What I want to do
I was testing two different CFLs looking for differences in their spectra. Since I found that there are different CFLs, some closer to daylight than others.
My attempt and results
I measured spectra of Sylvania Daylight F14T12/D fluorescence tube with
K-Lite FE-GU-14W bulb.
and here are they all together
Questions and next steps
They seem to be clearly different. I am wondering which one should be the best to use for calibration? I think this is something that should be further researched. I found this interesting note by @dhaffnersr suggesting one type of light 23W 2700K soft light works the best.
