C9 bulbs

I love the old fashion bulbs. Great price.

Perfect Color!

These lights are the perfect color! I can't wait until it snows. We had similar lights a few years ago and snow made them absolutely stunning.

Looks just like the old C9's!

First of all, i didn't just buy the blue bulbs, i also bought the red, white, green, and orange.. so this review is for all of the above. The bulbs are nice and bright (but not overly bright). I have these on my Christmas tree and they look great! Before i installed them, i had some old vintage C9 bulbs that i had plugged in right beside these for comparison. They look identical. You absolutely can not tell the difference, so if you are going for the full vintage look, look no further. The only cosmetic difference i noticed was the metal base of the bulb, the old one's are made of brass, and the new one's are not. I have been using these for a week now with zero problems. I highly recommend them!

Retro Holiday

The bulbs were a great addition to my Christmas celebration. They were the kind I remember on our home decades ago. I intend to buy the much darker blue (LED) on next year's celebration.
