electronic ballast Feature: * Aluminium alloy housing with surface anodic oxidation process.. * IC and CMOS chip controled hi-tech electronic ballast. * Suitable work voltage is 90 300V. * Suitable work temperture is -10 50. * Zero current on filament as it works,to extend the spanlife of filament. * Preheat filament function to extend tube life by times. * High power factor (PF>0.99),to ensure energy saver and increase efficency of power system transmitting. * Low Harmonic Distortion (THD<10%),to lower its effect on the electronicity network.. * Low Crest factor (CF≤1.5),to keep the current more steady. * Zero current make the electronic ballast reducing itself wastage to extend its lifespan. * Longer lifespan is over 5years,even to 8-10years.
