That's why the handbook has that picture that defines the 5 zones but nothing is allowed in that 5'x 5' box directly adjacent to the water's edge but a listed underwater light or a potted deck box for that light.
I have heard a lot of inspectors say they would exempt a solar light since it is basically a flashlight but there is no code to back that up ... nor the flashlight for that matter. They are still regulated equipment by the strictest reading of 725.41(A)(5).
