Wattage is what matters.  (P=I*E or Watts=Amps*Volts)

 975mA @ 5V   = 4.875 W
1060mA @ 3.3V = 3.498 W (less, not more than the first)
2360mA @ 5V   = 11.8  W (a lot)

Note that the worst of those is less than

12.5W and 18W.  Still not as bad as a light bulb.

http://micro.magnet.fsu.edu/electromag/electricity/resistance.html seems to
cover this topic nicely, including stuff I've thoroughly forgotten like the
resistor color code.
