Q: 10. Will this mimic daylight in its spectral response?

A: While the spectral response is not listed, natural daylight would have a CIE Rₐ value of 100, which would be the highest possible CRI rating available. According to Kaiser, the Kaiser KR 90 Ring Light has a CRI value of 94. Typically, a CRI value of 90 or higher would be considered good performance, so the Kaiser KR 90 Ring Light with a CRI of 94 and a daylight balance of 5500K should work for your planned usage needs.
