It was a broad spectrum tungsten lamp.

Obviously not, why ask a smartass question that you know the answer to? I set the irradiance at the helmet surface to be that of a helmet worn outdoors in sunlight.
Also, do you never come to a stop at any time during a ride?
Again with the smartass question. Like most cyclists, I spend almost no time on a bike ride standing around, so I did not bother to measure the temperature with zero air flow. It's called a bike ride, not a stand around.
The skin of a polar bear [/color]is actually black. The black skin allows them to absorb more UV light to stay warm.
Whoever wrote that has scant knowledge of solar irradiance. At Earth's surface, only a tiny fraction of solar energy is in the UV spectrum.
