My UniqueFire S7, similarly equipped as the J18, is not making the best use of the emitters’ potential. My driver-modded three-emitter Skyray King with the original old T6 emitters was brighter than my seven-emitter S7. This is a properly driven light with updated emitters; it should easily overpower your J18.
It won’t have a separate mode selection button, but you might like the driver operation better than a click-through.
