Figure 4 a shows the current voltage trace for a typical device under one sun equivalent of illumination with an overall power conversion efficiency (PCE) of 0.94 %.
This is also equivalent to the illumination that would exist on a surface all points of which are one metre from a point source of one international candle (candela).
A system in which all RCs in the darkness adapted state are equivalent, and under illumination, this system can be found with certain probabilities in state 2, state 3 or state 4, and shift between them.

This photon density was equivalent to an illumination level of 4, 7.5, and 24.5 photopic lux for violet, blue and green light exposure, respectively.
Thus, the mean visual acuity of great cormorants for targets with high (82%) contrast at an illumination equivalent to that of twilight (1.4 lux) equalled 11.8±0.8 [SEM] minutes of arc.
People in their eighth and ninth decades retain only 10% of a 10-year-old's circadian photoreception, so they need 10 times more light for equivalent circadian photoreception under similar illumination, in agreement with Charman's findings.
Here in New England, where our annual average illumination is equivalent to only about three hours of direct sunlight per day and relatively high electricity rates (about 16 cents per kilowatt hour), either system can replace about 5,000 kilowatt hours of energy a year.
The hyperspectral imaging instrument at IFAC-CNR is a good example of state-of-the-art spectral imaging with illumination geometry equivalent to that of a spectrophotometer [34].
Negative control cells were either kept at room temperature or in a 37°C incubator for a period equivalent to the total illumination time.
