These are Reptile 5.0 UVB Bulbs,
These are Reptile 5.0 UVB Bulbs, specifically designed for use in terrariums to provide essential UVB light for reptiles. The 5.0 designation indicates that the bulb emits 5% UVB, which is crucial for reptiles to synthesize vitamin D3, enabling proper calcium absorption and preventing metabolic bone disease. These bulbs also emit UVA light, which can improve feeding response, breeding behavior, and daytime activity levels. The 15W Equivalent indicates that while the bulb itself may not consume 15 watts of power, it provides a similar light output to a traditional 15-watt bulb. These bulbs are often compact fluorescent lamps (CFL) and are designed to screw into standard light sockets, making them uncomplicated to install. They are suitable for a variety of tropical and subtropical reptiles, such as turtles, tortoises, bearded dragons, iguanas, and chameleons. It's important to replace these bulbs every 12 months to ensure the proper UVB output.
