Marukan Mesh Heat Lamp Cover 100V/40W Bulb not included (please purchase separately) Cover only (Image 1) Used weekly for cleaning as a winter/summer cooler measure for cockatiels. Power-on confirmed with a regular light bulb (Image 6). I've tried various types of heaters, such as partial and full panel heaters, but 100W and 60W were too hot, 20W was too cold, and the 40W bulb type was the right temperature for the birds. It has a small outdoor hanging hook to prevent tampering, and covering it with a plant greenhouse cover or cloth will further regulate the temperature. They always fluff up their feathers with warm air, looking plump and cute ♡ ⚫︎100V/40W ⚫︎Stainless steel mesh ⚫︎For use with heat lamps
