I have had no problems with LED lights in the cold, hot, rain or what ever. They are on my boat 24/7/365 and always work when I turn them on. They are way better than the old style lights and seem to get cheaper every day.
They were sweet this past winter when striper fishing at the steam plant in the cold of winter. I did not feel unsafe staying after dark to fish.
If I had to do it again, I would probably put the long UV strips like MPD816 did and then use the narrow beam shorter bars for blue lights to light the shore up. I also like the idea of using dimmers. I never thought of that.
I think most everyone will have LED's on their boats in the next few years as they are that much better than any lights I have used in the past.
