On a similar note, it would be nice if some of the drawers of the fridge had red LED lights to keep leafy greens photosynthesizing, to keep them green.
Not sure how it would increase bacteria, as bacteria don't photosynthesis light, unless the lights gave off sufficient heat to increase their activity. If anything I would think the light might inhibit bacterial growth.
Turn one LED on, while the other stays off.
Observe the leaves of lettuce after a week.
