How to Turn Your PARsource Attached Fixture into a Remote System

PARsource HID systems are designed with flexibility so each unit can be utilized as an attached or remote fixture. An attached fixture is defined as a system with the reflector attached to the ballast. See Figure A for an example of an attached fixture.

A remote fixture is defined as a system with the reflector and lamp located inside the greenhouse while the ballast is located either inside or outside the greenhouse, within a specified radius from the reflector. See Figure B for an example of remotely placed reflectors.

Most greenhouse lighting projects are sold as attached fixtures. If a grower decides to take advantage of the benefits of a remote system, this can easily be done in a few steps with their attached ballasts.

  1. Unplug the reflector cord from the ballast and reflector. (Diagram A)
  2. Remove the reflector safety lock and slide the reflector upward to detach the reflector from the ballast plate. (Diagram B)
  3. Hang the reflector from a greenhouse framing member above the crop. (Diagram C)
  4. Move the ballast to its new remote position near a power source. (Diagram D)
  5. Purchase and install the intermediate extension reflector cord between the ballast and reflector. The extension cords come in three lengths: 5, 15 & 25 feet. (Diagrams E & F)

NOTE: You should avoid using cords that are longer than you require as unneccesarily long cords must be coiled, which can cause performance issues with the  ballast.

Once this is completed, you have converted your attached fixture into a remote system.
