Founded by a veteran
returning home after World War II, Keystone has been in business in
Pennsylvania for 70 years and stands behind this reliable product with a
five-year warranty, with no questions asked. This ballast is program start,
which means it’s ideal for applications in which lights will be turned on and
off frequently. Because program-start ballasts warm up the cathodes, lamps last
longer compared to lamps controlled by ballasts using instant start.
