The L13 has two light sensors, from the LD2412S, and a separate BH1750.

On top of the L13, we added an additional light sensor, the BH1750, which is the one used on top of the 2A. We had a chance to compare their performance, the LD2412S saturates the light easily, while the BH1750 has a higher level, which is a slight difference. We accidentally also noticed that the light sensor of the LD2412S has some quite a few improvements compared to the LD2410.
