At the same time, the UVB light of this heat lamp can accelerate the synthesis of vitamins, fully absorb calcium, and avoid diseases caused by insufficient light. So it's a must for your crawling pets in your house. Two bulbs of 25W and 50W are also included.【Adjustable Temperature and Brightness】: The land turtle lamp is equipped with a rotary knob, which can freely adjust the required temperature and brightness. The temperature can be lowered in summer and higher in winter, to prevent the turtle from being burned due to the inability to adjust the temperature.【Sturdy Ceramic Lamp Head】: The UV heat lamp head has been upgraded and made of ceramic. Compared with ordinary copper lamp holders, it is stronger and has a longer service life.
