I saw a listing on Ebay for a Philips HGS203 with two lampholders. I had never seen or heard of there being a two lamp version of the HGS203. At first I thought it was something homemode but it seems to have a genuine Philips nameplate that reads ”HGS203/2x50-80” ”2XHPL 80w” ”3K  ML   Made in France”

Does anyone have any more information about this unicorn of a lantern and are there others like it?
