I used this for my cockatiel two years ago. There is some dirt on the top. It doesn't affect use. Used for only two seasons. Still usable. Operation confirmed. This is a 40W light bulb heater that radiates infrared rays to warm your pet's body. It emits only a small amount of light, so it won't disturb your pet's sleep. Protected by a steel cover, it prevents pets from playing with it. It comes with a hook for easy installation. - Voltage/Wattage: 100V/40W - Design: Cylindrical, mesh exterior - Power cord: Yes, with plug - Colors: Orange, White
