Would you like cave diving as much if the caves were well lit?

The tubes could have some other benefits as well. Cave trash could not be strewn about willy nilly, no more initials carved in the actual cave surface (the acrylic maybe),and the lighted EXIT signs would eliminate the need for laying lines.

We could provide grease pencils and then the janitor could just wipe off the graffiti once a week.

So now for a difficult question. Should the string of fixed lights be coloured (like in Chinese tourist caves)?

And the biggy: WHAT colours should they be?

Naturally, there should be visible red lights as you are going into the cave, and visible green lights on your way out. The red lights should be on the left side of the cave going in, so the boating rule "red, right, returning" would work. The red lights should be triangular in shape, the green ones rectangular, for the color blind.

But of course! Red to port, green to starboard, with correct navigational shapes. HOW could I not have realised! And I lived on a yacht for 4 years once, shame on me.

Of course, that's for a resurgence. It would have to be reversed if it was an inflow cave .

That system might require some training and certification. We may have to back I up with colored lines painted on the floor like they do in large hospitals.

I like the mystery of what may lie ahead and not seeing farther than say a 12W LED keeps that mystery alive and keeps me coming back for more, if I could see the whole cave then it would kill part of the mystery and atmosphere..

Keep it dark! If you want light flooding, detour to open water.

No artificial lighting please. Just give me my 10W HID. I like the way the shadows dance around as I move my light.

We dive cold water flooded mines quite a bit here in the UK. I like to shield my light and enjoy the peace a quiet of the dark.

[seaghost]

no! dark is why I go there!
