The CMYK bulb by Dennis Parren combines a white main light source with coloured LEDs in red, green and blue to cast shadows in cyan, magenta and yellow.

The design is a commercial development of the one-off CMYK lamps that Parren developed as part of his graduation project at Design Academy Eindhoven in 2011.

"It is easier to produce and you find yourself more in [the] mainstream of lighting," says Parren of the new design. "That makes it many times more accessible." He expects the bulb to be priced around €95 when it appears in shops.

The prototype was showcased at Spazio Rossana Orlandi in Milan this month, together with a shade Parren developed especially to complement the bulb.

The faceted Diamond shade is made of matt white polypropylene covered in tiny pin-pricks to scatter coloured dots of light onto surrounding surfaces.

"The shade derived from a previous project, the RGB Galaxy," he says. "I chose this shape because the light sparkles through the little holes like a real diamond."

Other lighting on show at Spazio Rossana Orlandi included a wind-up folding lamp by Nika Zupanc.

    Great and simple idea, but I’m confused about why it’s called the CMYK bulb. Especially the K part, or is that when the light is switched off?

      Isn’t the CMYK reference about the shadows it casts? I’m sure you’ve seen a black shadow before ;)

    Exactly our comments, first rule of light theory, RGB.

  • Lolo

    Is it possible to design the bulb cheaper than 95 quid? BTW, agree with the previous comments.

    • Possibly, once the production follows the usual innovation curve.

      This looks like a wonderful product :)

    It’s really nice. But 95 quid?!
