What was the likely interior lighting, if any, for an early 1900's enginehouse, or any relatively large enclosed space? It would seem the "third shift" folks would need a source of workplace lighting pre-electricity. I don't remember seeing any lighting at Como, and it would be dark in there, especially in the winter.
I've decided to try three of the Evan Designs orange self-flickering LEDs hung from the center beam rafter. The effect looks interesting, especially in light (sic) of nothing definite from the prototype. Even a warm LED looks too modern. I'll add plastic "chimneys" around the LEDs.
There have been several pictures taken of the inside of the Como Roundhouse from that era that have shown up either on this forum or in books.These were of the machine shop part.Figuring you need a lot of light to work on a lathe,the lighting should be noticeable in the photograph.
The list of furnishings and equipment in the valuation notes might shed some light ;) on the subject. If it lists, for example, oil lamps that might be evidence that those existed earlier as well. I do not have a copy of the notes, but someone in this group might have them.
