They are likely to be independent. Temperature will be a result of power divided
by energy dissipation rate. The latter will depend on a light sources geometry,
materials and the ambient conditions.

Or to put it another way, different power rating bulbs will have different
temperatures at a given power input, and you can expect manufacturing variation
in power rating.
