Working on a warehouse project, I’ve observed significant different in results while switching b/w two grid types (adaptive grid vs results according to EN 12464-1 & -2) – especially the difference in Minimum lux value calculated across both, which is also reflected in uniformity. I have attached a comparison with a dummy calculation & the huge difference b/w Minimum lux & uniformity can be seen, with same lighting arrangement – by just switching b/w the available grid types.

Why the huge difference among 2 grid types and which one is recommended to be used generally?
