NEON plasma tube 14.5 x 3.8 cm vintage gas-discharge light bulb for DIY

Beauty and strong shining near Tesla coil or plasma ball! Just look at the photos! They are real! Based on spectral tube LT-2, just without base:) Actually here is scheme on the last photo where says power source voltage 500V 100W. Resistor R1=15kOm 15W, R2=0..20kOm 15W (variable). If connect by datasheet for measure spectre  of light radiation. If for fun or for installation beauty DIY - better use Tesla coil, even so simple and small as on photos.  Datasheet parameters: Spectral lamp of glow discharge with a hollow cathode LT-2 Ignition voltage: 450V max. Discharge voltage: 250V max. The analytical line: depends on element Discharge current: 15 mA Element: Random(Ti, W, Cr, Pb, Ag, Si...etc) Spectral lamp of glow discharge with a hollow cathode LT-2 is intended for use as a radiation source spectra of various chemical elements in the equipment of nuclear resonance spectrophotometry, operating in continuous and pulse modes. NOS, have a signs of long storage, without boxes to make it less weight.
