I have a 2005 Hunter 46 LE with overhead flourescent light fixtures. These fixtures draw 1.25 Amps and give out 800 lumens. I found a good replacement for them. A Thin Lite LED742P. The fixture is the same form factor. It measure just 3/8 an inch less in width and length which isnt a problem--there is just a little bit more play around the light. The recessed area in the cabin ceiling is completely covered. Easy replacement.

The LED742P has two brightness levels: 480 lumens @ .24 Amps / 1600 lumens at .8 Amps. This compares to the flourescent fixture: 800 lumens at 1.25 Amps.

You can find them on line for $65 - $90.
