Just purchased a new Stinger XT but the dang thing is already on its way back to PA for service. I own 2 Strions @ 12,000 CP and they were much brighter than the XT @ 15,000 CP. The batteries were new and I fully charged and depleted and charged again but still got the same results. Does anyone know what the prob could be. If Streamlight can't fix it I'll send it back for another Strion.
