A lot of lights that use 3*AAA can fit a 18650 in an adapter-tube.
If you have one, could you check that?
If yes, you can get 1000Lm out of that thing with a propper driver and an XP-L or XP-L Hi.
As it is, without 18650 and an other driver - just a plain LED swap will boost the light output by some extend, to like 400lm
