Habistat Moon Switch


The Habistat Moon Switch is a light sensor that activates the unit it's connected to when the sun has set or the artificial lights go out. It can be used in various ways, to switch on what your animals need at night: an additional thermostat with its own heat source, for example, or a night lighting system.


This light-activated electronic switch for luminaires goes up to 600 Watts when light levels go down and shuts off again when light levels go up.

The Moon Switch switches a mains power line on and off depending on the light level. When there is light the power will be off and when it is dark the power will be on. The difference between the on and off levels has been adjusted so that the unit does not flicker at the trigger point or turn on and off due to small changes in brightness. Essentially the unit senses day and night and can then turn on any other appliances that are needed during the night.

The range of items that can be plugged in is only limited by a maximum load of 600 watts. Most uses will include turning on heaters which are only needed during the night. One of the major benefits of the "Lunar Shift" is that the natural day/night cycle is duplicated by including the seasonal variations of long summer days and short winter days.

Reptiles that are active at night are as dependent on external heat sources as their daytime active relatives. The main difference is that they are often able to cope with somewhat lower temperatures. Moon switch will turn on these secondary heaters whilst the solar switch will turn off the higher but still needed daytime heaters and brighter lights, it can be used to turn on lights designed for night use.

The red Basking spot lamps are an example of this. Here red light is used to create a warm spot without the distractions that white light would be for nocturnal active creatures. Special fluorescent lamps designed to stimulate moonlight are another example.

Many creatures active at night need to see their prey and cannot hunt in complete darkness. Ordinary lights, however, are too bright and are avoided. The dim light is just right for nocturnal predators to spot their prey, but not so bright that it confuses their natural photoperiod. This means that the essential synchronization involving the photoperiod is left intact, so the animal behaves and reproduces normally.
