The Night Sky LED set imitates the light of the moon and makes nocturnal observations of reptiles and amphibians possible, without disturbing the animals. Advantages of the LED technology are low energy consumption, low heat emission and a long life of the light emitting diodes. Therefore, illuminating terrariums all night long is possible, without hindering the natural nocturnal drop of temperature as with other light sources. Especially nightlight incandescent lamps consume a lot of energy and consequently produce a lot of unwanted heat as well. In addition their ability to illuminate the terrarium properly and allow nighttime viewing is limited.The energy consumption of the LEDs in the Night Sky LED set is merely 0,2W per LED. This is the most energy efficient way to illuminate a terrarium at night.The Night Sky LED set contains 3 moonlight LEDs and an electric transformer, with which up to 6 LEDs can be powered. Additional LEDs are available separately. The LEDs are connected to the transformer by a connector, which makes them easy to install. Mounted on the ceiling of a terrarium, they enable a well-balanced nocturnal illumination of the whole terrarium.
