Real world lighting costs...LED

Yesterday I was at the local marine store and spent some time looking at various LED lights for the boat and was not overly impressed by the quality of the various LED light fixtures but was impressed by the hig prices... and not in a good way!

Why is it that a so-called, made in China marine unit with three LED's not using tinned wire or marine friendly materials, costs over $100?

While at the same time I can buy a rechargable LED worklight with 78 LED's with charger for less than $40?

This worklight looks kind of neat and I will be getting one or two to play with and see how they work...
