An update to my post from February 4, 2009. From Season 10 episode 16 of Stargate SG-1 “Bad Guys.” The episode originally aired in the U.S. on 5/18/2007. The team becomes trapped in a museum on another planet and must pose as a militant group and take hostages in order to buy time for an escape plan to work.
In the words of Jörg and Bernd at Ex Astris Scientia, “this must be the best selling lamp series of our galaxy!” There are two sphrical Rougier tube lamps in the museum and one carried enough visual weight that it appeared in a promotional image for the episode.
From GateWorld, a promotional image from the episode.
