Enhance your indoor garden area with the Hydrofarm Phantom digital ballast. The Phantom offers the only vertical operation in the industry, saving space, while packing the punch of the most effective power-factor on the market, a high .98 out of 1. The Phantom operates below the radar, with its complete silence and low energy use making it almost fade into the background and letting your plants take center stage.

Find a Phantom that fits your needs with 250, 400, 600, 750, and 1000 watt options available.

Several versions of the Phantom also offer LED-indicator dimming.

The Phantom's got your back with built-in protection. You'll find the system's reset buttons, which work as thermal cutoffs, vital in cases of an overheating situation. All Phantom units also provide built-in hot-restrike programming, never blow a bulb or burn your fingers again. Even with this safeguard, Phantom can still boast of the highest light output for maximum plant growth and unsurpassed reliability in the industry.
