I've had a PH50 out on patrol with me for several months now and although I do try and baby it and keep it in its case it has survived the bumps and bruises that any light in our profession does and I haven't had a hiccup yet.
Heya,
One more question here... is the finish on the PH and the PF the same?
I.e. does the PF-40/50 have the same colour/finish/look as the version with the handle i.e. the PH-40/50? I'm only asking because it looks different from the photos I have seen online... but then photos are photos and lighting could have been a factor in making the lights look different.
