There's a neat ceiling dome lite repl. LED assembly for $14.99 that has 12 LEDs in a rectangle that would paste right on to the transom for a stern runner.

Auto store also has most all the bulb types in LED at $9.99 and up. Yer lamp assembly looks interesting.I'll hafta investigate doing something similar. Still debating using the work lite LEDs I got as spreader mounted deck lights. Mebbe once I get up the mast to do the masthead/runner?

The Coast Guard approves complete fixtures with bulbs. The do not approve fixtures without bulbs or bulbs without fixtures, nor can they. It is only the combination that must meet standards. What you are suggesting will not meet any standards. Doubtful they will even be visible the correct distance either. And if there was an accident at night you wouldn't have a leg to stand on legally - it would obviously be the fault of the boat with inadequate lights.

Led's are great when used properly. Inside nobody cares what you do but running lights have regulations for a good reason - safety. Best to replace the entire fixture with an approved one or at the very least buy the correct led bulb for any existing fixture from a reputable dealer. The latter still wouldn't be approved but will at least be visible for 2 miles and the correct color.

Re: LED lights

The "RGB" strips are just that. They are interleaved RED, GREEN, and BLUE LEDs are they are intended to be used with a controller that will vary the power to each of the three colors, so you get "disco" or "mood" lighting effects.

For general purpose lighting, that's a waste of time and money. Buy warm or cool white LED strips, and you can buy those way cheaper on eBay as well. Water-resistant and waterproof, check the listings.

No, none of these are voltage regulated. They are all designed to run from a "12" volt supply but they should be fine on "ships power" with the engine running as well. No twelve-volt regulated strip would work well on a battery supply, as even a (relatively) expensive low-voltage-drop regulator would require feeding them from close to 13 volts all the time, so ignoring the regulation issue is a practical way to go here.

I have run them as under-cabinet lighting in a kitchen, and after a year they still look & work fine, fwiw. Powered by a cheap "12" volt brick, with no testing to see what it actually is. I call it disposable lighting: If I have to replace it in five years, at these prices that's OK too. It is NOT anywhere near as bright as fluorescent tubes or other dedicated large bulbs though, it is nightlighting or mood lighting.

Re: LED lights

I decided that the cabin needed lites more than any place else. I stripped the original 5W florescents and added the new twin/12 mini LED-onna-chip strips after the switch. Supplies same or better lumens apparent than originals.
Now to find more/beter LEDs for accent and task lighting, as well as runnig lite bulbs.

Re: LED lights

My neighbour has been using one with a solar panel attached for anchor lights, for about a year. They work well, and are still shining just before dawn.
Looks good.

Re: LED lights

I don't disagree with you. It is easier to get the correct colour temps with incandescent than with flourescent and especially LED.

To get white LEDs to output any sort of meaningful light, you need to mix in some blue, this is why most LED "white" light tends to be bluish

I have used Superbright in a car with no detrimental effects. low power will not kill an LED, but too much will shorten it's life.

I go by my own experience which is that anything over 3000 is too white, I emphasise for my liking.
