> are there fluorescent refits that folks have done?

I replaced the stock Westy fixture with a Thin-Lite 15 watt,
then added an 8 watt over the sink.  I really like the
Thin-Lites--sleek, well-made and good looking.

The 15 watt draws 1.3 amps; the 8 watt 0.9.

Both from Northern Arizona Wind & Sun:

I've bought 12V LED stuff from TheLEDLight.com:

(although not for my Westy--for a 12V cabin system.
They have a 25 watt bulb in warm white or daylight
that has a standard screw-in base so "regular"
fixtures can be used.)

FGI: "marine cabin led light" and you'll hit a jackpot.

I have a couple of these--one over the passenger seat
and another for the bench seat:

scroll to second group, LED Cabin Light.  I have the 3 bulb
and they are not very bright, but my eyes adapt.  I'd
wish for a 4 bulb; I have not seen the 6 bulb.
