REPLACING THE LIGHTS
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 dif-
fuser frame, pull forward and drop into place.
Push up and back
over notch in back of
cabinet, then let front
drop down
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 29.
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.
