Normal End of Life of Bulbs:

Bulb cycles on and off.
Blackening at ends of arc tube.
Brownish tinge on outer glass envelope.

If you discover a fixture not working, disconnect power immediately, thus avoiding causing damage to internal components.

Checking Power Supply:

• Check power switches
• Check Circuit breakers/fuses
• Check photo/timer controls
• Correct line voltage indicated on fixture label
• Check your computer settings if controlled by computer

Disconnect power before opening a fixture or replacing a bulb.

When ordering replacement parts, please indicate the part numbers of the defective parts.

Cleaning Your Fixture

It is recommended that you clean your bulbs and reflectors at least once a year.

Turn off the power and let the bulb cool down first.

Use lukewarm water mixed with household detergent and a soft cloth. Make sure that the bulb is clean and dry before reinserting it back in the fixture.

If you experience any other problems, please feel free to contact us.
