In the movie Frankenstein, I remember seeing tubes in the laboratory.
Besides the monster being scary looking, the tubes and electricity in
the laboratory was also very scary.

There was also two large electric bolts. I think that was real because
I had seen things like that in Edison's photos.

I wonder if these tubes were real or made up to make the movie even more
scary? Also, taking consideration the times: It would be normal to see
electric tubes in a lab.

I wonder if you're referring to Tesla coils.
