You could put this fixture on a dimming switch.

This allows the light fixture to be adjusted in brightness and light intensity.

So let's say you have a 60 watt bulb and you install a dimmer switch on the circuit. If you dim the light down to 1/3 the intensity of brightness, the light bulb becomes a 20 watt light bulb. At 20watts that bulb is generating way less heat.

So assuming this light fixture you are discussing is light around the bathroom mirror area. If it is background lighting to light up the room to see - keep the setting on low on the dimming switch. But if at the mirror and wanting to see something up close, which requires more intense light,... crank the dimmer switch to a higher level or on full brightness setting. But remember to not keep the light at the higher setting unnecessarily because that will prematurely burnout the bulb and cook the fixture.

If the dimmer switch is on at the highest setting you would also consume much more electricity which would be reflected in your electric power bill.
