Thanks to Jeremy for the following information: "The 120 Watt size lamp was only made by GEC/OSRAM and was only available in internal-start with a thermal snap-starter. Originally they were only available in clear - see an example on James Hooker's site. The 120 Watt lamp was introduced around 1975 and was the first 'small' H.P.S. lamp (i.e. 'ES' cap-size-lamp) available in the world - long before 70 Watt lamps appeared! Until then the smallest H.P.S. lamp available was 250 Watt!"
