When researching the product I observed Paola from Wayfair responded to a question by "Harriet" on Oct 28th, 2020 asking "Is there an on/off button on the backplate?" Poala said there IS a on/off switch on the back plate so I purchased 4 lights. THERE IS NO ON/OFF SWITCH ON THE BACKPLATE!!! I LOVE these lights, they're beautiful but the information provided about them is INCORRECT!!
