Use and Care Manual
Operating Instructions:
1.  Make sure the power supply cord and lamp lead are properly connected.
2.  Ensure the bulb is properly seated in the socket assembly. It should be tight, but not stressed.
3.  Always use a bulb centric to the highest output of the ballast (e.g. 1000w bulb/1000w ballast, 600w bulb/600w ballast, etc.)
4.  Conrm the ballast is not near any source of moisture or standing water.
5.  Check the sealed bearing fan to conrm it is free from any obstruction. This should be periodically checked to make sure it 
stays clear and clean.
6.  Plug the power supply cord into an appropriate power supply.
7.  After ignition, give your lamp a minimum of 30 seconds to reach full power.
8.  Always allow the bulb to cool before re-striking the ballast; we recommend 15 minutes.
9.  Ballast can be cleaned using a clean, dry towel. Should the ballast somehow become wet, turn o main power supply and 
unplug the unit before attending to it.
10.  Allow 10 seconds between power adjustments when using the Dimmer Switch. This will allow the ballast sucient time to 
gather electrical charge to increase wattage output.
Remember, safety rst. Although incredibly rewarding, indoor growing can present dangerous situations. Never allow standing 
water to be present, never hang a ballast from either the power or lamp cord, and always make sure your equipment is fastened 
safely and securely. Your ballast does not require any switches or re-wiring to change voltage or bulb spectrum. Simply turn o 
and unplug the unit and allow bulb to cool before changing cords or bulbs, respectively.
