High Pressure Sodium along with some Metal Halide lamps need an
external starting device commonly known as an ignitor. This
device provides a high voltage pulse that is needed to initiate an
arc within the lamp.
ignitors ability to provide a reliable power pulse to a H.I.D.
lamp is influenced by many factors. Compatibility between
ballasts and ignitors, wire size and supply condition, and a
number of other variables which differ with individual
applications all affect the operation of any starting device.
from USTA should be used in order to obtain maximal life
expectancy. The key to longevity is the special design that
match each particular lamp/ballast along with the manufacturing
precision that USTA provides.
safety reasons, the temperature of the ignitor
housing should not exceed 105 degrees Celsius under normal
