A lamp filament radiates energy at a rate of 100 W when the temperature of the surroundings

Question:

A lamp filament radiates energy at a rate of 100 W when the temperature of the surroundings is 20oC, and only 99.5 W when the surroundings are at 30oC. If the temperature of the filament is the same in each case, what is its temperature in Celsius?
