This is a set of a 40-watt heat lamp and a thermostat. Suitable for reptiles, rabbits, chinchillas, guinea pigs, hedgehogs, degus, sugar gliders, squirrels, hamsters, and parakeets. The thermostat and bulb were purchased new, and used for a total of two seasons. The heater body was purchased used and used for two seasons. There are no bite marks on the cord, but there are some marks near the base of the sensor. Please check the images. It heats up well. I also have other items for sale, such as heat lamps, panel heaters, and small animal heaters, so please take a look. Please read my profile before purchasing.
