Uh, you can get LED lighting with different temperatures. If you're using blue spectrum lighting it should have adequate foot candles to keep you from getting depressed. Use red spectrum for low light conditions
Actual spectrum matters, almost all have nasty blue spectrum peaks (even ones with 2700K "temperature ").
Also, the nastiest effect is from PWM noise that causes all sorts of biological issues (human biological functions are modulated by pulsed EM waves at cellular level).
I've personally measured over a dozen bulbs and read measurements on over a hundred, so I know this.
The best LED bulbs that almost solve the above issues are still c. $50 a piece .
This changes constantly. I can't now quickly find the mfg I found 2 years ago. It's somewhere in my links...
Look for no PWM (DC dimming), as close to sun's natural radiation spectrum as possible (no peaks, look at the spectrum, not color temperature), high CRI/TLCI/CQS in the ~99 range. Pref. measured by a third party who understands measurements, so don't trust mfg specs.

Temperature is an integral of the spectra.

Which bulbs are those?
