I think the concern about underwater LEDs and the associated holes isn't about those that require a 1/4" hole, but ones like this

PERKO Inc. - Underwater Lights - LED Thru-Hull Mount Underwater Light

That require a much larger hole.

We just bought a Nordhavn 43 (lucky us!), and we are having some modifications made, including underwater LED's. Right now, I am leaning toward the surface-mount Lumishore lights. We can go with four of the SMX20's, or two of the SMX100's. While the total lumens are about the same, the SMX100 has a 90 degree beam, while the SMX20 has a 60 degree beam. Also, the price for the two larger ones is 2x the price of the 4 smaller ones, net. I'm wondering if anyone has an opinion about the tradeoffs here? The boat beam is 15', and we are adding a 2.5' swim platform extension.

I'm looking at Lumitec SeaBlaze 3 LED lights.

Are the 2 color lights dimmer than single color?

Are these bright enough to project a beam past my swim platform?

Any feedback on these?

Thanks

Anybody install down facing led's while boat is in the water?? We used to install thru hull fittings up to 2.5" with air drills. Is there a sealant that could be used around the wires in the 1/4" hole that would cure wet? Or at least stay sealed? I just put the boat back in the water after a bottom job and didn't think of these until after the fact............

5200 will cure underwater.

Butyl rubber tape would work fine IMO.

We ended up installing 4 of the SXM20's, blue color. These are surface mount with only the wiring coming through the hull. They looked pretty good in Dana Point, and I am sure they will look fabulous in clean, clear water. The fish attraction was instant - as was the opportunistic bird perched on the platform of the boat next to ours!

Confused about colors. Does one color attract fish more than another? Is white better for seeing the underwater gear? Or, is it just preference/asthetics?

The Lumishore rep we talked with recommended the blue lights. Apparently blue penetrates the water the deepest, and is quite attractive to fish. We have seen lights on other boats, and we really liked the aesthetics of the blue light. The white is really harsh, the red is not natural. You can also get programmable ones - but we decided against that, as the cost gets quite high. We got our lights from boatstore.com, with some great pricing.

Yeah I agree with the previous statement pertaining to blue's penetration.

Not sure about fish liking it more tho!

Dr. LED do great underwater lights at a fraction of the cost. Great items and very bright. Worth a look IMO.
