No. Color temperature tells you how the light looks – not how it signals and affects your biology (circadian impact). Two bulbs with the same color can have very different amounts of the blue wavelengths that signal your body that it’s daytime. What really matters is how much blue light in the 440–495 nanometer range is in the bulb you’re using. That’s the wavelength your biology responds to. It’s not just about warm or cool – it’s about the signals your biology is receiving from the energy wavelength.
