The Exo Terra Day & Night LED is ideal for reptiles, amphibians, and invertebrates that do not require UVB, such as snakes, nocturnal geckos, frogs, newts, salamanders, spiders, scorpions, and insects. The bright white LEDs provide a beautiful daylight effect. The blue LEDs mimic a moonlight glow, allowing you to observe your animals at night without disturbing their natural behavior. The gentle light from the blue LEDs enables nocturnal animals to search for insects and potential mates in their territory. In complete darkness, these animals would be completely disoriented. Simply press the button with the day/night logo to switch from bright daylight to a blue night light. The Exo Terra Day & Night LED lighting is a practical and energy-efficient way to illuminate your terrarium both day and night. Unlike traditional light sources that waste over 80% of the energy consumed as heat, the Exo Terra Day & Night LED lighting illuminates your terrarium with minimal heat and maximum light output. Since it produces almost no heat, this reduces the risk of overheating during the summer months and allows for a natural drop in temperature at night. The LEDs in the Exo Terra Day & Night LED lighting consume less energy and have a longer lifespan compared to other light sources.
