Dear Graeme,
Allow me to ask the $1000 question : how comparable is your OB correction method is to "M1" measurements?

It's not a matter of how little UV an incandescent lamp emits in absolute terms, it's a matter of how much it emits relatively, since spectrometers measure reflectance. i.e. the ratio of UV to blue light output of the lamp is quite sufficient to trigger obvious FWA/OBE fluorescence in typical papers, just not as much as a using a true D50 light source.
