N2 - We studied the bacterial inactivation effects of conventional and decorative light-emitting diode (LED) lamps. We used erythrosine and toluidine blue O as photosensitizers, mixed them with bacteria, painted the mixture on nutrient agar (NA), and then irradiated the NA with commercial green, red, and white LED lamps. The experimental results showed a positive photodynamic inactivation effect on Escherichia coli and Staphylococcus aureus reduction in the experiment. Thus, we demonstrated a decrease in the in vitro growth of E. coli and S. aureus by using easily available LED lamps. This experiment revealed the possibility of using conventional and decorative lighting for daily bacterial inactivation in the future.
