Originally reviewed this with one star because three days in full sun they did not turn on.  I was issued a refund and while looking for replacements someone mentioned on and off switch under the cover on another item.  I took the cover and light cover off and sure enough, there was an on and off switch.  These work as I originally expected and I changed my review to 5 stars.  I also contacted Wayfair and had them charge my card back for them.  My huge disappointment turned into a great happiness.  Love these lights!
