notes: label: Description
content: As the 1980s progressed, more companies began marketing compact fluorescent lamps (CFLs). This modular unit was made by Janmar Lighting around 1987. The ballast that controls the electrical arc in the lamp is contained in the base adapter. The globe-shaped cover serves both to diffuse light and to make the lamp less unusual looking. Some consumers dislike the non-traditional shapes of many CFLs and refused to purchase them for that reason.
label: Description
content: It is not known if the Philips tube assembly is original to this piece or if it's a replacement. However it does demonstrate that the new plug-in bases developed with CFLs became standardized within a few years of the technology's 1981 introduction.
