I just replaced all but one of the interior bulbs in Legacy
with LEDs. I have a detailed description of the bulbs I used with photos of them installed at "Legacy": a boat, a family.: LEDs
FWIW, they are all warm-white bulbs and range in cost from $9 to $16.
I got more light out of the LEDs than the 10w G4 bulbs that were in the boat and significantly reduced current draw and heat. Those 10w Halogen G4 bulbs get REALLY hot.
