I'm creating an emergency kit/bug-out bag to keep in my truck and need to find a good tactical flashlight for it. I'm trying to decide if I should go with rechargeable or conventional batteries. I see that the brightest lights are rechargeable but I'd like to not have to remember to recharge my flashlight every so often. I'm leaning towards being able to keep it with a spare pack of batteries in my bag. I want one that has a minimum 1000 lumens. Anything I've overlooked? What type of light does everyone have? Thoughts and suggestions are appreciated.
