I am using a superbright, and I want to know how far I can push it.

BTW - what beacon are you talking about?!
Either beacon. What I want to know is how to figure out what the limit is when it is being pulsed so I can reach it. Like I said above, the easy solution is to just hook it up to the +battery and ground pins, but I want to start understanding how modulation applies to electronics. The LED is just an example I want to use in this case.
