Since I dared using that phrase neutral-daylight tint in topic of thread and risked opening a can of worms, I should quote this thread [Review] SST-20 in FW3A is divine! , which has a good discussion on the topic.
It’s a very interesting discussion and includes comments by THE toy keeper and others on “untinted/neutral white light” (above the BBL at 5000k) versus people’s preference for negative DUV (under the BBL, like the magenta tint of 219b sw45k).
