Occasionally you may need to replace a light bulb. It is a simple process, similar to changing the bulb on an aquarium hood.
For part number, see the list on page 26.
NOTE: T5 growing lights running at the default
time of 18 hours per day is considered high use
and the efficiency of the bulbs will reduce approx-
imately 10% after 20,000 hours. Bulbs should be
replaced every 18-24 months to ensure best performance.
Remove the diffuser shield by pushing it up with both
hands, then pushing it back far enough for the front to
drop down, and then pull out.
Grab each end of the bulb (metal ends of tube), rotate
clockwise until you can pull the bulb out.
Insert the ends of the new bulb into the black ends of the
ballast, then turn counter-clockwise until the bulb snaps
into place.
Replace the shield by lifting it up and back over the notch
in the back of the cabinet, push up the front until it clears
the front of the diffuser frame, pull forward and drop into
place.
