Hi and welcome!

Chameleoking is correct. No lights at night and no red or colored lights at any time. They need a 12 hour on/off light schedule and they need total darkness to sleep properly. Usually a little bit before lights out, chams will start heading to their sleeping spot. Yours may not yet have her schedule or her favorite spot. Although it is bizarre to us, they sometimes sleep hanging onto their screen and even upside down. Colored lights can damage their sensitive eyes. For proper uvb, you’ll be wanting to get a T5 fixture with either a ReptiSun 5.0 or Arcadia 6% uvb bulb. It needs to be long enough to span the width of your enclosure. Unfortunately the coil/screw in bulbs are able to provide adequate uvb levels only about 2-3” away. Your night time temp drop is perfect! Veileds can handle temps as low as mid 50’s (although we try not to cool them off that much).
