Specification :

A)Startup Time: can reach 20% of the standard brightness within 1 second; can reach 90% of the standard brightness within 4 seconds ;
B)•Auto Cut-off: once there is a short circuit or open circuit, the ballast will stop working automatically ;
C) Protection Voltage: when the voltage exceed 18V, the ballast will stop working automatically, and make the output power below 45W to protect the ballast and bulb from damage. When the voltage is 8V, the ballast still can work normally, but when the voltage is below 8V, the ballast will stop to protect the ballast from damage ;
D) Reverse Polarity Protection: the ballast will stop working automatically when a reverse polarity happens ;
•E) Open-Circuit Switching>110,000 times testing in 0.5Hz
•F) Lighting Switching>210,000 times testing in 0.5Hz
•G) OEM diviersified ballast aucustomers order,such as 75W,120W,220W ballast in house and industry purpose.
