    dim led lights on 4788-gctid345423

    I recently replaced all the halogen 20watt bulbs with led fixtures and was impressed with the results. I now notice that the fixtures in the mid cabin and master do not have the same brightness as the pilot house and the salon. Anyone have any answers for this problem? Thanks, Henry

    As far as I have read, that's normal for LED lights. They do dim over time. Makes you wonder how the new flat panels TVs with the LEDs will look in a couple of years. Plasma for me thanks!!

    Here's a piece of an article about that below.

    The most common symptom of LED (and diode laser) failure is the gradual lowering of light output and loss of efficiency. Sudden failures, although rare, can occur as well. Early red LEDs were notable for their short lifetime. With the development of high-power LEDs the devices are subjected to higher junction temperatures and higher current densities than traditional devices. This causes stress on the material and may cause early light-output degradation. To quantitatively classify lifetime in a standardized manner it has been suggested to use the terms L75 and L50, which is the time it will take a given LED to reach 75% and 50% light output respectively.[46]



    Although they draw a lot less juice, I've never really been a fan of the light they produce. Just seems to cold to me. Only place I use them is in the cupboards and lockers. I have halogens with dimmers everywhere else.

      I found out the problem was a poor wall switch connection. Thanks for the additional information.

        Did you find some affordable LED assemblies?

          If you're just looking for bulbs, the best place I found was hero-ledstore.com - you can get the replacement for the 10W halogens for $4.14 each:

          Service and quality was excellent.

            I bought my leds through West Marine and received a discount by purchasing though our yacht club. I saved some cost by the placement of using the 8 led fixtures where brightness was not a factor and the 16 led where light was needed such as in the galley. The biggest problem was the hole size was different but made a templet of the correct size which kept the hole saw from wobbling.
