Proper maintenance of any lighting systems is essential to maintain the levels of illumination necessary for productivity, merchandising, visual comfort, safety and security. Employing simple maintenance procedures and timely attention to small problems such as replacing burned-out lamps will keep most major repairs minor. If an individual component fails and is allowed to remain in the lighting system, costly damage to other components can result.
CAUTION! Troubleshooting and maintenance of lighting fixtures presents possible exposure to hazardous voltages. Always employ qualified personnel for all troubleshooting or maintenance procedures. When replacing fixture components, be sure that all replacements used are installed in compliance with the National Electrical Code as well as any applicable local codes and ordinances.
Fluorescent Lighting Inspection
To achieve extended ballast life, and the greatest efficiency from fluorescent lighting fixtures overall, periodically inspect for signs of trouble. The significance and correction of these conditions can vary with each lamp type and ballast used. It may be time for maintenance if you observe any of the following:
- Lamps Inoperative
- Lamps slow to start
- Lamps are dim
- Lamps heavily discolored
- Lamps cycling ON and OFF
Fluorescent Lighting Maintenance
The following general maintenance procedures are specifically for fluorescent lamp and ballast type fixtures only. By following these maintenance suggestions, both the ballast and bulbs will last longer, and the ballast will be more trouble-free throughout it’s usable life. Only perform maintenance when the entire circuit being serviced is de-energized.
- Lamps must be replaced when they reach 70%-80% of their rated life. If bulbs become heavily blackened at the ends before this time, go ahead and replace them.
- Before purchasing replacement lamps check to insure they are compatible with the fixture. You can find the supported bulb type and wattage listed on the label of the installed ballast. Some common lamp types are T12, T8, and T5. Always check the ballast for the bulb type before you purchase and install new bulbs. Don’t forget to note the wattage that the ballast supports, and whether it requires a high output or rapid start bulb.
- Make sure that lamps are properly seated in the sockets.
- Clean lamps, reflectors, and lenses periodically as the accumulation of dust and debris, combined with highly humid conditions will impede starting and proper operation of the lamps.
