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:
“I waited alone, in the company of orchids, roses and violets who—like people waiting beside you, but to whom you are unknown—maintained a silence which their individuality of living things rendered more imposing and in their chilly manner received the heat from an incandescent coal fire, preciously placed behind a crystal glass, in a white marble tub where it dropped, from time to time, its dangerous rubies.”
—Marcel Proust (1871–1922)
“Frankly, I do not like the idea of conversations to define the term “unconditional surrender.” ... The German people can have dinned into their ears what I said in my Christmas Eve speech—in effect, that we have no thought of destroying the German people and that we want them to live through the generations like other European peoples on condition, of course, that they get rid of their present philosophy of conquest.”
—Franklin D. Roosevelt (1882–1945)
“Most souls, ‘tis true, but peep out once an age,
Dull sullen pris’ners in the body’s cage:
Dim lights of life, that burn a length of years,
Useless, unseen, as lamps in sepulchres;”
—Alexander Pope (1688–1744)
