Lamp Replacement
Fluorescent lamps typically have an average rated life of 20,000 hours. Under normal operating
conditions, group relamping is recommended every 48 to 52 months. Some lamp failure will occur before
this recommended interval and single lamp replacement should be considered where necessary. Lamps
are removed by ¼ turn. Use care when removing or installing lamps and do not work above others.
Ballast Replacement
Before replacing ballasts, first try replacing the lamps. If that fails to solve the problem, then the
appropriate ballast should be replaced.
Before attempting to verify and replace a ballast, the affected luminarie module must be taken off line.
To isolate power from the unit, disconnect all circuits.
Most fluorescent luminaires ship with factory installed disconnects at each ballast location. Although the
ballast disconnect provides an additional safeguard when servicing fluorescent lamp luminaires, it does
NOT replace the need for turning off power to the circuit.
Once the ballast is replaced, ensure all fasteners are reattached and all applicable plugs are solidly
reconnected – especially the grounding wire.
Note:
A ballast replacement should only be performed by a qualified technician.
Ballast warranties are offered by the ballast manufacturer and not by Lithonia. Contact Lithonia for a
ballast breakout by project if required or for ballast manufacturer service information. Ballast information
can also be found on the ballast label.
Inspection
It is recommended that lenses and lamp holders should be periodically inspected for cracks or damage
from exposure to corrosive airborne chemicals and/or to impact damage. Any damaged component
should be replaced.
Cleaning Instructions
Regular cleaning of light fixtures is essential for optimal lighting performance.
Exterior Surfaces
It is recommended that all surfaces be cleaned regularly to remove accumulated dust and dirt. Best results
are obtained by wiping with a damp cotton cloth.
Internal Reflector Systems
All luminaire reflectors should be dusted periodically to ensure optimal lighting performance—possibly
during a systematic relamping operation. Any cleaning of reflectors should be carried out with care so as
not to damage the materials used to optimize performance.
The specular aluminum reflector may be cleaned after lamps are removed and normal safety precautions
are taken to avoid shock and electrocution, including turning off power to the light fixture.
The reflector can be cleaned with a mild, fast-drying, non-alkaline solution and soft cotton cloth. Examples
of acceptable cleaners include a 2% solution of liquid dish soap to water or a 70% solution of ethyl or
