    A: The Phantom 315W Ceramic Metal Halide CMH Reflector does not come with a ballast. The ballast must be purchased separately. Happy growing!
  • 1
    A: The Phantom 315w Ceramic Metal Halide (CMH) reflector coverage area is about 4' x 4' during vegetative growth, and 3' x 3' for flowering phases. This is if this is your sole/primary light source. This light could even be used in a space as small as 2' x 2' comfortably. The 4' x 4' and 3' x 3' are more of a maximum footprint. Often these CMH lamps are used in between larger more powerful lights to give a better well-rounded spectrum since CMH's have such a wider spectral offering than traditional HPS and MH lamps.

  • The lamp may require 10‒30 minutes cooling time before restarting.
  • After you plug in and power on the ballast, the lamp may require several minutes to reach its full brightness.
  • Be aware that in the event of a momentary power interruption, the lamp will not restart immediately.
  • Some variation in the color of light emitted by the lamp is not unusual, especially in the first 100 hours of operation.
  • Never pull the cord to unplug the reflector; pull the plug only.
  • Avoid scratching the lamp, subjecting it to undue pressure, or getting it wet when it is hot—these actions may cause the lamp to break.
  • In the event of lamp breakage, immediately unplug the reflector to prevent exposure to ultraviolet energy, which may be harmful to eyes and skin.
  • Keep room temperature below 95°F, with adequate air circulation provided by oscillation fans in the growing area.
  • Please take care to consider proximity to plants when installing your fixture. Closer proximities will give greater intensity, but they will also reduce the effective coverage footprint.
  • Always use a heavy-duty three-pronged grounded timer, rated for at least 15 amps.

    Must Have For Happy Plants Review by Rkuck67
    Overall Rating
    First off let me say that the Phantom 315W Ceramic Metal Halide Reflector is by far, the best lighting option that I found after months of research. Both from a cost perspective and effective lighting standpoint this unit is the most awesome piece of equipment I have in my grow room, hands down.

    Okay, now for the nuts and bolts. Right out of the box, the Phantom is leaps and bounds a more well-made product than most of the other reflectors out there. It feels solid, well put together, and gives me the confidence that when I hang it up it's going to stay up, and not come crashing down on top of my beauties. The hanging clips swivel so that when you hang it it remains level which ensures that the light coming down is as even and will spread as it can be.

    At first I wasn't too sure about a vertical light. It just seemed as if there would be a dead spot somewhere below the light fixture. However, as far as I can tell this is as strong or stronger a light than any horizontal out there. After seeing it in action at my local grow store and feeling the very small amount of heat put out by this monster, I was still very impressed when I had it hanging in my own grow box. I mean you can literally put your hand right beneath this light and leave it there indefinitely and all you're going to feel is a very slight warmth. The ceramic metal halide bulb coupled with this amazing reflector is just a far superior product and I am 100% glad I pulled the trigger on it. My plants could not be happier, and even after just a couple weeks, I can tell the difference in their overall appearance, growth, and color. They are really taking off!

    So if you're looking for a new grow light or one to supplement your current setup, don't hesitate and quickly add this to your cart. You will not be disappointed. (Posted on 2/20/2017)
