Troubleshooting
Before requesting service on your Verilux ® lamp, please read
the following:
• Make sure all power connectors, cords and plugs are inserted fully
and securely.
• Be sure the bulb is securely seated into the socket (see page 8).
• Make sure there is power to the wall outlet or try another outlet.
WARNING: Do not block vents on ballast. Vents are necessary for proper
function of the ballast; blocking them may cause overheating of the
ballast and increase risk of fire.

Insert plug securely into wall outlet.
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.
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.
Be sure the bulb is securely seated into the socket, repeat the bulb
installation process. CAUTION: DISCONNECT LAMP FROM OUTLET
PRIOR TO REPEATING THE BULB INSTALLATION PROCESS.
