This is a bit old, but I used it a few years ago when I had small animals. The heater itself and a thermostat for temperature adjustment. - Product Name: Pet Heater 100W - Included: Orange heater cover, two light bulbs (40w, 100w) Both have been confirmed to heat up. - Thermostat for temperature adjustment It worked fine before, but please understand that I haven't confirmed whether the current temperature control is accurate. (Power turns on) Thank you for looking.
