Like the title says, how long after lghts out until RETF usually wake up?

I just got two females on Sunday, their lights went off about 4 hours ago and they are still sleeping.
Is this likely a symptom of stress? Or is something else up?

I know at the N.A.R.B.C show in Arlington the guy I purchased them from was keeping the girls awake to keep them active. Think they are just trying to recover from two days of little sleep?

I'm a new frog owner so obviously everything is freaking me out.
