I'm real happy right now with the advances in white LED technology for flashlights. I have a light that produces 135 lumens and lasts for as long as 2.5 hours. The other, older tactical light that I have will do 125 lumens for only
60 minutes on a more expensive battery. The LED bulb will also last longer and it is more resistant to recoil.Yeah, a bunch of high-dollar batteries going out at once can really suck.
