New LED's won't work...

[hellosailor]

Just to point out, an LED is always, inherently, polarity sensitive. Those LED assemblies that say they are not polarity sensitive are using a bridge diode circuit to address the problem, and in doing so, they will consume slightly more power, and require something like an extra half volt from the power source.

Not a HUGE issue, but "there ain't no such thing as a free lunch". They're convenient, but not necessary for most users and most installations. In any standard "center hot" socket they're not needed, but when things haven't been wired up conventionally, they're a quick fix.

Superbrightled.com and for nav lights Dr. LED at Wm. Red nav light HAS TOO BE RED Other wise it be pink the CG does not likeeace

Thanks in advance.

With the info provided all I can ask is: Did you remember to put the switch ?

This would no be an issue if your DC negative were bonded to the AC ground as it should be.

Many of our fixtures use the G4 mount, so we bought these. For the fixtures that use the BA15D mount, we got these. This strategy allows us to use a single bulb type (G4) for all fixtures. Adapters for the G4 to just about any 12V socket are available, and there are hundreds of sellers selling the G4 bulbs; simply look for the best price per bulb.

Hi, I used Cjinese Led strips, blocks of LEDs and M16 lights to make all the lights on my I30. They look good, have dimmers, and were all very cheap...just a little time to make them. I even have back-ups for them as they are so cheap...AND, be careful...all thos big bucks lights...where do you think they come from...Yea, China! Why pay the middleman...

I'm in complete agreement. Much of the early hype about specific "marine" LED's was just that ... hype, as an excuse for ridiculous markups.

We have gone this route as well. In addition we used the strip of leds in the engine room. qty 2, 4' long strips (adhesive backed) attached to 1" wide pvc furling. It lights up the engine room light daylight. I have a walk in engine room (well crawl in)

I had the chance to compare the Kawell 90 degree 18 watt flood lights to the 18 w floods at the local marine store. They look the same and when I ran them at various voltages they each drew the same current more or less. This tells me that they have the same circuitry inside.

The "name brand" floods were $90 each. The Kwell were $18 for 2.

The owner asserted that the name brand units were better than the Kawell units. But from observation and the current draw test they appear to be the same units.

Anything with "marine" in the name is likely a rip off, but there is a qualitative difference in LEDs. Self regulated are generally better quality and tend to live much longer...just dont buy from a Marine shop. You can find from many other sources.

Caveat: my experience with Marine Beam has been quite good, but of course not the least cost option.

I dunno, almost ten years with the cheapest household (Ikea) ones available at the time and they are still going. I'll stick with the cheapies.

Right. With the old bulbs polarity didn't matter and often the lights are wired wrong from the factory. Sometimes they even used the same color wire for both legs so even the installer didn't know which was which. It just didn't matter with incandescent bulbs.

At least you can flip the wires at either end.

All cheapies may not be created equal. I bought some cheapies a few years back that were very short lived.

Do the Ikeas have any form of regulation (built in or external)?

Make sure you did not inadvertently by 24 V bulbs. They will look the same as 12 V bulbs.
