Heat lamps are devices that emit infrared radiation to provide warmth and comfort. They are commonly used in various settings, such as homes, restaurants, and farms, to keep people or animals warm. Heat lamps can be found in different forms, including overhead fixtures and portable units, and they typically use incandescent or halogen bulbs. These lamps are often used in food service to keep dishes warm before serving, as well as in reptile habitats to create a suitable environment for cold-blooded animals. Additionally, heat lamps can be beneficial for medical treatments, providing localized heat to relieve pain and promote healing.
