If it's effective up to 12 inches, at 12 inches the turtle wouldn't be getting much UVB. Personally, if it's a 5.0, I'd have it a few inches closer than 12 inches. Make sure the UVB light is balanced out with the heat light. If it appears that it's bothering your turtle's eyes, then move it back to 12 inches.
