I can wait for a while longer, though am lusting after an LED anchor
light.
You will be waiting for a very long time. An anchor light has to be an
all around white light visible for two miles. The problem with LED's is
they are like little spot lights focused by a rounded lens. Very little
side illumination comes out of them. I suppose you could make a sphere
with about forty of fifty bright LED's and it might meet the legal
requirements.
Putz...you living in the 1960's? Here is a USCG approved Anchor light
with 1 LED.
Just Google OGM LX:
The OGM anchor light requires only one Luxeon LED! An optional
photocell automatically turns on at dusk, off at daylight, allowing
you to leave your boat at anchor for days. The low power draw can be
replenished during the day with a small solar panel to charge your
boat's battery bank.

But, I, Wilbur Hubbard, have a better solution. If you have an inverter
aboard simply buy and plug in an extension cord long enough to go up the
backstay to several feet above the boom. It can be fastened to the
backstay with black "tiewrap" wire ties. Plug one of those little 4-watt
automatic night lights into extension cord but take the incandescent
light out and install a 4 watt compact fluorescent such as a Sylvania
Decor 15. Make sure the little night light fixture is held by the cord
in an upside down position. For 4 watts of power you get 15 watts worth
of lumens.
Ugggh..
