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.

Famous quotes containing the words incandescent, christmas and/or lights:
“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)
“The fourth day of Christmas,
My true love sent to me
Four colly birds,”
—Unknown. The Twelve Days of Christmas (l. 13–15)
“Thus while I sit and sigh the day
With all his borrow’d lights away,
Till night’s black wings do overtake me,
Thinking on thee, thy beauties then,
As sudden lights do sleepy men,
So they by their bright rays awake me.”
—Sir John Suckling (1609–1642)
