This is what I did on Gadabaut. The fixtures in the photos, are low voltage lights, designed to be on a track. The AC transformer that came with these lights, was 12 volts AC. But the light itself, does not care if it is AC or DC at 12 volts. Yes, there was a little engenieering involved, but not hard. Gives off good white light, and if you wish, there are LED bulbs for the same. In 11 years, I have never burned out a bulb.
I did this for all the overhead lights in the salon, and added 2 more in the valance over the port satee, for reading....and the units are on a swivel, meaning that you can direct them to spot light your reading or your dinner.
The stock overhead lights that comes with GB's are....well...crap...for seeing and or reading...
