So if a fixture is rated for 75 watts is it also rated for a 75 watt heat lamp? Im guessing it has to be rated for heat lamp use?

If it has a label that says use type A19 or CFL lamps it is not rated for heat lamps.

Wattage is directly proportional to heat, so a 75W heat lamp doesn't get any hotter than a 75W incandescent.

The only thing that makes the difference is like Mac said, the shape of the lamp which might bring hot surfaces closer to parts of the fixture or restrict air-flow.

Are you talking "codewise" ?

Or best practice wise ?

If you are going to use heat lamps, then a high temp fitting
would be a better choice for long life, as compared to a standard
lamp base.

But not sure what code says in this reguard.
