The Exo Terra Repti Glo 2.0 Compact Full Spectrum Terrarium Lamp is a general light source with a high visual light output and a very high colour rendering index (CRI), but a lower UVB radiation. This bulb is suitable for snakes, all amphibians (frogs, toads and salamanders) and nocturnal animals. Plants will thrive under this light as well. It is also a perfect complementary light to a UVB bulb to boost visual light. Fluorescent bulbs lose their UV radiation and approximately 50% of their lighting output quality within one year. Ideal for all reptiles and amphibian, the Exo Terra Repti Glo 2.0 Compact Full Spectrum Terrarium Lamp provides high visual light output, stimulates plant growth, and stimulates appetite, activity and reproductive behaviour through UVA radiation.
