Toshiba Ends Incandescent Bulb Production After 120 Years

angry tapir writes "Toshiba has stopped production of mass-market incandescent light bulbs, putting an end to a 120-year manufacturing history of the products. The company, which is one of Japan's largest makers of lighting products, had planned to halt production next year but brought up the date by a year. It will now focus on more energy efficient products, including LED (light-emitting diode) lights, which contain a handful of white LEDs and draw a fraction of the power of incandescent bulbs."

so long...

....and thanks for all the friendly warm light.

How about this: the color of the light emitted by CFLs and LEDs is ugly, and sometimes even hard on the eyes (especially with LEDs).

For me, this is reason enough to stick with incandescent bulbs for the places I spend most of my time.

If you consider my above statements to be "crap" then you shouldn't have skipped class on the day they talked about the light spectrum. The spectrum emitted unquestionably differs between lighting technologies.

There's more to light than just color temperature... There's also emitted frequencies. So while an incandescent typically emits light evenly across the visible range, a typical CFL emits light in a more grained spectrum (http://en.wikipedia.org/wiki/Compact_fluorescent_lamp#Spectrum_of_light). So to emit the same "color temperature" and luminosity (brightness of overall effect), a CFL will need to emit more light in certain frequency ranges to compensate for the missing frequencies. And since the human eye doesn't perceive all frequencies equally (We're typically MUCH more sensitive to green than red or blue) it can lead to the light not "feeling" right. The net combination of the colors looks the same, but they are processed differently in the eye which leads to a real, measurable difference. A CFL can never be identical to an incandescent. It's a matter of the physics behind it. Sure, they can "approximate" the light output, but the difference will always be there (and hence why some colors are less discernible under a CFL than under an incandescent)... In situations where color is very important (Artists, designers, etc) an incandescent bulb will be far better than a CFL. In situations (like every day life) where it isn't important to get colors exactly right, then it doesn't matter. But the point is that there is a difference...
