- Definition the photon or energy flux onto unit surface area Reference "Napier University. Faculty of Health, Life & Social Sciences. The Environment: LS32209. Light http://www.lifesciences.napier.ac.uk/teaching/env/En9light06.htm [16.3.2011]"
- Comment The units of irradiance are either W m-2 or µE m-2 s-1. Irradiance is measured with a photometer that has a known surface area. It is given the symbol E, not to be confused with the abreviation of 'Einstein'.
