J Williams how much is the diamond reflector. I know about the blue lense I'm gettin one with it.
i e had mixed succes with the diamond reflector. i put in my 21 v belt light and really didnt like it it worked good on the low side by making a nice crisp light that was spread out alot without having to mess with the control knob on the head. but when i put it on the high side the light was to spread out to make a good spot so it was a little weak.. i like a tight spot off the high side so i decided to go with the regular refecor.
on the other hand i put one in my girlfrinends 6v light and it was great. did the same thing on the low side, and on the high side i still held a good spot..
so im gueesin from my experience is that these work better on smaller volt lights.. so yours might work well let me know how it turns out
