Will NAN lights really improve arowana's colour?

I see a few threads on this topic. I have never used it. What does it do, or suppose to do? I understand that it is suppose to enhance arowana colours, but how does this do it.
Does it mimic natural sunlight, that tans the aro, just like the sun would do to humans.

I have never used NAN, but i have an OTTO. It does not mimic natural sunlight, does not tan the aro. but it does turn your aro and everything else in the tank really red. I think its great for display, but it does nothing for tanning.
