Ideas to mod my shelf queen - TR-J18

Is there a resistor bridge “trick” you can do with that driver?

Definitely a boost circuit, if it uses 6-12vdc input and outputs 17-18vdc…wow

Is there any way to parallel the emitters?

found these

Only way to be able to go to a direct drive or linear regulated is to somehow cut the traces and/or make the emitter star parallel instead of series, and when you do that, you have to beef up the switch in the tail cap because current levels go WAY up when you do that
