Graeme, it is still interesting information that's kinda on-topic.
the bulbs we use are usually "rated" at a certain color temperature, but if you use a CT meter it will say the color is much different. I don't fully understand why we see it as a different CT than the meter does? Must have something to do with the spikes in the spectrum over-powering our eyes maybe...?

Most mid range bulbs have spikes in different spectrums...

That's why they are called "full spectrum". Some are "fuller" than others though. I think most people know that all the colors in the rainbow are in "white" light.
