C9 Red OptiCore LED Christmas Light Bulbs

I bought these lights to replace the peeling C9 incandescent lights that frame my roof. These are bright and the color is very vibrant. Besides the electricity savings, they made the installation easier since I didn't have to worry about breaking them. Plus, they worked perfectly with my existing standard incandescent light strands.

C9 Red OptiCore TM LED Christmas Light Bulbs

Like the bulbs but hate the fact that I can't buy boxes of single color flashers in c7 or c9. Have to buy those from another vendor.

Love these C9 OptiCore bulbs. Not only do they give off a nice, bright light, they are resistant to the weather - have not see any corrosion on any of the 300 bulbs I setup.
