Incandescent Christmas Lights
Incandescent light bulbs have been commonly used in Christmas lights until recently. These lights produce a broad-spectrum white light, and are colored by coating the glass envelope with a translucent paint which acts as a color filter. Some early Japanese-made lamps, however, used colored glass. While incandescent light sets are less expensive to purchase than similar LED sets, the operating cost is significantly more. The paint on the incandescent bulbs suffer from fading or flaking when exposed to weather. Older bulbs were also coated on the insides of the bulbs to prevent this effect, but were more costly to manufacture.

“Don’t think of yourself as an intestinal tract and tangle of nerves in the skull, that will not work unless you drink coffee. Think of yourself as incandescent power, illuminated perhaps and forever talked to by God and his messengers.... Think if Tiffany’s made a mosquito, how wonderful we would think it was!”
—Brenda Ueland (1891–1985)
“Adults who still derive childlike pleasure from hanging gifts of a ready-made education on the Christmas tree of a child waiting outside the door to life do not realize how unreceptive they are making the children to everything that constitutes the true surprise of life.”
—Karl Kraus (1874–1936)
“She is watching her country lose its evoked master shape watching
it lose
And gain get back its houses and peoples watching it bring up
Its local lights single homes lamps on barn roofs”
—James Dickey (b. 1923)
