Cylindrical heat lamp, 100V, 20W, with a power cord approximately 1.5m long. - Voltage: 100V - Wattage: 20W - Shape: Cylindrical Thank you for viewing. Used for several months. Operation confirmed. The lid is stiff and won't open, but someone with a strong grip might be able to open it. I will ship it as is because I can't clean the bulb inside. The bulb inside was tilted from the time of purchase, but it worked without any problems. There are some dirt, small scratches, and stains from use. Please refrain from purchasing if you are sensitive to these issues.
