On display at IMM Cologne, Sparkler is a wall-mounted lamp designed by Niels Bak Rasmussen for oioi. The slender funnel-shaped tube containing the light source sits in a rotating ball, which enables you to direct the light in any direction. The reading light is optimized to give you precisely targeted light for privacy. Swivel the holder 180 degrees and you also have an uplighter. The lamp is turned on and off simply by touching it.The lighting company oioi was founded by Niels Bak Rasmussen in 2004.
