The lamps Doug used were provided by John Gaughan, who still owns them today. They are not Houdini's actual lamps, but vintage and still operational. Below is a photo of Houdini in his workshop where you can glimpse his own Conradi Lamps.
So along with the Water Torture Cell, the Vanishing Elephant, and Walking Through a Brick Wall, we can add the Conradi Lamps to the Houdini effects that Doug revived in his television specials.
