I have few of the KILL LIGHTS< and been very happy with them

you DON"T have to have two lights either, but its both easier and safer as you don;t have to be pointing your gun all over to just LOOK for things
and IMO there is an advantage of having two of the same lights, over two different brands, this way bulbs, battery''s chargers plugs and such all will be the same
or that;s what I do, to make mu life easier, have way too many chargers for things as is LOL
