Photosynthesis evolved under sunlight. We learned previously in our Other Lighting Metrics section that the sun has the approximate characteristics of a black-body radiation source with T = 5900K. For a reference point, direct sunlight at midday has a PPFD of approximately 2000 μmol/s/m². However, the spectra can vary with a large number of factors including geographic location, time of day, season, local landscape and local weather. Above is the spectra of the D65 illuminant which the best approximation of the solar spectra at midday in Western/Northern Europe.

Fluorescent lights have found ubiquitous applications since their commercialization. The linear form factor of the most popular models have enabled them to be fit into grow racks, terrariums and other horticultural setups. There exist many types; however, the general principles are the same. Bulbs coated internally with phosphors are filled with mercury vapor and argon gas. A spike voltage is applied to the gas which causes ionization and subsequent emission of UV light. The UV excites the phosphors which then fluorescence visible light as well as emit heat. The phosphor type dictates the spectrum of the bulb. The spectra are usually very locally peaked corresponding to atomic transitions characteristic of the phosphors.
