As for you guys on 1418, I think that your best bet is to go with the LM7805 or the old voltage regulators for the radio. I would say that if you guys are stressing about weight to go with the 7805 and get a small, solderable breadboard at RadioShack or off of Amazon. The 7805 would be more work, though. The old radio regulator would probably be the simplest option. You guys could just wire that to the PDP on with a 20A breaker.

Just remember, the voltage drop across each LED must be added as the LEDs are in series. The number of LEDs it can drive will be limited by the source voltage and the maximum voltage the driver can handle.

I've never heard of these before, but they seem really cool!
