I guess it all depends on what you you want your spreader lights to do.
Personally, I dislike bright white lights on a boat, with the exception of a spot light.We use our flybridge a lot at night. For me I like a warm light that puts out enough light to see what we are eating and where I put the wine bottle. We have two old fashioned spreader lights, about 150 watts each.
Quite often after dinner, if the moon is up, we turn off the lights and chill. As most of our cruising is in national parks, hence no houses etc, it can be quite magical-until someone knocks the wine over, because we can't see what we are doing!
