I just put in H4 LED's in the cabin today
and they are great, a bit whiter and not as yellow and not as strong as the halogen but cool to the touch and far more energy efficient I'm sure... the heat was most noticable and the light looks more than bright enough in the dark. the ones I have had 12 LED's I think and needed no change in the fixture at all, easy off and on.I'm planning on climbing the mast to find what bulb I have before ordering the LED, if anyone has a charleston spar 361 99 (or round that time) who knows what bulb is on top I'd sure appreciate a tip.Gaute
