These fantastic bulbs slowly change through the colors red, green and blue gradually transitioning through each shade. Their C9 or E17 bases are compatible with C9 cords you may already have on hand.

If you don't have a cord, they can be purchased separately, here.

You can choose to go 100% slow change for your display or mix these bulbs with static pure white bulbs to add a little activity to your design.

The bulbs will change colors independently and not "together" or synchronously.

Great lights

Color Changing LED Bulbs

Excellent purchase for my outdoor Christmas display. Applied them in between triple dripped purple bulbs left over from Halloween. They look great and put out bright, beautiful colors lighting up my pathway. Christmas Light Source Management is FANTASTIC and highly recommend their products and warranty! Merry Christmas everyone.

Great Quality

These bulbs are sweet! The coolest feature is that the bulb is plastic, not glass. So, if you drop a bulb (believe me you will drop a bulb during installation), the bulb will not break. The old school C9 bulbs seemed to shatter at the slightest touch. You will not have that problem with these bulbs. They are extremely durable. They are also very bright and throw off a great shine. The only disappointment is they do not fade in synch. To be fair, there is a warning on the website that states this. I hung 250 of them and most of them seem to fade at the same "randomness". But a few of them are on their own. Red seems to appear significantly less than the other colors. In todays world it seems like it would be very easy to put a box that would let you control the color changes and patterns. Also, I ordered all of my bulbs in the slow change. Upon further research, it appears I should have gone with solid colors for the majority and mixed in some of the slow changes to create "movement".
