The bulbs started out great. They weren't as bright as advertised, but hey, saving on electricity is great and LEDs have a long life. However, within 4-5 months of their installation in my yard, all 5 of the lights began to dim. By the end of the 5th month, every single one of them was dead. When I opened them up for diagnosis, I found blown almost all of the 3 mini-LEDs inside each light. I assumed water damage. But these are advertised for landscape lighting.
