The research was to see the effect of no light, normal sunlight and UV lights on the viability of microbes. here is the result:

In the rooms that had no light, 12 percent of bacteria remained alive and viable. In the rooms that were exposed to daylight, 6.8 percent of bacteria were viable — almost half that of the dark rooms.
Rooms exposed to UV light had slightly less live bacteria than the rooms exposed to sunlight; 6.1 percent of bacteria in these rooms were still viable 90 days after the start of the experiment.
