No specific budget…thinking hand held. But, open to other light suggestions or feeder lights.

For just a spotlight, it is hard to beat Dewalt's 20v. It puts out a great beam and lasts a long time per battery.

We have similar hand held lights made by Milwaukee which take the standard 18v rechargeable batteries all of our Milwaukee tools take. Way more light than any of the other handheld battery powered lights I have- including stream light waypoint and the browning high noon. Literally multiple times better light.
I bet the dewalt above is the same type high powered led as the Milwaukee.

I have an Elusive Wildlife green beam mounted on my AR. I've never taken it out so it's basically brand new.
