Just as Nick said.. Hg doping extends the life of the tube approx. 40 times (5.000 vs 200.000 hours). But the lifetime is not exactly determined, the glass envelope is gradually covered by sputtered metal thus limiting the brightness and making it look bad. Hg doping is not diffucult and is definitely worth of the time spend with it..
