IP67 rated UV LED light strip for use against barnacles?

An example of UV LED strips here,

The IP67 rating means immersion waterproof. An IP68 rating means permanently proven waterproof.

I have read that UV light kills barnacles before they attach.
I can find IP67 rated UV led strips, but not yet seen IP68, although they likely make them.

It would be an interesting experiment to stick these onto an underwater panel and see what happens.

Maybe they could be attached to an underwater wire and pulled up against the hull and have miniature floats so they push up.
I don't think the adhesive would stay on the hull. So would be used in a slip etc... when boat is not moving.

I did find an IP68 rated UV strip

Not willing to spend a lot but do like to experiment.

Mr. 717. Might work but would it be any more or less trouble and expense than something like this? Not touting the company at all but seems getting the LEDs consistently aligned and in the best position might be very time intensive. Boat Hull Protector | Buy Now

Thinking just having the UV lights in the water might attract and blind most barnacle larvae round the boat, so placement might not be an issue.
Maybe could set up an array of UV light bulbs underwater on the pilings of the slip.

From the article, seems they do swim towards light since after they are UV'd, they can't anymore.

Au and her colleagues exposed barnacle larvae to a dose of UV-B radiation comparable to the level Hong Kong receives on a typical summer afternoon. The larvae were blinded within 60 minutes, and were unable to swim towards light.

The sightless larvae were also unable to latch onto the surface of a glass beaker or settle. In the ocean, this means that they cannot mature into adults, with their characteristic volcano-like shells.

Regarding a UV led strips, not necessarily the ones I linked, some forum poster said he did make his eyes hurt when he looked at them too long. You're not supposed to look directly at UV lights.
Single bulbs spread around might have more intense UV light, so might be the better idea than LED strip lights. If you can buy low volt water immersible UV bulbs.

Only way to know is try it and see what happens.

Here is one likely intense enough to work, designed for fish tank use, IP68 rated.

Imagine 6 of these hung off side of the boat, three to a side, two or three feet down in the water.

Nice idea, but for $8000 dollars, UV lights certainly a lot less.
Seeing mine is 37 foot and 20,000 lbs. And then don't barnacles and fouling attach to the frame of the air dock? Imagine hauling that out of the water all heavy and fouled to try and clean it.
