How To Provide UVA For Your Bearded Dragons

Here’s how to provide UVA to your bearded dragon:

    • Set up a UVB light in the reptile’s enclosure. These lights come in a variety of sizes, shapes, and types. Bulbs need to be changed every 6-12 months.


    • Include a surface material that reflects UVB rays, such as white sand.


    • Allow natural light exposure, if possible. Place the enclosure in a spot that allows for a few hours of sunlight.
