Review on 💡 Full Spectrum LED Light Bulb: 6000K Natural Sunlight Bulbs, 9W 60W Equivalent, A19, E26/E27, 3 Pack by Joe Patterson

These are advertised as "high CRI", but the CRI is only 85. If these really have the emission spectum pictured in the product photos you'd expect them to have a much better CRI. I suspect these are really just the same blue or violet phosphor driving a simple yellow-orange phosphor as any cheap LED bulb. A really good full spectrum LED will have multiple colored phosphors driven by a violet or ultraviolet phosphor. Also, the CRI index is somewhat limited as it only covers the first 8 patches of the color swatches used to evaluate CRI. You also want to look for CRI Ra9, which describes the red rendering. The red rendering of these bulbs is a bit off due to the weak red emission. This leads to many metameric effects on red pigments. Some reds look fine, but others take on a more magenta color, even if the samples look close in appearance under real daylight. This can make a huge difference if your walls have a red color. Depending on the pigments used in the wall paint, they may or may not look proper. Human skin tones also look ever so slightly greenish due to the combination of weak red rendering and the peak in the green-yellow wavelengths these have.
