PhotonBoy: No, I did not try rechargables. As to why 4.5 Stars? 5 Star lights go "above and beyond" in my subjective opinion. For that the JR would need (in my opinion) Pyrex AR lens, Type III HA anodize, Lockout capable switch, etc, etc. Get my drift? If 5 Stars were easy, everyone would get it and it would be meaningless.
