Comparison of a regular yellowish CFL (left) and a 5500k version (right).
The 5500k is much closer to the whiteness of daylight, but compared to all of my other yellow lights, it looks extremely blue. It only looks normal and white when it’s the only light I can immediately see. (I’m glad I didn’t try to get the 6500k version. That would be far too blue in here.)
Maybe I just need to replace all of my bulbs with 5500s to trick me into thinking that winter is sunny and it’s not getting dark at 4:45 PM.
