LED spotlights, I think. These are used at the DSV Limiting Factor so far I know.
I found this information recently as I was wondering the same thing, didn’t find anything about the Titan, but according to Wikipedia the Trieste used unmodified “quartz arc lights”.
Amazed no modifications were required!
Thanks for sharing the information. Will keep looking for more.
Naturally they would probably be water cooled.
From what I’ve read about the implosion:
- Sub would have imploded in less than a millisecond.
- The compression would have heated the air inside the sub to 10,000 degrees F. About the same as the surface of the Sun.
- The people inside would have instantly turned into cooked meat jelly that would have then been ejected between the cracks of the hull parts at high speed. Like playdough in a noodle maker.
In short… probably no bodies to recover.
This video from an engineer with experience working with submersibles has an interesting analysis of what was wrong with the design and testing of the Titan: Oceangate Titan: analysis of an insultingly predictable failure
Basically, it was a deathtrap.
Found this video that answers the questions about redundant systems, air, communication, and location. Kinda Click-Bait title though.
All the Best,

He was literally on the sub himself.
I meant it was disregard for human life from a technology point of view.
Most people believe if you can do something, you should.
This belief will wind you six feet under.
Respect technology and adopt what makes sense.
Everything else gets returned to sender to be re-evaluated.
That type of attitude will result in a life frozen by fear.
Travel to the titanic has been done many many times before. They didnt make something and do it because they could, they did something others have done but overlooked risks and did so without a critical eye to safety.
People are killed each year becauee they didnt check the tires on their car, that was their failure, but that doesnt mean nobody should drive
Watch a few Mr Ballen videos. You won’t want to leave the house ever again. And even then, a giant sinkhole might still open up underneath you and swallow you, the house, everything. 
That’s the stoopit part. They got complacent.
There were standards and practices that were ignored to be “innovative”, and they took COTS to a ridiculous extremes.
It’s one thing to go in a homebuilt submarine, say, 50’-100’ down, because you blow the hatch and can swim or at least float to the surface.
Miles down, you hope the sub can make its way back up-top. There ain’t any rescue, and just like scuba-ing down to max depths, you might have hours before you can get topside again unless you want to fizz like a bottle of seltzer, so you’d better make sure everything’s dotted, crossed, etc.
In a sardine-can bolted shut from the outside, it’s life-or-death, and the slightest little thing that can go wrong will kill you dead. Imagine if a Li cell in a remote started fizzing away, filling the cabin with fumes, and getting to the surface was a coupla hours away.
Yeah, no. I’ll just watch the National Geographic special if I want to see the wreck.
That might happen if going to work, or to the store, or for some specific purpose, though. People need their cars for that purpose, and can usually afford to be negligent because they can always call AA if they get a flat or even run off into a ditch. No one thinks that heading out to get muffins will kill them.
Going miles down… that should be your first and only thought.

Complately agree
You could, but when you are a millionaire, you wont impress your friends by telling them i watched titanic on Netflix in my bedroom.
I have a feeling none of them really cared about titanic itself, it is the extreme experience that very few are able to afford and have balls to do, that is the biggest reason why rich people fly to space or go to see titanic, among many other crazy expensive and dangerous things
I can’t even imagine what a pile of 250,000 looks like.
That vessel looked like being made by amateurs. Without knowing nothing about basic safety requirements, that’s enought to stay away from the trip.
Yeah, when I saw close-ups of it, I was all like, “What’s all that shiite hanging offa it?”.
One dewd who was/is an engineer and did some diving stuff critiqued it, and that’s one thing that he pointed out, the potential for entanglement. Get any of those cables hooked on some piece of metal jutting out from the wreckage, and you’re fishhooked there forever.
Can’t quite get out to untangle it, despite what’s shown on “Voyage To The Bottom Of The Sea”. You know, they’re stuck on the seabed without power, and they send out divers to unhook the sentient seaweed that’s grabbing onto The Seaview trying to drownd them all.
This, plus the reward for taking the risk is quite small, like in small peephole. That thing was tiny! I can’t imagine all guests could comfortably enjoy the show.
We have to have people like this and things happen like this. It’s crucial we die. We have to. Some sooner than others. Survival as a species depends on us dying. Overpopulation would do us in for sure. In many different ways.
I thought we were going to cure that in our lifetime. s$%t
