Cow Missing on YouTube just posted a video today which shown various clips of the "test" hallway scene at a different location before it got sent out to the Tower in 1994, which shown various BTS stuff around the outside of the hallway, which shown the original projectors.
I don't know if these were the same projectors which were used when it was transferred to the Tower, but after some research, these are "CRT Projectors" which use three lenses to project the image.
One other thing that was interesting is that the strobes behind the front two wall lights are actually behind the wall, before this I had always thought it was in front of the wall but behind the lamp shade, unless if it changed when it got moved to the actual Tower.
Here is the video if you want to check the rest of it out, but this was pretty interesting how the original setup was:
