For this reason, they could also be called U-bent fluorescents. Circulaires ou en forme de U c'est un néon "tordu". There are three distinctive types of fluorescent light bulbs. The Nominal Length may not exactly match any measured dimension of the tube. include--(1) lighting. Aperture lamps can produce a concentrated beam of light suitable for edge-lit signs. Though they range in length and width, they all do the same thing: light the room they are in. In the 1990s,[citation needed] various energy-saving tubes were introduced in North America, but unlike the T8 tubes introduced in Europe, the T8s are not retrofits and require new matching ballasts to drive them, while some T12s can use the older ballasts. Trois types de luminophores, émettant chacun dans le bleu, le vert et le rouge, produisent ensemble, par synthèse additive, de la lumière blanche. Designed to run on the existing 125 W (240 V) series ballast but with a different gas fill and operating voltage, the tube operated at only 100 W. Increased efficiency meant that the tube produced only 9% lumen reduction for a 20% power reduction. Compacte : ce sont les lampes à économie d'énergie. U-shaped tubes are FB##T##, with the B meaning "bent". For example, if the last two digits on a lamp say 41, that lamp's color temperature will be 4100 K, which is a common tri-phosphor cool white fluorescent lamp.
