9. Lamps temperature recommendations：
Re：The ambient temperature should be maintained below 30 degrees Celsius, and it's normal the lamp shell temperature below 75 degrees Celsius. If you find that the temperature is too high during usage, check the ambient temperature, and then remove the power supply to the outside of the tent, increase the fan above the lamp.
