Crypts are known as low light plants because some commonly kept species
tolerate low light, not because they grow better in low light.  Given
enough light some Crypts are robust and aggressive plants.  Some species
(crispatula and ciliata come to mind) don't do at all well in low light.

Yes, but...  Unless your lighting is unusually efficient 80w/35 gallons is
still not real bright, so you might not see much difference.  Their
recovery from the move and adaptation to brighter light may not be

That might be fine.  Keep in mind that fertility has to be maintained.
