Stream light 2L-X USB dual fuel
"I recently purchased the ProTac 2L-X USB flashlight after using the PolyTac USB for years. Both lights can run off a USB rechargeable battery or 2xCR123 batteries which provides the flexibility to keep the light running if the rechargeable battery runs out. This light could also live in a go bag or war bag with 2xCR123’s installed and be ready to go when needed. The 2L-X is a thinner all aluminum body with presumably better thermal properties than the PolyTac X which has a thicker plastic body. The 2L-X’s beam profile has reasonable throw and spill. I haven’t used it long enough to talk about reliability but all my other Streamlights have performed very reliably with no issues. I would recommend this light as a high performance general purpose flashlight. It is reasonably priced with the USB rechargeable battery and even less expensive if purchased without to use CR123’s. I used some of my LAPG points from prior purchases that sweetened the purchase."
