ERROR OR WARNING INDICATIONS
One rapid red flash with
long off interval
Too low voltage
Input voltage is too low
Ballast power drops to 50%
automatically
If used it with 120V input power
accidently, the ballast power will
decrease to 50% of the set power
automatically. Turn off the ballast and
replace it with correct 240V input
power. If the voltage is a bit lower
than 240V, the LED will blink and
the ballast keeps running with set
wattage.
One rapid yellow flash

high (max. 115°C/239°F)
There is temperature sensor in the
PCB of the ballast. If it senses the
internal ballast temperature reaches
1100C, the LED will start to blink. The
ballast power will decrease to 50%
of the set power automatically. Users
