I put a PT Impact head on a Tec20 body and powered it up with 2 3.6V AA SAFT cells. Performance of the Impact...size of the Tec20. I think PT's "interchangeability" is pretty neat!
Really? They fit? I keep looking at the Impact II because of the shape and color, but always pass it by because $25 is just too damn much for what it is. If it could also be incandescent or 3 LED, though...
