I think anchor lights
low are far superior. If bright enough they also illuminate the superstructure making distance judgments for approaching boats much easier.
The only problem is mounting them where they can be seen 360 deg.
To overcome this I use 2 Bebi Owl lights
. The power draw of these is very low, less than ˝ my previous LED anchor
light , so 2 can be used for no more electrical consumption.
