I have the incandescent model of the Streamlight Scorpion that runs with 2 CR123 batteries. In the interest of saving some money, I purchased a set of rechargeable CR 123s and charger. I charged the batteries, installed them in the flashlight and watched as the bulb blew. Is there a difference in CR 123s? Where and what brand for the best non-re-chargeables? Can I use a re-chargeable? Bulbs are expensive too. Thanks, Dennis
