My boat has LED lighting throughout the cabin, but it was older tech and the color was too "cool" for my taste. Changing out most bulbs with newer "warm white" replacements was a 2 minute job and transformed the cabin from "harsh" to "cozy"
But the galley had those "puck" style under-cabinet lights. Not only were they the harsh blue/white color, but the coverage was uneven, and there were only 2, not enough to light the entire galley. Here is the before:
these had to go!
I bought this LED strip light:
Since I was going to cut the 1M section and make two strips I ordered additional end caps and mounting clips for the channel (~$4)
The LED strip has 3M double sided tape on the back, so just peel it off and stick it to the channel. The strip can be cut to almost any length you desire. You can cut it every 3 LEDs, you can see the cut mark in this picture (just above the bottom-most LED)
You can solder your leads to the pads on either side of the cut. I cut a few 3 LED segments to practice soldering it. It takes a light touch since the strip is small and thin. It heats up very fast and can be damaged if it get too hot.
Here's the result, for under 30 bucks:
