The LED Disco Bulb popular right now. Almost everyone who sees one, love it. Turn any light fixture into a colorful party with this one bulb. You don’t need a mirrored ball, a motor to turn it, or spotlights to shine on the ball. The effect of all those things is built right into the LED Disco Bulb. Of course for the best effect, the darker the room, the better and the lighter the color of walls, the better too.
