Thermal physics question?

The filament of a tungsten light bulb is maintained at a temperature of 127°C with 10 watts of electrical power. When only 5 watts of power is supplied, the temperature of the filament drops to 89°C. Determine the temperature of the environment of the filament. Assume all heat loss from the filament is by radiation.
