Hey, if anyone happens to know the "Official" color temps of both the red and green lights for COLREGS / Coast Guard, could you post them here? I'd like to do a little research...

Unless I sped-read too fast and missed it, the point of using original USCG approved versus equivalent "un-approved" is solely related to "insurance" coverage. There are a lot of LED and other manufacturers that make replacement bulbs that are functionally equivalent to the original manufacturers bulb. However, since the "USCG certification" is done on the whole unit - fixture and bulb - changing to another bulb invalidates the USCG certification as has be repeatedly said by others.
- - So it boils down to - will the insurance company pay off in an incident directly related to navigation where "lights" are a direct factor? Some companies will, but a the "bargain" insurance companies will probably be very reluctant to pay off if they can cite a violation of USCG certification on a navigation light.
- - Bottom line, if you are not insured you can use anything you want and hopefully something that meets Colreg's and USCG lighting standards. If you are insured you had best stay with the original manufacturers replacement bulbs - - For my tricolor I am looking at $40-60 incandescent bulb whereas other manufacturers sell an equivalent bulb for $10. It's a "gotcha."

For specifications on light colors, Electronic Code of Federal Regulations: will get you started. There is also a small picture of the chromaticity diagram in the February 2010 Practical Sailor. Good luck.

THE ENVELOPE PLEASE:

I would like to take this opportunity to thank each of you for your educating imput. I have come to a conclusion based on what I have read here, and any corrections by the audience is welcomed.

Insofar as I run a power boat, currently with a 90 amp alternator, 3.5kw generator, 90 amp 12 volt alternator, 50 amp battery charger, 2 8D, new AGM batteries and an independent generator start battery my answer, for me is an LED anchor light. Running lights: a bi color steaming nav light, stern light both with incadecent changable bulbs.

Thoughts?

Imho it's not so much whether or not (at least some) LED's are up to the job of providing sufficient light at the correct wavelengths, but that the law hasn't caught up to reality.

Remember when only sealed beam headlights were legal for cars?
I had Cibie' halogen driving lights when they were hard to find (and illegal), and unlike a lot of other driver's aftermarket installations, I first took great care to properly align them.

Finally, the law caught up with the technology and we now can actually SEE at night.
The marine laws will hopefully do the same, as they've done with inflatable life vests.

I have replaced every interior light with LEDs and am very happy with them. I never sail at night but when it is getting dark and the nav lights go on the motor is almost always also on so I don't worry about the power difference. I am using a Davis incandescent anchor light which uses very little juice. I have had to replace it once which meant a trip up the mast. We anchor frequently so this light gets more use than the other nav lights.

The Dr LED brand of lights offers a replacement bicolor light for the Aqua Signal series 25 lights that appears to be well engineered and got good results in the Practical Sailor article mentioned above.

I suppose that if I were cruising offshore at night I would consider LEDs, but for coastal cruising with the engine running they just don't add up for me.

Dr. LED Marine Lighting
The idea of changing out the steaming light does not make any sense to me. You are steaming and that means the engine is on. Why spend the extra money. The anchor light and the running lights OTOH are for times when you don't have a source of amperage (except maybe wind generator power). I like the idea of having LED lights for my tricolor and for the anchoring lights. What I have learned from this discussion is 1) keep your incandescent tri-color as a spare. and 2) LED's may or may not be ready for prime time. I think that I will wait for awhile. Can anyone identify what type of Tricolor this is? Picasa Web Albums - mckenzie.charlie - masthead

I am specifically looking at A14 and A13 tower models to swap out port, stbd, aft and anchor lights on my boat. Any thoughts or concerns or reviews would be appreciated.

So embarrassing, I forgot the link. Thanks Christian
I know this company is in england but post to the USA is cheap by Royal Mail and led's are light. Try this company. www.ecsmith.co.uk

Definitely an Aquasignal tricolor/anchor. It might have a strobe as well.

Excuse me, but have you read the specs?

You wanted USCG approval, you get it (and 4 others, just in case you are very attached to your insurance policy).

Do you know where NZ is ??? Mate, it is down under - Auckland, the city of sails, rings the bell? Russel Coutts, rings the bell?

Have you ever heard of Hella? Their products cost hella've money.

You wanted approvals, quality, bling - you got it.

Now pay for it ;-)))

The regular (incand.) bulbs we use in nav-lights, do they have USCG approvals? I have never seen a statement to this end on the box ...

???
