Control System

---

Pacific Sun knows that power is nothing without control.  The most notable feature of their new T5 lighting system is its four channel wireless (via Bluetooth) control system.

Pacific Sun provided us a first look at their “Bali” control software, which works with PC, Mac, and Android platforms.  Looking over these screenshots reveal a software that is impressively full-featured, flexible, and easy to use.  All Diuna units feature four channels of independent control for the 8 to 10 T5s housed in the fixture.  Users can assign different on and off times for each channel as well as set custom moon cycle simulations.  Speaking of moon cycle, all Diuna models come with built-in a LED moonlight with a special lens that distributes the moonlight over the length of the fixture.

The software will also calculate bulb usage in order to notify owners when it is time to replace bulbs.  This is particularly useful because of the separate control channels.  Each channel can operate for differing (user-specified) durations.  Instead of replacing all bulbs on an estimated yearly basis, users can now replace them based on actual run-time.
