I actually cut down a
M@g 2AA reflector and got it to fit into an Arc LS. It gives a beam pattern fairly similar to an NX-05 but without the square, and slightly more well defined hotspot. I like it better than a McFlood but that's because I prefer a tight hotspot for throw.
The beam does have artifacts in it. Perhaps this is due to changing the shape of the plastic reflector slightly with all the cutting and filing I did to it, despite doing this work with kid gloves. It's also due to the fact that it is a smooth reflector. I am looking forward to the new 17mm reflectors to be released by
IMS that will replace the SO17XA. It might drop right into the Arc LS with little or no modification. I know that Chop has been doing quite a few mods putting the SO17XA into the SureFire KL1 head so he might be able to do the same with an Arc LS. However, popping in a reflector is a mod that I'm sure most modders could and would be willing to do.
Here's a few pics of what I call the "Unholy Hybrid" /ubbthreads/images/graemlins/grin.gif
