I'm sadly unable to find the original study where I found this. If memory serves me it was from around 2003.
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.
