Since I have started a quest to find a set for my 47' Post I guess you could say that I've seen them all. We ended up going with the "Shadow Caster" line. Simply put, the brightest UW lights on the market... almost 3000 lumens. We installed 3 of the bimini blue lights and they are awesome. We were docked next to "Trader Hill," a 88' Hatteras out of Panama City with a set of $ 2400 Ocean LED's and we were BY FAR brighter and saturated the water better.
They are flat mount with a rear mount wire in the center. They are wired for a strobe option although the company that makes them hasnt released the strobe controller yet... but when they do, all you will have to do is hook up the extra wires.
They get $ 679 each.
Food for thought.
