A reptile like a bearded dragon which is native to the baking hot aussie bush worships the sun during the day.
Bearded dragon uv light at night.
Simply put you re bearded dragon s tank shouldn t have any lights running at night.
During the summer months you should provide your bearded dragon with a minimum of 14 16 hours of daytime light and uv exposure and 8 10 hours of nighttime exposure.
Bearded dragons do not need a source of uva or uvb at night.
If you tank temperature falls into the 60 s at night invest in a ceramic heat emitter instead of running the lights 24 7.
Leaving these bulbs on will make your beardie think it s still daytime and can seriously disrupt their sleeping schedule.
But at night time when the temperature drops in the outback the beardie likes a colder temperature.
With a constant background temperature and lighting period this tends not to stimulate brumation hibernation in the bearded dragon.
As such you ll want to turn both their heat lamp and uvb off at night.
You shouldn t worry about your vivarium s night temperature being colder than during the day but you still mustn t let it get too cold.
Instead the basic setup is 12 hours on 12 hours off for both uvb and the basking spot light bulb.
