well..there is no such thing as "dormancy lights"..unless you are also maintaining 35-45 degrees F..
but if you have normal indoors temps, 70 degrees, then you have far too much heat and not nearly enough light..which means the plants wont hold dormancy, they will "break dormancy" and try to grow, without enough light..which is bad..
but since its mid-January already, its probably best to just leave them alone..
leave them where they are, under the lights, until Spring, then put them outside..
you dont really have any alternatives at this point..
they will probably be fine..
if they remain completely static for the next 2 months, dont change at all, no growth, but also no more browning, then you should be in good shape..you *want* your plants to do absolutely nothing for the next 2 months!
that would be good..
(just a tip for the future..never buy VFTs or Sarracenia in the winter!
