Installing the reflector and lamp
The coverage of your reflector depends on the light levels you want to achieve and the output of your lamp. With a
1000W 2000 - 2100 μmol s-1 lamp you can cover an area of 2 square meters (~22 square feet) with 900-1000 μmol
s-1 m-2 average. The reflector has a rectangular (wide) throw.
Keep your reflector away from combustible materials at all sides. Use reliable mounting materials and keep
your lamp cords away from the direct heat from the lamp and the reflectors. Make sure that the lamp cord does
not touch any hot parts of the reflector. Make sure the lamp is clean and inserted correctly. Use light hangers
or small chains to hang the reflectors at the correct height.
The recommended minimum distance to a crop:
750W lamp – 70 cm
1000W lamp – 90 cm
Lamp replacement
Always install the lamp before connecting your ballast to mains.
Always be sure to connect your lamp cord to the ballast before switching it on
When changing the lamp always disconnect the ballast from mains by removing the mains plug. Let the
lamp and reflector cool down for 20 minutes before changing as they can be very hot. When replacing a
defect lamp without disconnecting mains from an electronic ballast the new lamp may not start:
disconnecting the power will in many cases reset the electronic ballast safety circuitry.
Only use lamps in this fixture that have been rated safe for open fixture use.
Only relamp with lamps that are suitable for an open reflector. When using MH lamps, use self shielding lamps.
Let the reflector and lamp cool down and disconnect the ballast from mains when replacing a lamp. Use
gloves to keep the lamp clean, as the lamp surface becomes very hot. Screw in the lamp firm, but not to tight to
prevent breaking the lamp. Always check the center contact for damage when replacing a lamp.
To take out a lamp:
DISCONNECT THE BALLAST FIRST
Open the lamp holders by sliding them outward. The lamp is now held
by a metal spring at each side, though it is recommended to hold the
lamp while opening the lamp holders to prevent the lamp from falling.
Take the lamp out
