After receiving my Xeno G42 and marveling at its super deep and beautifully perfect reflector, I thought I might put this question to the forum.
What is the smallest light available with the deepest reflector? (no customs...just retail)
Armytek Predator?
Think smaller.
Romisen RC-G2? It's pretty deep for a 1xAA light...
Nitecore EC1 is very deep. I don’t normally see measurements of such things however.
Tank 703 is very deep for an AAA light. Its also the best AAA thrower.
EC1 eh? I’ll have to look into that. It’s been on my list. I have an EC2.
Keep em comin folks. All these different sugestions could be helpful research for other BLFers.
That Xeno has a really nice and deep reflector 
Here you have another light I know: Keygos KE-67: A Mixed Bag
For smaller lights, I’d say ITP C7 has quite a deep reflector for AA size flashlight. Perfectly defined hotspot. Only a little bit bigger than HD2010 
(about 15-20%)
^ This.
D-Mini VX Ultra with Turbo head.
Pow.
I was just looking at the Incendio and Trust-1 last night. I’ve never had a Lumapower flashlight before.

The trustfire F25 has a narrow but quite deep reflector for its width. Throws well for its size.
Nice well made little light.

Why not just get a bigger light?
Maybe someone can find this in a different vendor / different brand with reflector shots.
A friend of mine has this and it has a very deep reflector (relatively to width).
Edit:
Here you go:

still not a good reflector shot but at least there is one.
ldo1 has deep reflector
How about WIDEST reflector on a AA..??
How about an AA with an aspheric?
Just found a really nice looking light at cnqg.
