We define the term ‘light potential’ (LP) as the plant to respond to sudden increases in PAR, either by using it for productive photochemistry or up-regulating photoprotective mechanisms. In effect, LP is the response of photosynthesis to removal of light limitations.
Mechanisms for controlling the light potentials of LEF and NPQ using MultispeQ field data The rapid reversal of NPQamband NPQhighover 10 s of dark indicated that, under our conditions, a large fraction of NPQ is in the form of qE (figure 3b,c), and thus dependent on lumen acidification and subsequent pH-dependent responses.

It is also important to consider that the fraction of light energy dissipated by the NPQ, i.e. ΦNPQ, will also depend on the fraction of PSII in open states , which will also be impacted by ambient and fluctuating light, Tleafand other factors.
Upon 10 s of exposure to 2000 µmol photons m−2s−1increased LEF to generally higher values (LEFhighfigure 2b), indicating that LEFambwas at least partly light-limited under all of the conditions.
