Initial light use efficiency
WebbOne of the most widely used GPP models is the light use efficiency (LUE) model. The core theory of LUE models is that GPP is linearly related to the amount of absorbed photosynthetically active radiation (Monteith, 1972; Yan, Wang, Yu, et … WebbLED efficiency, or efficacy (lumens per watt), has improved considerably in recent years, despite some signs of slowdown in the last few years. LEDs typically available in the residential market have an efficacy of over 100 lumens per watt (lm/W), depending on the model (e.g. directional, non-directional, tubular).
