Navigation Lights

[ebb]

That's a great site. Been there before, but lost it in the internet forest.

They seem to have really good boat specific products, which they say they have tested.

Their navlights are CE. And sound like they are completely waterproof.
That would make them unique!

And they are sailors.

Their navlights look tidy, streamlined.... and they say will do 2NM, or more.
Even emitting thru colored plastic 'lens'. Not sure where we stand on that problem.
Have heard that drastically reduces lumens.

Was unable to navigate Larson Electronics because of language difficulties.
Like the idea of using pull/pushpit tubing for night lights...
MARINEBEAM has those machined aluminum clamps for a range of tube beginning at 3/4".
Evidently they make them for you on order...
But don't seem to have the 'housing' like for pbryant's honkin crabpot lights.

They also sell a portable LED SPOTTING FLASHLIGHT (3 D-cell) that will find
a buoy at 650 meters on a full moon night! (that's what hype says)
{Using a spotting light powered by only 3 D-cells IS a big deal. However, the real deal
would be to have the light supported with a charger*. It would be even better, imco, for
the light to be stored IN the charger - so that the light is always fully charged.
The catalog hype dance also avoids any mention of 'water resistance'. Buyer has to assume
that the flashlight is marinized beyond its rubber on/off button.
Body is tubular. Any time you put it down, it'll be somewhere else, when you look for it.}
But a focused laser-like beam (minimal light 'spill-over') is a big deal in the cockpit at night.

Haven't gotten any yet.

*An onboard portable charger seems like a good idea for small rechargeable batteries.
All-Battery.com sells Tenergy's TN190 AdvancedUniversalCharger which charges NiMH.

Looked for a solar charger. There are no marine versions, so I suppose you go for a
lubber charger that has all the safety features (timer, reverse polarity and short circuit
protection and bad/non-rechargeable cell protection) and is sold through a US company....?
NiMH batteries do not have a great reputation and other chemistries aren't in the
market yet for AAA/AA/C/D/9V batteries. Hopefully they'll use the LiFePO4 chemistry.

Some pricey LED monster flashlights use Li-ion 18650 small round bats which have their
own special lithium charger - but the bats last forever. This will be the flashlight pair
to look for....

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.
