Not at all- consider two ways to heat that chunk of lead: a blowtorch in
the open air, or a small heating element under a thick layer of
insulation. The equilibrium temperature is the same, but the heat
fluxes are vastly different.

Hmmm, that's kinda sparse. However, if you have both a high
reflectivity and a low emmissivity, the *net* heat fluxes can be hard to
determine, swamped by the strong sunlight. It sounds like an instrument
calibration problem to me...
