Product Memo *Principle and features: *The function of ballast is to convert electrical current coming
from outside the light capsule to the right quantity of voltage and
amperage required to start the lamp safely and efficiently. *The ballast then stabilizes the current, regulating the pace of
electric flow after startup to ensure continued, safe operation.
Thus the working life of ballasts largely relies on the lamps. *The 4th generation ChangLong magnetic ballast, with no noise and
low temp rise, can use for 10 years under normal conditions.
