AstroDIM

AstroDIM is an autonomous five level (1 Power ON & 4 Dimming levels) dimming protocol. It provides multi-stage night-time power
reduction based on an internal timer; there is no need for an external control infrastructure. The ECG is automatically aligned to the
on and off times for the street lighting and provide a defined output for the particular period of time. Compared with conventional
systems there are significant cost savings. AstroDIM is designed for dimming without any external control wiring. Therefore,
AstroDIM helps to save energy, extend the life of the driver and the LED module and reduce light pollution, even if only a power line
is available. In AstroDIM operation, the driver executes a preset dimming profile, which can be reconfigured via the OT Programming
Tool. The autonomous dimming is regulated by an integrated timer (no real-time clock), which adjusts the dimming profile according
to the previous night (operation from switch-on to switch-off).

Constant Lumen Maintenance

The Constant Lumen Maintenance feature of the OTi100W helps to maintain the required lumen output of the fixture at a constant
level throughout its lifetime. In general LED’s lumen output will depreciate over time and in order to maintain sufficient light level
towards the end of lifetime, the LED’s are driven at high current initially and will result in more energy consumption. The constant
lumen maintenance will give the flexibility to drive the LEDs at optimal driving current throughout its lifetime. This helps in energy
savings, constant light output and enhanced reliability of the system.

Note: Step-by-step instructions are outlined in the OT Programmer User Manual embedded in the software download.
