Wavelength of blue/red ganzframes?

Hi there,

considering that, according to http://321shift.org/pdf/Blue%20Light%20Facts.pdf, blue light with a wavelength of about 470nm, is especially effective at shifting circadian rhythms, I would like to know what the wavelength of the blue light emitted by the MindPlace red/blue (ruby/sapphire) ganzframes is.

Thanks,
Thomas
