How are photons measured
WebLight, as we see it, consists of billions of tiny packets of energy called photons. Photons, packets of light, emitted from bioluminescent and chemiluminescent reactions are typically measured using a luminometer. Luminometers are simple, relatively inexpensive instruments designed to measure sample light output.
