Based on the recommendation for fish tank sizes I'm going to assume this is 100W but might be 200W. Adjustable dial let's you control the temperature settings. Removed from packaging but never used. Has been tested and is working. Perfect for everyday use. first-class materials and excellent craftsmanship ensure long-lasting durability.
