Operation
Light Eco Plus is fully automatic and requires no user operation to perform its intended task of
saving more than 25% of the lighting power on the circuit.
Principle of operation
Discharge lighting such as fluorescent lighting requires high power to start up but once
operating at full temperature and output, can operate at reduced power with minimal impact on
performance while saving more than 25% of power.
Light Eco Plus is a microprocessor controlled device which allows the lights to power up
correctly and, when conditions are appropriate, switches to economy mode and automatically
reduces the power to the lights.
While in economy mode Light Eco Plus constantly monitors the power and returns to full
power mode if required. Typically this will be due to another bank of lights being turned on or a
critical drop in supply power. It may also be because off an operator intervention to perform
lamp maintenance.
User Display
Light Eco Plus has a display on the front panel which gives immediate indication of its operation
and energy saving.
