Symptom Possible Cause Corrective Action
Lamp will not start •Incorrect lamp or ballast •Compare ballast/lamp label against lamp type.
or starts slowly •Lamp is loose in socket •Back lamp out and retighten.
•Incorrect or loose wiring •Power off, check for proper connections. Connect fixture lead marked for proper voltage
to voltage supply lead. Connect white or lead marked COM to neutral supply.
•Lamp at or near end of life •Replace with new lamp. HPS lamp will cycle on and off as lamp reaches end of life. MH lamp
will suffer severe color change as lamp nears end of life.
•Line or ballast output •Check line voltage at fixture. Check open circuit voltage.
•Faulty ballast •Check circuit continuity.
•Starter circuit failed •Replace lamp with known good lamp.
•Ambient temperature too low •Check ballast rating against existing environmental conditions.
Cycling (lamp turns •Lamp at end of life •Replace with new lamp.
on and off) •Incorrect lamp or ballast •Compare fixture and lamp label for matching wattage and
source. Compare fixture and system voltage rating.
•Ballast output voltage low •Check line voltage at the fixture. Check open circuit voltage.
•Incorrect lamp operating •Check lamp specifications for proper operating position.
position (Metal Halide)
•Line voltage variations
•Check incoming voltage with recording voltmeter (if this is the problem, check other
equipment on same circuit).
Low Lamp Output •Lamp end of life •Replace with new lamp.
•Line voltage or ballast •Check line voltage at fixture. Check open circuit voltage.
output voltage
•Incorrect lamp or ballast
•Compare fixture and lamp label for matching wattage and source. Compare fixture and
system voltage rating.
Short Lamp Life •Incorrect lamp or ballast •Compare fixture and lamp label for matching wattage and
source. Compare fixture and system voltage rating.
•Line voltage or ballast output •Check line voltage at the fixture. Check open circuit voltage
voltage too low
•Lamp operates less than 10 hrs.
•Rated lamp life is based on 10 hours of operation per start. General rule for expected lamp
life is 50% reduction in burn time per start results in 25% reduction in lamp life.
