Where are you putting your light set up? I use LED's in places where I need light but not necessary to read. I have them on the side of the house, closet, and hallway. I have some LED flashlights that put out a good stream of light. I still like an incandescent to read a book.
When I clicked on your post, it was on the side. Since this was under flounder fishing, you likely want it on your boat or a raft. I think LEDs would be fine for this. I use the LED flashlight to shine down into the water. Maybe some guys who have them can tell you more.
