aCappella's anchor light...
The highest fixed item on our boat is the anchor light. While we can tilt down the VHF and HF radio antennas for bridges, the light on top of the arch only comes down with great effort. It sits a full 20 feet above the water surface. We know that any bridge lower than about 20' must be lifted in order for us to proceed through it.
No, we didn't hit a bridge.
In 2005 I changed the bulb in the anchor light. It's an expensive halogen light that we turn on through all darkened hours at anchor. It has burned brightly over many nights for us warning other boats that we were anchored. Because of its technology, it consumes a fair number of amps to provide the required 2 mile range.
A couple of weeks ago there was a wonderful new LED replacement bulb at a great price from Defender (part of our Defender 1st program with them). We purchased a couple of the bulbs with the intention of using one for the anchor light. It has the required range but burns less than 30% the amps of the previous bulb.
So I carefully removed the sealed fitting that has guarded the existing bulb from wind, rain, and even hurricanes through the last 6+ years. When I got the housing off there was an unexpected finding inside. It was almost filled with dog hair.
Can anyone come up with an explanation of how this sealed container could be filled in this way?
The new bulb is wonderful, bright, and saves a lot of power.
I'm starting to wonder what my lungs look like.
