This is the same TC420 controller available here as a combo unit with the Mean Well driver, but this one is designed to run off the stock power supply that comes with a single light. Just plug the driver right into the controller and it will run.
*** You must supply your own 12v DC power source, or be using the stock driver that comes with all light kits sold here ***
The controller will handle on/off and the sunrise and sunset effects. It comes programmed with 11, 12, 13, and 14 hour light cycles. You can also install the editing software on your PC to create, edit or modify the existing programs yourself. It's very easy to learn. Input is 12v DC, max 20amp.
There are currently three light program profiles to choose from: "Standard" , "Xtra" and "XX", they all feature sunrise and sunset effects with a taper up and down from midday peak intensities.
- Standard: 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.
- Xtra: Peak intensity of 100% lasting for 4 hours at midday, with more light on either side of that peak. Best for new vivariums and plant growth.
- XX: peak intensity of 100% lasting for 6 hours. Best for vivs with the highest light requirements.
Dimensions: 5" x 3"
