- I wasn't aware that women apply makeup by looking directly at
- halogen, or any other, lamps. That would seem to be counterproductive.
- Perhaps you have not observed your wife very carefully?

- As I pointed out recently, most halogen incandescents have hotter
- filaments than most nonhalogen incandescents, and thus produce
- more UV. But the difference in temperature is only a few percent,
- typically, compared to the sun's radiation temperature which is
- double that of either (6000K vs. 3000K); the UV output of the
- lamp is piddling compared to that of the sun.
-
- Anyway, look at the bright side (npi): your wife is guaranteed
- not to get vitamin D deficiency in the winter!
