Remote (detached) use of reflectors with Phantom ballasts from the 40 Series line should only be done with Hydrofarm brand reflectors having a built-in 15′ cord. The use of additional lamp extension cords, plug adapters, and non-Hydrofarm reflectors may not work with Phantom ballasts in remote applications.
