LED's for the Boat

My boat is 45 years old. I've got three different kind of bulbs in the cabin and a couple different kinds for navigation and another two for the trailer. They're all incandescent so I thought I'd look into LED's...but I wanted to compare the different kinds of LED's against my current bulbs. This is far from a scientific endeavor, but it did satisfy my curiosity.

I made a rack to hold 11 lights and used a 120vac to DC power source. I ran it at 14.2 volts so when they were all lit I still had 12vdc.

The main comparison was the first 4. 

#1 is an 1157 on low. That's the bulb used for tail/stop on the trailer - it was in the tail light mode.

#2 is an LED version of the same 1157 in the same tail light mode.

#3 is the same #2 but in both tail and stop mode

#4 is the same as #1 in both tail and stop mode.

#6 is a nav light

#10 is a stickyback array that came with adapters for several different sockets.

My favorite is the one that looks like a paddle - it ran  bright and cold. It only has a single active side, but it lights either way. I'm using it here in a bayonet adapter for the red and green - it fits directly in some interior lights.

My anchor light(s) are similar to #3 but with the marine double bayonet base.
