Abstract
It is the purpose of the present paper to draw attention to some of the special characteristics of high-voltage fluorescent tubes, with particular reference to the cold cathode type available in this country at the present time. Before dealing with the tubes themselves, the various types of cathodes used in high-voltage fluorescent tubes are discussed. This is followed by a brief account of the more important luminescent materials in common use for these tubes. The limitations of mercury-filled fluorescent tubes for producing very warm light and the advantages of neon fluorescent tubes for this purpose are discussed. Reference is made to the special features of high-voltage, hot-cathode fluorescent tubes
