While I think that TK40 video is the best one ever made
, it is definitely overkill and way to big based on his requirements.
Lights in the 3-5" range will probably not do very well for what you are asking. The Novatac and Ra lights are awesome, but they are just not made to light up far away objects. You need a large and long reflector to effectively light up targets that far away. If you don't mind going a bit longer, then you have a ton of options in the 1 x 18650/2 x CR123 range. I alone sell probably 15 different flashlights in that range, and I only carry five brands. My personal favorite in that area is the
Jetbeam Jet-III M. It is super high quality and has probably my favorite interface. When the head is tightened, it is always on high, and then loosened is user defined to any brightness or flashing/strobe setting that you want. It has a decent sized reflector and is awfully bright, so it should work well for you.
If you want something that is even better for far away objects, there is the
Jetbeam RRT-1 Raptor. The head on it might be a bit too big for you though, so there is also the brand new
RRT-2 Raptor. It does not have quite the throw of the RRT-1, but it should still work for your purposes. The
iTP C6R or C6T are also good choices for you if you want a good bit of throw. The iTP lights also come with a holster and are at a really good price.
