This time I took it to 800, the camera kept recording but the lights did not fair well.

Bro, you still awake? Lol, jk. Do you plan on going higher?

Time to switch to an LED light. :P

Yep, definitely switch to LED, not sure how the batteries would fare unless you wired them up to the light bulb's power supply

Um.. exactly what bodily cavity was that?

54 ATM is the equivalent of 540m under water. That's impressive for a light bulb. Most submarines don't go that far down.

poor light bulb

That interesting the 54 ATM pressure. Cody I assume it air at high pressure but is it another noble gas?

I have a light and camera rig my dad made to handle ~200 atmospheres but I seriously doubt it would fit in that tank. Great for looking at deep water wrecks in the Great Lakes though. Love the experimentation... Neat see how some things hand pressure beyond their design. [ edit. Ok. Read your response in the comments... That's why the glass sphere! Cool] What about a quartz sphere? I might be willing to flip the bill for a small hollow sphere.

200atm wow that's a lot of depth. Pressure increases by 1atm for every 10m underwater so that camera would survive up to 2km depth.

I need something that can handle 90atm, 400C, and have an over all density less than .06g/ml. Sounds impossible but I think glass might be able to do it.

Yikes my typo no 20 not 200. It's an impressive rig but not *that* impressive.

After your recent test I think you are right. I'll inquire around. You don't need it to last long and it has to be pretty small.

Silviu. I have a single tiny sapphire bearing somewhere. :) I got it from my father years ago. As for a hollow sapphire sphere I don't think I could find or afford one :) I did play with corundum synthesis about twenty(?) Years ago. It was fun. A total failure but fun.
