I was just looking at bright guy and seen these. there advertised to have a redsigned case with easier battery change and water resistance. maybe it was possible for them to do this since there is no switch? im guessing the photon 2000 is the photon1? wouldnt this light be better than the photon 2 if you dont need the switch. I haven't seen anyone talk about it here. im thinking of ordering one since there only 11.50 from brightguy.
