CMYK Bulb By Dennis Parren

Designer Dennis Parren has developed a light bulb that casts colored shadows. The CMYK bulb combines a white main light source with colored LEDs in red, green and blue to cast shadows in cyan, magenta and yellow.

It is the first and only bulb in the world that projects colored shadows. Use it on its own or with one of your existing shades. Works best with open shades.
