An incandescent light bulb radiates at a rate of 60.0 W when the temperature of its filament

Question:

An incandescent light bulb radiates at a rate of 60.0 W when the temperature of its filament is 2820 K. During a brownout (temporary drop in line voltage), the power radiated drops to 58.0 W. What is the temperature of the filament? Neglect changes in the filament's length and cross-sectional area due to the temperature change.
