Do consumer LED bulbs with a high color-rendering index (CRI) emit more or less of a fraction of blue light than the common ‘extra warm white’ consumer LEDs - if there is a rule of thumb?
In particular, I am comparing:
a) Philips Master series, e.g. spec sheet master spec PDF
b) Philips CorePro CorePro spec PDF
Philips provides spectrum plots on page 2 in their PDFs. It is easy to see the ‘peak amount’ of light for a specific wavelength, but I find it hard to judge which one of them has a larger fractional area in the undesirable region 450-480nm.
(I am not interested in the actual color rendering quality - just want to minimize the fraction of blue light).
Sneakily, the high color rendering index bulb (Philips Master) changes its color from 2700K to a warmer 2200K when dimmed, but I am most interested in its full-power spectrum; unclear whether the spectrum plots refer to dimmed or undimmed.
Can anyone tell which one emits less blue light - is it likely to hold for other high color rendering index bulbs?
