I have just received the aspheric lens , it gives an odd picture on the wall.
A lot of spill, a dark ring, and an out of focus picture of the diode face in the centre.

There is no real room to change the focus length, but it might still be an improvement in throw overall.
I will try check again when it gets darker. :D

Are you still using the reflector (probably a dumb question but have to be sure)?

Yes, I just removed the front glass and replaced it with the aspheric lens.
The reflector is holding the drop-in pill in place so I can't simply remove it.
I am pretty sure it would cost me a lot of light too.

That's most likely why, reflector + aspheric is a bad combo, are you getting something like this?

^That's from this thread here: DealExtreme Product Forum: Review and Pics of Modded Flashlight

One option is (is it a smooth reflector or orange peel/light texture?) is if it's a really smooth one is to black out the reflector in some way (I would think matte black paint would work fairly well) and you should get a normal die shaped output.

Yes, pretty close.
It seems to me that blackening the reflector would just remove the spill, not improve the centre light cone?

Well, I am actually quite happy with this.
I might get some improvement by grinding a bit off the reflector or bezel ring to adjust focus length.

Order LED Kit
^interesting concept for increasing die luminance and therefore, spot brightness. Instead of the reflector reflecting light forwards, it reflects unusable light directly back to the LED chip.
