This is a Dori Shokai Dantotsu (Dantotsu) S-size heater. Features: The "Dantotsu" is a far-infrared upper heater. The "Dantotsu" uses special insulation and technical ingenuity to increase the radiation effect, radiating over 90% of the heat downwards for powerful wide-area heating! Also, since it does not use a heat bulb, it is exceptionally durable and economical. Furthermore, it can be used day and night, eliminating the need for a night-time heat bulb. *It is not completely waterproof and cannot be used underwater or in environments where it will get wet. This heater is ideal for snakes and lizards that may be burned by wrapping around lights! For turtles, which have their lungs directly under their shells, heating from above is effective.
