What lamps were fitted in the titanic and could any still be lingering down at the ocean floor intact?

Also does anyone have any info about the electrical systems in the titanic?

Only thing was that some of the chandeliers were still intact.

Did they have vapor tight fixtures or similar that might be still around?

To be honest, I believe most fixtures at that time were steel and from what I have seen not vaportite. But I really never researched it.

One of the pictures shows the power cable running up the wall semi-loosely! It appears they didn't have the wiring integrated into the ceilings or walls?

I wonder if metal conduit was a thing back then.

I don't think any of the lamps or bulbs would still be intact. The massive pressures at that depth would have crushed them.

Correct.  That and sea water would have corroded them. 

None of them survived the trip even halfway down to the ocean floor. The submersibles that brought explorers all the way down to the wreck have titanium sphere about 2” thick. What chance do 1910s non spherical glass less than a mm thick have at such depth the ship sits?

The only thing that lights up that might have a chance of surviving the trip down to where the Titanic sits intact is gas torches and LEDs. (Until the corrosive seawater deals with them.) Anything else would have imploded even arctubes of HID bulbs.

Titanic (and sister ship Olympic) were fitted with about 10,000 lamps ranging from 16 to 100 candlepower (the majority were 16 to 25cp), most of them being Tantalum filament lamps.

The electrical voltage was 100 volts Direct Current

seems like it would be bad if someone came in contact with a loose wire at 100v dc. was it grounded in some way? that is fascinating.
