Exo Terra Solar Glo (80W): A self-ballasted mercury vapor bulb that provides both intense light, heat, and UVB/UVA in one lamp. At 80 watts, it’s suited for smaller terrariums, offering the benefits of natural sunlight for reptiles – promoting vitamin D3 production, healthy appetite, and activity. The Solar Glo is ideal for sun-loving species; it should be used in a well-ventilated, vertically mounted fixture. It delivers a broad spectrum and can be positioned at a distance to create a proper basking spot while covering UV needs.
