Figure 1. Feasibility boundaries for achieving 250 m-EDI at the eye within IES RP-1 illuminance levels (300–500 lx). The curves define the minimum combinations of Ev/Eh and m-DER at 300 lx and 500 lx, while the horizontal line indicates a practical upper limit for Ev/Eh. The feasible region lies between these boundaries.
