The Pet Heating Lamp comes in a variety of wattages - 25W, 50W, 75W, and 100W - making it suitable for tortoises, snakes, spiders, and lizards. Made from durable ceramic material, the lamp is available in black and features an E27 power interface. Please note that due to lighting and display differences, there may be slight variations in appearance. Additionally, it is normal for the surface of the ceramic lamp to show cracks, but this does not affect its functionality. Please read the product size carefully before purchasing. Thank you for your understanding.
