Verification
Prolonged operation (a matter of weeks) with a lamp that does not start will eventually cause ballast to fail. The best practice is to replace failed lamps to
prolong ballast life. In situations where lamp maintenance is not practical, ask about incorporating Howard's Starter Stopper, to reduce the stress on the
ballast when the lamp reaches end of life and fails to start.
