Colored Neons

Electrospell offers a set of four colored miniature neon lamps. These neon lamps have phosphor coatings on the inside walls of their glass envelope. The lamps are filled with a mixture of argon and neon gases at low pressure. These lamps are operated with 120 V or 240 V mains electric power with a suitable resistance in series. Electrical discharge in the argon/neon gas mixture generates UV and visible lights that are further wavelength-converted by the phosphor coating to result in the emission of specific visible colors. The four lamps emit light of green, orange-red, violet and pale blue colors. These are supplied as a set with matching series resistors. Colored neons can replace ordinary lamps in mains indicators etc. The picture below shows details of the spectrum of light emitted by each of the four miniature neon lamps.
