These controllers have to be extensively tested to make sure the preloaded program modes run exactly as you have selected. These full function controllers come with 3 time cycles and 4 different intensity profiles for a total of 12 ready to run plug and play options, giving you the ability to mimic seasonal changes as well as adapting to the growth lifecycle of your vivarium.
For all the various controller/driver and configuration options here, channel 5 will be reserved for the nightlight option, with channels 1 thru 4 used for daylight control.
Each cycle time has four iintensity profiles to choose from: "low", "med" , "hi" and "XX", they all feature sunrise and sunset effects with a taper up and down from midday peak intensities.
- Low: peak midday intensity of 100% only lasts for 30 minutes. Insitu vivarium owners find this one useful, as well as low displays (under 18" tall)
- Med: Peak intensity of 100% lasting for 2 hours at midday. Best for vivariums that are already grown in, or you prefer to have less light for the sake of the animals. Plants grow very well under these balanced conditions. Intended to most closely mimic solar cycles.
- Hi: Peak intensity of 100% lasting for 4 hours at midday, with more light on either side of that peak. Best for new vivariums and high light plant growth.
- XX: peak intensity of 100% lasting for 6 hours. Best for tall vivs (36 to 48") with the highest light requirements.
Dimensions: 5" x 3"
