Your lamp is made from high-quality materials that will last for many years with
minimum care. You may want to periodically clean the lamp using a mild non-
abrasive cleaner and soft cloth. When cleaning, make sure you have turned off
and unplugged the unit and allowed sufficient time for the unit to cool.
WARNING:
To prevent risk of shock or personal injury when cleaning
lamp, make sure you have turned off and unplugged the lamp and allowed
sufficient time for the bulb to cool.
Clean only with a soft dry cloth – do not use solvents or
cleaners containing abrasives or ammonia.
After cleaning the lamp, wipe away all moisture and let the
lamp dry completely before restoring power.
Care and Cleaning
Before requesting service on your Verilux lamp, please:
• Make sure all power connectors, cords and plugs are inserted fully and securely.
• Be sure the bulb is securely seated in the socket. (See pages 8 and 9.)
• Make sure there is power to the wall outlet, or try another outlet – one that is not
connected to a dimmer.

Check bulb for blackening/darkening at bottom of spiral where it joins the
base (an indicator of bulb life) and replace bulb.
Be sure the bulb is securely seated into socket. Repeat the bulb
installation process.
DISCONNECT LAMP FROM OUTLET
PRIOR TO REPEATING THE BULB INSTALLATION PROCESS.
Sometimes when a new bulb is turned on for the first time the tube will
darken, but this will fade after a few minutes.
With older bulbs, darkening of the tube indicates end of bulb life. (This
doesn’t affect operation except to reduce the amount of light available
since the phosphor in that area has become inactive.) Bulb replacement
is recommended.
Insert plug securely into wall outlet.
Connect lamp plug only to wall outlet without dimmer switch.
Light won’t tilt
Are the thumb screws
too tight?
Loosen the two blue thumb screws on the back of the unit, adjust the lamp
to the desired angle and re-tighten the two thumb screws.
Be sure the bulb is securely seated into the socket. Repeat the bulb
installation process. DISCONNECT LAMP FROM OUTLET
PRIOR TO REPEATING THE BULB INSTALLATION PROCESS.
