Troubleshooting Guide
Maintenance
• The fluorescent lamps provided with the fixtures are rated for up to 10,000 hours. However, as with all
lamps, there will be some drop-off in intensity as they approach their rated life. A conservative user may
want to re-lamp at 75-80% of the rated life.
Brightline
recommends that as lamp intensity begins to
drop off, or when the life expectancy is reached, all lamps in a room be replaced as a group.
• The lamps provided with your
Brightline
fixture have been selected to provide the correct operating
parameters for your video system. All lamps should be replaced with those having an identical model
number and manufacturer. After relamping, it may be necessary to perform a new white-balance on your
camera(s) after re-lamping. Contact your
Brightline
dealer or representative if you need assistance
in purchasing replacement lamps.
• Dispose of used fluorescent lamps in conformance with local regulations or by participating in
Brightline’s
lamp-recycling program.
• For optimal fixture performance, it is necessary to keep the lamps and lenses clean. Use a dry, non-abrasive
cloth to remove dust. Avoid the use of materials that might scratch the lenses.
