Nightvision vs. Ultraviolet Perception

[Ulryk]

Nightvision is defined as allowing the user to see in total darkness as if it were normal daylight (not including the power Darkness)

Ultraviolet Perception is defined as perceiving the ultraviolet range of light allowing the user to see in near total darkness as long as there is a source of ultraviolet light.

All the way from full daylight to near total darkness the two enhanced senses work comparably. But in total darkness only one of the two works, yet they both cost 5 points each.

My question is, what is the balancing factor I am missing here? Specifically in a Fantasy setting where there may not be an active UV projector that would enable seeing in total darkness without detection.

This isn't a rules question, it's a game design/philosophy question, and I generally don't answer those. You're welcome to start a discussion over on the Discussion board if you like, though.
