There are four specifications when it comes to artificial light:
1. Intensity (this is the amount of light you get, the higher the wattage, the brighter the light will be but it also depends on the source because incandescent needs to be higher than compact fluorescent)
2. KTemp (from Kelvin thermodynamic temperature scale unit which, to us, means the actual color of the light with 'daylight' been 5600 and the 'whitest' light -higher gives bluer and lower gives redder light)
3. CRI (Color Rendering Index which measures how similar to sunlight are the colors under an artificial light - 100 is identical to sunlight but anything over 94 is good)
4. Spectral distribution (this is which colors are specifically emitted by the artificial light and in which proportion -think rainbow- unfortunately, consumers don't get this info from the manufacturers although it would be fabulous for us, birdkeepers)
