UVB lamp (nc)

north carolina
my anole kiwi is not quite getting enough UV rays from just the window even through her plants are (I chose plants that could survive with low UV) and I'm a bit worried about her dull brown colour :/ her tank is warm (its spring in NC and its HOT!) and I mist her daily and don't handle her other than her weekly claw and tooth checkups t make sure she has not broke a tooth or torn a claw :balloon: please help
