These Lights Will Make Les Bleus Look Blue and the Canarinho Look Canary
GE – The lights that GE installed at the stadiums use electric metal halide lamps that emit light very close to the near-perfect white light produced by incandescent light bulbs. But they are much more efficient and durable.
Each fixture holds a reflector with a mirror-like aluminum coating and a special glass lens that trains the light beam on a specific point on the pitch.
“The lamp and the optics are the secret sauce,” lighting engineer Sergio Binda, who works as a marketing director at GE Lighting Latin America, says. “We use special software to achieve the best geometry and increase the intensity of the lamp.”
The lighting team worked closely with scientists at GE Global Research to develop precise and highly efficient flood lights that make colors look natural.
“Light is electromagnetic radiation and each color corresponds to a specific wavelength,” Binda says. “We see colors when those wavelengths bounce off a specific surface, like a jersey. But if your light source does not generate, say, a true red wavelength, then it can’t bounce off and you won’t see that color on the jersey.” more> http://tinyurl.com/mbchase
