Zebra appears to have 3 different beam patterns for their AA neutral headlamps: H52w with reflector, H52Fw with reflector and diffusion on the lens, and H502w mule (no reflector). Does anyone have beam shots of these to compare? I'm pretty sure I have these lined up most to least throw and most hot spot to smoothest beam. I have several older Zebra's with optics the H51w, which of the three is closest to the H51w?
