The therapeutic infrared energy produced by this lamp helps to improve circulation and increase healing, providing relief from pain and tension throughout the body. Emitting safe near-infrared energy that penetrates the skin, the powerful lamp treats a large 16" x 12" area such as the back, torso, or thigh. While this generous coverage is similar to a heating pad, the lamp can reach higher temperatures because it has no contact with skin, yielding a more powerful and efficient treatment session. It quickly heats to 95° F, and its soothing warmth penetrates deep into aching joints, muscles, and even sinus cavities. It tilts to a 35° angle for targeted therapy, and its countertop design eliminates the contortions required by a handheld model. Users select their desired treatment length; the lamp shuts off after 15 minutes and has a cooling fan and warning light for safety. Plugs into AC. 11 1/2" H x 7 3/4" W x 7 1/4" D. (5 lbs.)
