It must weigh more than 10lbs if its machined out of a block stainless steel....
I think it stood for Short Rimmed Turbo Head. Could be wrong though.Could someone please enlighten me as to what SRTH stnads for? Surefire R..... Turbo Head?
Thanks for the support guys.
I will look into the possiblity of making a mirror finish reflector to maximize throw, but not sure of the results yet.
If it doesn't work out then it will probably have to go light OP again.
