yeutterg I'd also be curious if you ever had the opportunity to test a low-CCT fluorescent (like 3500K) at full output.
If I understand your question, yes, the exact same tubes at higher output power do not bother me. The spectrum is the same, I measured it for both low and high power with a spectrometer. I have not yet been able to ascertain whether there are differences in the flickering. Just to have an idea, which frequency range are we talking about?
Thanks for sharing your opinion. I hope more research is carried out, however I am not that positive, as most people do not have any problem with lighting or displays.
