7+ years back I had upgraded my R / G nav lights to 2 nautical mile units by Innovative Lighting, then Capt Kevin (Megabyte) did the same and documented it as this post here:

Here's another discussion on LED all-arounds lights:

For my all-around light, I simply swapped out a non-LED one for an LED by Perko, IIRC, but this was just 2-years ago. The supply of marine LED products today and even 2-years ago far exceeds what was available many years ago. That said, I do like the low-profile bow nav lights by them.
I want to replace some of my high density led in my desk with a G4 disc type led replacement but it's a type T3 lamp?
They are the puk Flexible LED Strip Lights that came with 20 watt 12V (I think 12V) holagen led strip
in them, But it's A to hot of a bulb for me and B too much power loss for how long i leave them on for my desk plants.
