Personally, I don't like the LED light bars. They are too bright, and just blind everything except where they shine. IF you need to see something to the side of the boat, good luck, you are blind from the LED bars. They also spook every bird in the marsh. I'm not a fan at all.
I've tried all the lights there is when it comes to duck hunting, and the best, for me, is a 5 million candle power spot light that plugs into the boat. It only shines where I want to see, and it never dies. I've been let down by every kind of rechargeable spotlight there is. I won't waste my money on any more of them.
For the most part, I like to run with just running lights and a head lamp, but the spot light is used for some navigation here and there, and is always kept within arms reach. Its nice to find distant marker buoys, or long distance landmarks. A quick flash of the light is all thats needed.
