The tortoise's back-drying lamp useful because its main function is to heat and replace sunlight, so most of the back-drying lamps simulate natural light. If the tortoise can't come into contact with natural light, you can choose to use the back-drying lamp or replace sunlight for a short time.

But different basking back has different functions. For example, UVA lamps and ceramic lamps with lower prices can only be heated and cannot replace sunlight. There are now full-spectrum solar lamps that can replace sunlight. The metal halogenated lamps inside them can replace the natural relationship.

It is better for Brazilian tortoises to bask in the sun, because the sun contains more light, which cannot be completely compensated by lamps alone. Moreover, the quality of sun-backed lamps is uneven, and the poor sun-backed lamps will also affect the growth and development of Brazilian tortoises. In addition, Brazilian tortoises, like humans, need more sunshine to promote the absorption of calcium. Ultraviolet rays from the sun can also kill most bacteria on their carapace, making them less likely to get sick. If conditions permit, breeders had better choose to bask in the sun.

Although Brazilian tortoises are suitable for basking in the sun, they should not bask in the sun for too long, otherwise they are prone to dehydration and death.
