Navigation Lights

Even emitting thru colored plastic 'lens'. Not sure where we stand on that problem.
Have heard that drastically reduces lumens.

ebb I was able to get replacement clear glass domes from Jim Reineck for our original fixtures. I also had to replace the part where the electrical wire ties into the fixture and he was able to provide those parts to me also.


Here is the link to his website..........

Here are how the new LED bulbs look in the old fixtures.

Nice looking lights!

Since LEDs have good color purity, there is not much of a point to using colored lenses. Colored lenses only reduce the intensity while performing no function.

What you can not do is project a white LED through a red or green lens and expect to get much colored light out. LED lights are "non black-body light sources". An incandescent lamp - which is a black-body source - projects light from a very hot filament, and it's spectral characteristics are spread out over a wide range of colors. So it behaves like a black object (body) heated to a specific temperature (called the color temperature) measured in degrees kelvin (degrees Celsius above absolute zero). The hotter it is, the more blue light is emits. An incandescent filament at 3,000 degrees kelvin produces a little blue light, more green, lots of red, and even more infrared (which is wasted energy). Since an incandescent produces light across the entire visual spectrum, you can filter it to one color. LEDs, even white LEDs, don't have an even spread of colors, and although they may appear to be a mix of all colors (white), they actually have sharp peaks and valleys in their spectrum. When the "white" LED light is passed through a colored filter, only a tiny percentage of the light of one color will pass through. Filtering a white LED to produce the same amount of green or red light may require more power than an incandescent lamp - negating the whole point of using LEDs.
