A quick update: Lanterne 0.5.2 is now on the way up, the only change being that the Strobe window timing parameters are now a "Strobe Period" and a "Duty Cycle". The discussion earlier today about duty cycles just made sense to me, and I think it's ultimately an easier way to manage strobing the LEDs. So, now, you define how long you want each strobe to last, and then the percentage of time during each strobe that the LED will be turned on.

To start with, I'm limiting the maximum duty cycle to 25%. I'm hoping I can find more data somewhere, to better determine the safest duty cycle values...
