Controlling the output for proper exposure. Another issue is dealing with shadows. Ring flashes deal with this issue by controlling each side or tube independently and also controlling the output independently.

It is possible to build a LED light that would be good, but most of the ones I have seen are not the greatest. This is just my opinion based on my experiences.
