Yes, I'm aware of that JR, being an electrician and electronics buff. Which is why it's especially important to seal those devices from any water. But no matter what there is always a risk factor and I hear you. I included flash in this scenario for the feedback of just this kind of thing. When we take chances to get our pictures, we need to know the possibilities of what can go wrong too. I've never done underwater or flash in the proximity of it but have read of photographers who have. They also found out the hard way, because they lost quite a few flashes in their attempts to pull it off.

In fact I have and do submerge lights, here is what I use

GOOD quality waterproof food storage box, it has been to 20' with these

But I think they found some clear waterproof bags in the end and double bagged it. My preference is the continuous led panel for the project I have in mind. Bubbling dry ice in a clear bowl simulating a caldron of steaming foam. With the clear bowl I can easily place any light under it but still sealed from water. Or small battery colored led inside a small jar or baggie inside the liquid.

Anyway, I'm thinking out loud and trying to plan what I have in my head, and sharing with Hedgehogs and asking for feedback. I know there are waterproof clear bags for photography use, but I haven't found them yet, because at the time I read about someone needing them, I never planned to do anything similar. Now I've gotten older, bolder, and maybe a bit too bored with the norm as to be crazier. But I'm not going to be stupid, if I can help it. Maybe its too late. I'm open to suggestions, ideas, and the hard learned follies others may have tried.

I appreciate your reply JR, both the for the reminder about the high voltage of flash, and the the idea of using a well sealed food storage container. Had no idea it could be used so deep. I may find some of those smaller 160 led panels you linked too for the advantage of fitting into a smaller area. I don't think I'm going to have to submerge any of my equipment directly in liquid for what I'm planning to do, but I still want them protected from splash or spills.

I've heard that some photographers also use vacuum sealed bags to protect equipment from dust or moisture when traveling to areas that need it. This was only for lenses and bodies, but could apply to anything, then resealed when done the job with a heat sealer. Guess it all depends what one needs to do as to what is more applicable for the task. Thought that since we are on this topic, that one was worth passing on too. Interesting how photography is often about problem solving.
