“As lighting manufacturers developed new, more energy-efficient technologies, such as LEDs and fluorescents, suddenly a light bulb was not just a light bulb anymore. But no one told us light-bulb buyers. “People don’t know they should be looking for three thousand degrees Kelvin, or what we call warm light, so instead they come home with four thousand or five thousand degrees Kelvin, which is cool light.” This information is printed on packages, but most people don’t know to look for it.”
