Radiant Power/Wavelength graph Lighting

  1. Jun 2, 2009 #1
    1. The problem statement, all variables and given/known data
    I have two graphs (Radiant Power vs wavelength) and I have to choose which one would be the best for a shop -- the one with the least yellowing. (fluorescent bulbs)

    I wasn't sure how to tell. The emission spectrums are very similar. The continuous spectrums are different, the one has a wider radiant power in the 350-500 wavelength (in nm) and the other has more in the 600-700 wavelength part. They have about the same from 550 to 590 nm.

    3. The attempt at a solution
    I think the one with the greater wavelength from 400 - 600 nm would be the whitest, without a yellowing effect because it has more blue-green-yellow of the spectrum to make white, while the other has more of the end of the spectrum, indicating a more yellowish light.

    Is this the right way to go about choosing the light?

    Any help is highly appreciated, thank you!
