Came across something on lighting. Artificial Lighting technology paper. When buying lights these are the numbers you should look for:

Kelvin rating of 5000 is considered a "daylight" bulb. Higher ratings take on a "bluish" glow - not bad for plants at all and not bothersome to people.

CRI - natural daylight has a rating of 100. The closer you get to 100, the better the simulation of daylight.

Keep in mind that plants need the red and blue spectrums to grow, but as someone who's been experimenting with this stuff for 3 years now, the blue and red just don't cut it by themselves for us humans. We need more than that to assist in the absorption of calcium, make workers work and children learn more efficiently.
