Vintage Arc Sodium Spectral Lamp DNAS18 USSR NOS Argon tube DNaS-18

Description: Manufactured by the factory SPO "Lighting" (СПО «Светотехника») in the 80s of the USSR A low-pressure discharge lamp of the sodium type DNaS18 has a linear emission spectrum and is used in spectroscopy, refractometry, polarimetry, chemistry, lighting and other fields. The radiation generated by the lamps with a wavelength of 589-589.6 nm is close to the maximum sensitivity of the eye. The lamp is designed for operation from an alternating current main with a frequency of 50 Hz and a rated voltage of 220 V with appropriate ballast equipment. The operating mode of combustion is set 15 minutes after switching on. The burning position of the lamp is vertical with the base down. It is not recommended to operate the lamps at a current differing from the nominal one by + 15%.DNaS18: D - arc; Na - sodium; S - spectral; 18 - rated power, watts. Mains voltage, V - 220 Nominal Values: electric current strength, A - 1.05 power, W - 18 voltage on the lamp, V - 19 brightness, cd / m2 - 100 · 103 Limit values: power, W, no more - 19 voltage on a lamp, V, no more - 22 brightness, cd / m2, not less than - 80 · 103 Average burning time, h - 200 Weight, g, no more - 80 Base type according to GOST 17100-79 - E27 / 27 Overall dimensions, mm, no more: length L - 165 diameter D - 33The DNaS18 lamp is a discharge tube with activated tungsten cathodes sealed at both ends, enclosed in a cylindrical glass flask. The discharge tube is made of quartz glass and is filled with argon and sodium vapor. The outer bulb is made of glass and filled with argon.
