Thanks!
No, a few days without UVB is ok, it'd mimic overcast weather. If it goes on for more than a couple days, add calcium powder to the food. I would try not to go longer than a 3-5 days though. It can take very little time (only weeks) for metabollic bone disease to start in diurnal herps, so you'll want to give it daily UVB exposure 99 % of the time.
