Description and Overview 

The Phantom CMh 315W ballast is a remotely operated, low frequency, square-wave digital ballast designed specifically for the 315W high intensity ceramic halide lamp, which can be used with equal effectiveness for both vegetative and flowering growth. It features internal RF shielding, multi-aspect protection circuitry, versatile 120/208/240V input voltage, and patented lamp depreciation control.

Like all ballasts in the Phantom family, the CMh 315 ballast is silent, reliable, and energy-efficient. It can easily be wall-mounted near the reflector, and can be mounted up to fifty feet away from the reflector using our optional lamp cord extensions. Includes an 8' 120V power cord, operating instructions, and a three-year warranty.

Phantom 315W features:

  • Low Frequency, square wave technology provides much greater current stability and consistency in output levels, as well as low acoustic resonance.
  • Up to 65' lamp striking distance: Separate the ballast from your reflector by up to 65' of distance if necessary. (optional lamp cord extensions may be needed)
  • Multi-volt capability: Can be run at either 120V or 240V.
  • Multi-aspect Protection Circuitry: Includes short circuit protection, open circuit protection, overvoltage protection, under voltage protection, overcurrent protection, hot lamp startup protection, lightning protection, overheat protection, lamp failure protection, and lamp life warning.
  • Patented output control maintains maximum PAR value over lamp life.



Phantom brand of ballasts and reflectors represents the very best available in indoor horticultural lighting equipment. The Phantom ballast family includes both traditional and double-ended models. The original Phantom and Phantom II ballasts led the way, offering adjustable output control (dimming), silent operation and precise microprocessor control. These core features formed the basis for the innovation that led to our latest models of Phantom double-ended (DE) ballasts.

Phantom brand reflectors are available in two models: a traditional single-ended (E39) socket type (PHR6010), and the DE model (PHR6020). Both are air-cooled reflectors and offer latched, sealing lens systems, and both models feature premium, 99.85% pure European hammertone aluminum interiors that provide 95% reflectivity. A pre-galvanized powder coated body for durability, strength and longevity is another feature common to both of these reflectors.

Full Commercial DE lighting systems are also available, and they feature the winning combination of Phantom ballasts, reflectors and Agrosun DE lamps. These DE systems embody the innovative double-ended technology, which uniformly delivers optimum PAR value over a broad footprint.
