Exo Terra Solar Glo 125W Mercury Vapor Bulb
The Exo Terra Solar Glo 125W combines UVB, UVA and high-output visible light and heat in a single mercury-vapor lamp, making it a cost-efficient replacement when you want fewer fixtures and integrated spectrum for heating, lighting and UV needs. Its long throw and stable multi-spectrum output give a technical advantage over separate T5 tubes or standalone basking lamps, though it has a higher upfront price than simple spot lamps or ceramic heat emitters.
