The linear Repti Glo bulbs have a higher output and divide the energy more efficiently over wider terrariums.
Exo Terra has a full range of seven sizes of each type, Repti Glo 2.0, Repti Glo 5.0 and Repti Glo 10.0, in order to cater to any terrarium size. The longer sizes can even be placed on multiple terrariums.
Repti Glo 5.0 spectrum
The Exo Terra Repti Glo 5.0 has a moderate to high UVB output, similar to that of shady environments such as rain forests and other tropical locations. Reptiles living in these habitats receive less UV radiation because of the many climatological conditions (fairly high humidity, changes in weather, etc) that prevent direct sunlight from reaching them or their basking sites.
