Type of light = wavelength/frequency/specific portion of the spectrum.
Plants use mostly blues and reds for growth (dependent on plant type). The aquariums tend towards blue light because it moves thru the water better than the reds (if I remember right). Many of the home lights do not produce the right wavelengths to promote plant growth. The full spectrums are getting better but its a buyer beware market out there. K rating is one way to generally measure. Some lighting packages are listing K, CRI, and graphing out what wavelength/frequency their light is producing.
