What would drive me to go with either of the LED based solutions
discussed in this thread is their low power usage. I have the Perko
two-bulb light where each light is 750mW or 625mA for a total of 1.3A.
I have Trojan T105 Golf Cart batteries rated at a little over 200AH of
which by the rule of thumb I can only use about one-third or 70AH. If
I'm at anchor and run my anchor light for 10 hours, this comes to 13AH
just for my anchor light. This is nearly 20% of my total power budget.

Once I had to send a professional up my mast rather than doing it
myself. It cost me $120. It's good to calibrate things. These units
have lifetimes in the 10s of thousands of hours.

I've found a bunch of stuff on replacing the incandescent bulb in the

anchor

light with an LED array. But I haven't found a schematic of how to do

this.

Any help? I'd like to build an array of up to 18 super bright LED's, with

a

regulator. Any ideas?

For what size of boat is this anchor light for???

3600 planes with transponders are burning 8-10 million
gallons of kerosene per hour over the USA. R-12 car air
conditioners are responsible for the ozone hole, right?

For most anchorages, we prefer an anchor light much lower than the
masthead. While it's traditional, and easy, the rules don't require a
masthead light, and we think a light hanging in the foretriangle or
off the boom is more easily seen by smaller boats. You can use a six
volt lantern battery for this.

see Colregs, Rule 30(b) "A vessel of less than 50 meters in length may
exhibit an all-round white light where it can best be seen instead of
the lights prescribed in paragraph (a) of this Rule."

The caveat in Rule 30(b) is merely to say that smaller boats only need one light, not two.
There is nothing that implies that an anchor light must be at the masthead, it must be
"where it can best be seen." When there are two lights, the forward one must be higher.

One can make a good argument that "best be seen" is not at the masthead if the other boats
are small.

Like most sailors, however, I use the masthead light, but I often add a Davis Megalite as
a second, lower light in the cockpit.

I agree. We hang a battery anchor light, wither in the foretriangle or
under the boom tip, when we are in an area with lots of small
motorboats around. A light 60 feet in the air might never be noticed
by someone buzzing around on a sea-doo-doo.

18 LEDs, regulated... and legal... why re invent the wheel?

I bought one, it was easy to install (no polarity issue) works like a
charm, is easily the brightest anchor light I have seen and draws
90MA.

A bonus is that it is distinct! Same differance as the "blue-white"
headlights and the ones on my car. They stand out from the rest.

Just doesn't seem right, though, unless it's an oil lamp running on real
whale oil, does it?

Presents a problem, do these things opperate at night without a headlight?
I don't think they have lights. Anyway. my boat has reflectors viewable
at any angle or position. So does the trailer.

Not necessarily legal. Anchor lights are type approved with a specific
bulb, and this ain't it.
