You need multiple flashlights, not one big flashlight.
If you need a flashlight for home defense, that flashlight should be right where you need it...already mounted on your rifle, not in your truck parked on the street; not sitting in another room, not sitting next to your rifle where it'll take you 15 minutes to mount it.
1000 lumens is excessive to the point of being counterproductive for a defensive light. You want to blind the other guy with a quick flash (and use the splash to identify anything else in the room). You don't want to blind yourself with light reflecting off the walls, furniture, etc., and into your eyes.
My recommendation would be:
- Get a Surefire G2X (or whatever the equivalent is these days) and mount it on your rifle. Should be around $60 not including the mount.
- Get a small EDC flashlight for your pocket. Something like the Fenix LD09 or LD12 is a good option, as long as you're somewhere around 100 to 200 lumens.
- Get a headlamp. When the power goes out for hours or days (yes, happens) having a hands-free light beats trying to hold a flashlight in your teeth while working on things. Personally I have a Fenix HL21, but I think the HL23 is the closest equivalent they currently make.
If you want a dedicated vehicle light, I'd probably add a couple more of the LD09 or LD12's. The Icon Rogue series used to be a really good deal and extremely durable, but I'm not sure if they're still around.
