hey John...i looked around to see if i posted about why i made my change last year, but i don't see it, so i apologize if this is a repeat.
there are a few things that i didn't like about the old OceanLED 2010 lights that Formula had put on my 45. first, i kept having to replace either the lights, or the drivers as they are separate on that model. i think 2 things were at play.
the center light was installed below the water line of the bilge. downside here is that the connector is almost always below water, and while it's waterproof, i don't think they intended it to sit below the level of nasty bilge water. i think there were a few times where water got into the connector and caused issues with either the light, or the driver.
also, Formula wired the lights off of the remote control box, using a Bosch style relay to drive them. that's fine, but the lights were daisy chained which causes a drop in voltage as you move from port to starboard. i think this was frying the driver on the starboard most light.
so, the 3116's use a built in driver which means no connection on the back side of the light which fixed the center light issue. then i re-wired everything to use a single Bosch relay per light which gives me consistent voltage across all 3 lights. i haven't had any issues since i made these changes.
since you're looking to make some changes, i thought i'd throw that out there. good luck with your mod's, and i can't wait to see what it looks like!
