    We went out and bought lamps from these four companies and measured their
    spectrums. We published our findings (spectral plots and CRI calculations
    based on spectral sampling of every 10 nm.) at the web page below.

    We were not surprised to find that their CRI claims are far from accurate.
    Buyer beware.

    Please go to http://solux.net/comparison.htm to see the results.
