Artemide Spectral Light Suspension Lamp

"The lamp is composed of 12 wavelengths of light, emitted by 12 LEDs of different semiconductors, corresponding to 12 wavelength peaks perceived by the living species we have chosen: humans, dogs, cats and plants. To avoid unnecessary risks for people with age-related macular degeneration, we do not emit blue-violet wavelengths below 470 nm, because the wavelengths between 415 nm and 455nm (and, especially, at 430 nm) are dangerous to the retina of people with AMD. The wavelengths that therefore make up the lamp are for humans 470 nm (blue), 534 nm (green), 564 nm (amber). For the dog 470nm (blue) and 555nm (yellow). For the cat 500nm (cyan) and 556nm (green), and for plants 470nm (blue) and 662nm (dark red). Then we grouped some of the 12 similar wavelengths between animal and plant species. We then multiplied the number of LEDs of certain lengths proportionally to the intensity of the sunlight spectrum in order to replicate, when all LEDs are on, the quality of natural sunlight. A special "night" program is also proposed. , which maintains only the wavelengths above 550 nm. The convex shape of the top of the globe makes it possible to direct the 12 wavelengths of light that are then transmitted through the clear glass conduits to the opal surface portion of the glass globe to converge lights and colors to be mixed and homogenized to produce the spectrum of natural white sunlight for addition and color synthesis."
