I meant UVB, not UBV. Think Ultravoilet. =)

Likewise, I meant MBD which stands for Metabolic Bone Disease.

I meantioned to leave the heat source on 12 hours. What I meant to say was to leave the light source, UVB bulb on 12 hours during the day. 12 hrs of light/12 hrs of darkness. The heat source should be left on 24 hrs.

Apologies for the misconceptions and/or misinformation.
