"Luminous bottles" is an appropriate moniker for those lamps. I have a Venture 600W HIT made in 2002 by Narva G.L.E. in Berlin Lichtenberg -when they still made lamps there- it looks like your bottom lamp. If I remember correctly, the HIT600 was not sold for plant lighting but as a white-light retrofit to 600W HPS lamps (White-Lux family of MH lamps). Its development must have been minimal given that its initial lumen output is 83 lm/W only. They certainly could have done better with the efficient sodium-scandium fill chemistry.
