This lamp is branded GELCO but I suspect it is made in the Ya Ming/Philips joint venture factory in Shanghai based on its internal construction. Its green color is the result of only using thallium iodide in its halide dose. Also of interest are the redundant ceramic tubes on the arc tube support frame, which are there to prevent sodium loss due to photoelectric ionization in sodium/scandium halide lamps and tri band halide lamps that use iodides of indium (blue), thallium (green) and sodium (yellow) to make a reasonably white light. There is no sodium in this lamp and thus the only purpose these tubes could have is to be spacers to serve as positioning aids for the arc tube mounts during assembly. Note that the getter is a zirconium/aluminum alloy, not magnesium/aluminum as was stated in the video.
