This small European developer was showing a new $199 color-shifting lamp, with U.S. distribution planned for March.
Holi’s lamp is square and free-standing rather than requiring a light bulb socket, and uses an app that’s capable of matching both the light’s color and strobing effects to the music you’re playing. Up to three lamps can be controlled at once.
Holi’s app lets you separately change the colored lights inside its square frame, including using photographs to provide a simple reference for what the color scheme will be.
You can also use the app to separately specify colors from a color wheel; the Holi lamp’s top, left, and right can glow individually.
