REPLACING THE LIGHTS

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.

Occasionally you may need to replace a light bulb.
It is a simple process, similar to changing the bulb
on a fish tank 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 consid-
ered high use and the efficiency of the
bulbs will reduce approximately 10% after 20,000
hours. Bulbs should be replaced every 18-24
months to ensure best performance.
