Plain and simple: what does "30 mW m^-2" mean exactly. I was thinking milli watts per meter squared? not sure.

That's exactly what it means; 30 milliWatts per square meter.
That's actually a power density. To get that density, you need to supply the proper number of Watts spread out over the proper area.
For instance, if I put 1 watt into a 6 foot parabolic dish, that would give a power density of approximately 2.62 mW / m^2.
BTW, I am assuming you meant a positive exponent.
