The 75W full-spectrum halogen lamp is made of high-quality glass and features a durable filament designed to provide consistent performance and three-dimensional light reflection, enhancing the ultraviolet output. This daylight bulb emits UVA to support natural behaviors and UVB to aid in vitamin D3 synthesis, helping reptiles absorb calcium effectively. The balanced UVB output helps prevent and improve metabolic bone disease in turtles and other reptiles, while also providing warmth to support digestion. This full-spectrum heating bulb is easy to install and fits standard E27 screw bases. Suitable for a variety of reptiles and amphibians, including turtles, lizards, bearded dragons, snakes, frogs, iguanas, tortoises, and chuckwallas. The heat lamp operates at AC 110V-120V, 75 watts, with approximate dimensions of 2.0 inches in diameter and 2.0 inches in height. PLEASE NOTE: 1. Use 3-5 hours per day, as extended use at high temperatures may reduce lamp lifespan. 2. Do not turn the lamp on immediately after turning it off, as a sudden electrical surge while the bulb is still hot may damage the filament. 3. The bulb surface becomes very hot during operation. Do not touch with bare hands and maintain a safe distance between the lamp and your pet.
