Why wouldn't it be 15 watts, the rated power of the lamp?

asked 09/17/19A 15 Watt desk-type fluorescent lamp has an effective resistance of 200 ohms when operating (note: the 15 Watts is only associated with the lamp). It is in series with a ballast that has a resistance of 80 ohms and an inductance of .9H. The lamp and ballast are operated at 120V, 60Hz.
Find the power drawn by the lamp (hint: for R use the sum of both resistances)
