I get readings of UVI 1.0-1.5, using a Solarmeter 6.5, on a Reptisun 10.0 T8 at 10-12 inches. And that's directly below the center of the tube, as the meter moves away from the tube...
High altitude affects most animals adversely.
It reduces oxygen absorption causing difficulties in breathing, dizziness and headaches, also known as altitude sickness.
