A quick update. I purchased a white and red LED tail cap from Mike at PTS. The red one was dead on arrival, but Mike's outstanding service had another in route the same day that I contacted him.
The white tail cap puts out a nice medium sized spot that carries decent throw considering that there is no reflector. There is also moderately bright wide side spill with some rings at the outer limits of the spill. The beam pattern is expectedly not as clean as that of an A2, but the addition of the tail cap does provide much of the same utility.
The red LED tail cap has a spot that is a bit tighter and the side spill is dimmer than the white. It looks a lot like the beam shots from the A2 red LED output.
I am very happy with both of these. Output is decent and while the beams may not be A2 quality, they come at a far cheaper price and help to turn the Wolf-Eyes lights into more of a light system (Mix and match components from lamp assemblies to tail caps to meet your current needs). Please keep in mind that I am using a 9D Raider body and that your results on a different body using less or more cells may be different.
Thanx again to those who replied.
