Habistat Sun Switch
The Habistat Sun Switch is a daylight sensor that activates the unit it is connected to only when the sun is shining or artificial lights are on. It can be used in various ways, to switch on what your animals only need during the day: an additional thermostat with its own heat source, for example, or a daylighting system.
This light activated electronic switch goes up to 600 Watts, when light levels rise it turns on and when light levels drop it turns off.
The Moon Switch switches a mains power line on and off depending on the light level. When there is light the power will be on and when it is dark the power will be off. 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 switch on any other appliances that are needed during the day.
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 day. One of the major benefits of the "Solar 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 in the daytime depend on heat sources that are comparable to the sun, the sun switch will turn these secondary heaters on for you, it can be used to turn on lights designed for daytime use. This means that the essential synchronization involving the photoperiod is left intact, so the animal behaves and reproduces normally.
