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
