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 distribution, enhancing the ultraviolet spectrum. This daylight bulb emits UVA to support natural behaviors and UVB to promote vitamin D3 synthesis, aiding in calcium absorption. The balanced UVB output helps prevent and improve metabolic bone disease in reptiles. It also provides warmth to assist with 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 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.
