A closed tank, one with a glass hood or similar, will keep the humidity inside the tank and be fine.
I disagree. While I do use lids and swear by them. Vast majority of aquarium fixtures are made very poorly to the point that it makes me wonder how they passed safety laws. They sell a lot of small stock tanks with no lids, condensers, water proof connections or sockets. If I ever come across a stock hood that uses water proof heat shrink connectors or fancy wire nuts instead of general run of the mill wire nuts(which lead to corrosion) I will be amazed.
I can tell you the stock wiring in the hood for my Mini-bow aquarium would be equal to or worse then in those clamp lights.
