I have shocked to discover that in the thread of "T8 upgrade ?", the member that started this thread, incorrectly listed the color temperature available for fluorescents, while called the 5000K color FULL SPECTRUM!!!
(Before the following text, i used an insulting text, and i deleted it following the discomfort that happened because of this)
There is no color temperature called such. 5000K is daylight, like 6500K, but less blue.
5000K, haven't a richer spectra then the other colors, when analysing it with a spectroscope and the spectral output depends on the phosphors type used.
Generally, the only full spectrum lights source available is:
1. The sun (Natural blackbody) and the moon (Reflected sunlight).
2. Incandescent and halogen lamps (Artificial blackbodies).
3. Short arc xenon lamps (Discharge lamps which produce a flat continuous spectrum in the visible light, that is the closest non blackbody emission to the solar spectrum).
