I bought these to replace the color changing bulb I used in the floor lamp in class. I had a particularly difficult student who decided to make a deal. The lamp was left behind by a former retired teacher, and the brightly colored plastic lampshades melted and crumbled. Enter multicolored lightbulbs. Children love it and add interesting lighting when we turn off the light to DIY. One of the lightbulbs snapped out of its socket, but a little effort brought it back again.
