I ordered the 8" size to hang outside. Most of the colors are great, but the orange and yellow actually have the same color lights -- only the plastic on the balls differ in color. The yellow lights are also dim compared to the other colors. (Wayfair was great in refunding us for the yellow light. ) One other quirk: the cord lengths are inconsistent. The cord for the pink light was about 1/3 the length of the others. Even with those flaws, I would buy these again. They are bright and festive!
