They are not advertised as anchor lights. No way to power them other than
the internal battery and no way to power them off when not needed.

Unfortunately, the only one I really think would be adequate is the
largest and most expensive.

The English company that actually makes them has a less expensive
version than even the 501 but it has a max range of 1 km, not enough.
It might be good for long term mooring but not as an anchor light.

For now, I do not think the solar cells are efficient enough to really
power an anchor light. maybe in 5 years it will be practical.
