have you seen jtice's graph of the Fenix on energizer L91 Lithium AAs? These batteries smack some regulation into the lights, while shaving weight and uping cold weather performance. While not as cheap as CR123s online, you can get them in bulk at wherehouse type stores for about $1.60 each and the runtime is longer than on CR123s.
Just so you know, I also have a T1 and find that the Fenix is actually a bit brighter and ALOT smaller. Build quality is comprable.
As far as the Amilite goes, it sure is small and from the picts it looks like top of the line machining and finish. I guess the big question is the output. Just understand that if you compare the output of any single primary cell driven light designed to be compact (Amilite T3) to a 2 cell light with a large optic (Inova T3) you are sure to be disappointed, especially considering the claimed runtimes of these two lights are only a half an hour apart.
The only very compact light I know of that can put the scare in the T3 is the HDS line- even the 42 lumen model is about as bright and the 60/85 models are of course brighter. However, these lights can only maintain this level of brightness for 20-30 minutes.
Also note that the compact size of the Amilite with a reflector creates a beam in which much of the light output is going into the spill. The T3 will still throw more light in the center of its beam.
Let me put it this way- even without knowing much about it, the Amilite is likely to be both smaller and brighter than the Fenix, and uses the batteries you like. If these factors are what is most important, go ahead an spring for the Amilite and tell us about it
. That said, the gains over the Fenix are unlikely to be exeedingly dramatic, the Fenix has a good track record, and its half the price.
Neither light is comprable to the Inova T3, so I wouldn't go into this with that expectation- If you need the absolute brightest either spring for an HDS now or wait for the next gen of LED.
Hope you enjoy whatever you decide to go with.
