The Challenge Of The Light Bulb

Koeppel observes: ”Evolutionary biologists believe that human lighting preferences are the result of our trichromatic vision—rare in non-primates—which makes us particularly suited to daylight and perception of primary colors. There’s an anthropological component as well; for 4,000 years, humankind has been banishing darkness with fire. And Edison’s bulb, at its core, is a burning filament that casts a glow of flame. Abandoning incandescent bulbs means abandoning fire as our primary light source for the first time in human history.”
I never thought about it that way, but it certainly makes sense and answers the resistance that is being shown to accepting the newer look in light bulbs. Actually, from a design standpoint, some of the squiggly shapes of the newer energy saving bulbs are really quite interesting. The challenge is balancing a lampshade on some of them. However, there are some manufacturers that are using the odd shapes as a design component.
A chart explains the meaning of color temperature very simply. It states: “Expressed in degrees Kelvin, this is how we measure things like soft white or daylight. A pleasant soft white will have a color temperature of 3000K. White light ranges from 4100K to 6000K, roughly equal to noonday sun. Higher numbers get increasingly bluer”.
