That's an exceptionally useful post, Mainsail. Thank you. Must have been a lot of work.

Re: LED Bulb Comparison !!!

Bulbs have gotten better since 2008, when I originally posted this.....

Still though there are scammers and snake oil LED's out there. I recently trouble shot a "no-light" situation, they were eBay LED's and the emitters got so hot the solder melted and they fell out into the glass globe... Doh'... Owner could have bought MarineBeam LED's and come out ahead after paying me to figure out the "issue"....

I am still a fan of the Sensibulb, what I have on my own boat, but Jeff Field at MarineBeam is the one to beat. These days I buy most of my LED's from MarineBeam (so does IMTRA) top quality, proper circuits and a great company... He's got a lot more than just LED's these days too....

P.S. If you mention to the folks at Sailors Solutions that you read about the Sensibulb here, Nick, one of the owners, has agreed to give 10% off..
Ever since LED bulbs have come on the market, I have been seeking a comprehensive comparison of the bulbs, without too much success. I want to thank you for the time, effort and money you spent on this post, as it has really laid things out so that even a dummy like me can understand it.
Thanks again.

LEDs are semi-conductors. Heat is a semi-conductor's enemy. To get LEDs to emit a bright light they must unfortunately be driven to the point that they generate self-destructive heat. The only way to save them is for there to be adequate heat-sinking to draw the heat away. You can buy relatively inexpensive LED flashlights these days that way out-perform a "traditional" flashlight--even a high-end one from such as MagLight, but you can not obtain a LED replacement bulb for "old tech" flashlights that will make them perform as well, because there's no way to design a drop-in replacement bulb with the heat-sinking necessary top allow you to drive the emitter hard enough to make it perform well.
This should tell you something about the likely longevity of (most?) replacement navigation "bulbs."

I'd have to agree with you on this, Jim. I purchased the proper replacement LED bulbs for our Aqua Signal running lights, with disastrous results. Basically I threw away about a hundred dollars, as they lasted less than a year. Perhaps, if we'd washed the fixtures with fresh water after each sail, as a day sailor might, or each morning on a crossing, they might have held up.
I replaced the fixtures (which actually cost less than the LED bulbs for the Aqua Signal fixtures) with sealed fixtures designed for LEDs and have not had any problems since. How nice to have one's running lights come on when the switch is flipped, no matter how long it's been since they were last used

Re: LED Bulb Comparison !!!

These are exceptionally well sealed. The 8' pigtail is not removable from the light.

The main reason that I did the upgrade was that my old Hella festoon bulb fixtures had shorted out one day in heavy rain. It took me a while to figure out why the breaker kept tripping.

I had to do some drilling to make the fixture fit on my existing stainless steel mounting plates, but it was not difficult. I wish that I had done the upgrade long ago.

A good thought. My nav lights are more likely to corrode and become inop than actually burnout. I don't run at night all that often to really care about power consumption. Are they sealed well from the weather? Form the pics, I can't really tell how I would get them to attach to my current mounts.

Re: LED Bulb Comparison !!!

This game seems to have come up a level or two, since MS first review. Any new intel? For example, the marinebeam direct plug replacement bulbs are simple to install (just plug them in) and much less expensive: $11 a pop, if you buy quantity.

G4 6-LED Side Pin Replacement

Any updated experiences? How about lifespan?

We have 44 fixtures with the old fashioned 2 pin halogens. If we decide to replace them, we better get it right the first time! It's probably the heat that concerns me more than the power draw, they are never all on at once. But the lower power is a big plus.

If you buy from Sailors Solutions you will only get the new ones. They have been out of the old style for a long time. They are just slow to update the web site photos.
