If you are a
single ended ceramic metal halide lamp, it doesn’t matter
If you use a UVA heating lamp, because its brightness mimics the sun is bright, if you warm up one day, the tortoise will not sleep at night.
Therefore,
night heat lamp are needed to warm up the night lights. The simulation of the moonlight is not bright enough to affect the turtle's sleep. At the same time, the uvb lights are also needed.
UVA heating effect is obvious, increase the temperate appetite of the turtle, uvb promote the calcium absorption of the turtle is also very important, this is used during the day, of course there is natural sunlight that is the best.
In the evening, only warming is needed. The night lamp can be used. The ceramic lamp has a much better heating effect than the night lamp. It also has a long life and a low price. It does not emit light. However, the ceramic lamp is heated by infrared rays, which may cause water shortage in the turtle body. It is very bad for turtles that are easy to rock.
