Hi Martin,
would you be so kind to explain how you measured your speed light?
I'm interested in that thread as I also really often had the effect
that setting the white balance with a greycard lit by flash led to
high Kelvin values far away of what I expected.
Best regards
Andreas

I don't have the source, as this was one citing several others. But it
seems that compact flashes suffer by aging (the light becoming
brownish) because the frensel lens in front of the xenon tube is
plastic. Mine might be some 6 years old, so I didn't consider it
really "aged", but for not having a better answer (nor what exactly
does cause this aging), I'll have to accept that.
