Guidance on Essential Maintenance for Fluorescent Light Fittings
The Lighting Council New Zealand recommends regular maintenance for the safe and efficient operation of fluorescent
light fittings common in commercial properties. New guidelines issued to this end are designed to ensure efficient
operation and reduce the risk of failure.
“All electrical technology generates heat, creating a fire risk if not properly maintained. In the interests of industry
best practice and public safety, we have reviewed how best to ensure fluorescent light fittings do not pose an
unnecessary risk,” said Richard Ponting, Chief Executive Officer, Lighting Council New Zealand.
Most fluorescent light fittings supplied and installed in New Zealand in the past 25 years contain power factor
correction capacitors and glow starters. Regular maintenance, checking and replacement of these components is essential
to ensure they operate safely and efficiently. Lack of regular maintenance or a failure to replace aged or damaged
components, particularly capacitors, reduces efficiency and performance and may create a risk of failure.
It is recommended that commercial property owners take the following advice to appropriately maintain their fluorescent
light fittings:
• At least every three years and whenever fluorescent tubes are replaced, fluorescent light fittings need to be checked
to ensure that there are no signs of ageing or damage in any components such as capacitors, ballasts, lamp holders and
starters.
• Any capacitors, ballasts, lamp holders or starters showing signs of ageing should be replaced immediately.
• Capacitors have a life span of between five to ten years. They must be replaced at or prior to 10 years. Ensure that
the replacement capacitors and ballasts meet the lighting manufacturer’s specification for the lamp in question.
• Maintain a maintenance log and/or record on the component itself the dates it has been checked and the dates any
components have been replaced.
• Avoid the application of unnecessary external force when carrying out checks/maintenance. Do not use any components
that are dropped or damaged.
• Any light fittings that are subject to permanent or frequent external heat will require more regular checking and
maintenance. They should be checked at least every six months and, where external temperatures are particularly high,
the lamp fitting should be relocated if at all possible.
“Responsible commercial property owners/operators will already have robust plans in place for regular, routine
maintenance. While regular maintenance of fluorescent light fittings does require a commitment from property owners,
this should be viewed in the context of improved performance and risk management,” said Mr. Ponting.
