Your setup is pretty similar to mine (lights, cage size, etc). I have a female so I don't expect her to get quite as bright as some of the others I see on here.
Anyway, I would look into one of those cool mist humidifiers if I were you. I have to run ours almost all day right next to her cage to keep it around 50% most days... depends on how much we have to run the heat and what the weather outside is doing. I need to get one of those long tube type UVB bulbs as well.
