I am looking for your knowledge and input. I am just a average Joe Doe but I want a good powerful flashlight. I have a 4d Brinkman (krypton I think) that is so-so. I have 2 3D LED Maglites that are better. I have a new 4X123 Cabelas 180 lumen Xenon that is great. That said, the batteries last about an hour and it gets hot as H---! Can I get another type bulb that will fit it that will be just as bright but cooler. I have a couple of coyotes that visit at night that I try to spot but at 4 123's a night it's getting in my pocket. Guess I need to use recharable, huh? I thank you for your help.
