C9 Blue OptiCore LED Christmas Light Bulbs

I'm really pleased with these LED lights - a very deep, bright blue. I like the texture on the bulbs, as compared to the smooth ones. No electrical transformer needed with these, as they work off a standard plug. If something happens to a bulb or the cord, either one can be changed out easily. Can't do that with those permanently attached LED strings.

C9 Blue OptiCore TM LED Christmas Light Bulbs

They look beautiful but they are pricey. These are being used to run down both sides of my drive way and across a path to my front door. They would be running about 7 amps as incandescent but with LED they are less than 1.
