This device produces blue light, which is known to harm animal vision and disturb circadian rhythms. Nocturnal and crepuscular animals' eyes are very sensitive and able to see well even in what human eyes perceive as total darkness, making night lighting unnecessary.

If you are looking for non-UVB daytime lighting for your pet's terrarium, we recommend the Exo Terra Natural Light, 26w and Exo Terra Compact Top as an alternative.
