Depends on what type fishing you are doing at night; Bluewater LED low intensity is meant for something like crappie fishing in open water just so you can see your line. Bluewater LED High output are for something like bank fishing for Bass or when you need to see how far from the bank you are located.
Then there is a sting lighting Ultraviolet that I sell in 16' lengths. If you have a rub rail with a rope insert, or a 1/4 to 1/2 inch insert you can pull out, they fit right in the rub rail. You can illuminate the entire side of your boat.
You can also mount the Bluewater LED this way with the same rub rail set up.
