put a fat capacitor on the led side. the strobe will be dampened a lot, and it will become sorta current controlled instead of PWM.
i did that with a similar model and it went up in light output, with the same input, which was logical. it rounds off the PWM putting the led into a more efficent state.
obviously you need a lot of capacitance to dampen a full strobe, but at such low voltages one of the new 5v type ultra capacitors might put it into a more surging than strobing stage.
also a set of 3xni-cd coin cells might pull it off, and would be smaller per farad. with the right surge the strobe could become more like a extended pulsing runtime, than obnoxious beat.
Notes: caps dont last forever, they do have a MTBF (mean time before failure), and there exist caps that have MANY times more cycles before failure.
only other way is to re-do the software that is telling it what to do, replace the chip with a different chip and stuff.
its the same software that is telling it to do the PWM modes as is telling it to "Pulse" for the strobe, the electical actions are basically the same, the on and off times are different, the mosfet cannot be dampened because they will not handle 1/2on states without burning up.
If you were wondering about which chip to tear off and replace with what other chip, then you will have to get an answer from the real E-Es, who can do that.
