Where is Riverview? Best to not use indoor UV if you don't need it. If you need it, the Arcadia 12% HO bulbs are my preference, and mounting height will need to be set with a UV meter. Usually around 18-20 inches, but through a screen makes this nothing more than a guess.What is the best uvb lighting and wattage for a sulcata? It will be sitting on top of a screen about 12 inches from my tort.
We adopted a sulcata a while ago, knowing nothing about reptiles. We have kept him outdoors during the day when it's warm and sunny and inside during bad weather and at night, but at 33 pounds he is outgrowing the biggest tub we can find and I think it's time for him to have an outdoor shelter. For his indoor light we just bought an all in one recommended by a pet store, which now looking at these threads seems like was a bad choice. Thankfully we live in a place that is usually warm and sunny.A T5 HO strip uvb
And at that distance a 5.0 should be alright.View attachment 316780
