G'day,
Im from Australia couple hours north of sydney. Been here a month or so, was looking for lumintop GT reflectors. Modified some maglites, then built a few torches from scratch, one with 86mm reflector CMT 2850 and taskled HBflex, another with reflector out of $20 ebay torch xhp70.2 and fx-30 driver, CXB 3590 with taskled hyperboost, currently working on xhp50.2 with adjustable focus for a handheld spotlight and car driving lights using convoy l6 reflectors and CMT 2890
Some good info here
