It can depend on the ambient air temp in the room the turtle is in. When I used two lights (UVB and heat source), in the summer, when the room one of my turtles was in got quite warm, I would turn off the basking light and he would just bask under the UVB light. In cool weather and the cooler months, though, both lights are necessary (a basking area temp of 88 - 90F is good.)
