I only use the Lightforce lights. They are the best built ones out there.
Lightforce - Handheld Lights
They have so many benefits over all other lights I have used. They have helped me win calling contests and place in the top 5, 3 other times.
First, they are light weight and easy to handle. Push button on and off switch, which I like a lot. They have rotating reflector housing that turns to flood or spot to focus light or broaden it out. You can change bulbs from 30 W to 100 W.
They have great accesories too. You can buy a battery pack for them with a dimmer switch, which allows getting away from the truck for calling, picking up the animal, etc. Next is the rifle mounting bracket for a scope and a mounting bracket for a shotgun too.
I personally run the 170 Strikers and the Walkabout kit. I have 2 of the 170 lights one for handheld in truck or with battery pack and one on my AR15 223 for night follow up and recover. I have actually shot many coyotes walking out to pick up the downed one, turning one into a double !
I believe in these so much, that I became a dealer for them this past fall. Let me know if you have any questions.....
