The Sunmaster FX 600W digital ballast is a premium quality digital ballast that features a 4-way dimmer switch to give you complete control over the power output to your plants.
The ballast will power 250W, 400W or 600W HPS or Metal Halide bulbs and includes a boost mode that increases output to 660W which is really beneficial during the flowering/fruiting phase. Be sure to pair the correct lamp to the output selected, so don’t be tempted to run a 400W lamp at 250W for example. This will save energy, but is a pretty pointless exercise as your plants will not receive the full PAR (usable light) range.
Another highlight of the ballast is the inclusion of the “Intelligent Ignition” feature. Plug more than one Sunmaster FX ballast into the same power supply, flick the power on and the ballasts will cleverly start up one at a time to prevent an electrical surge from tripping the circuit breakers.
As with other digital ballasts, the Sunmaster FX will extend the life of your lamps by protecting the bulb from power surges and eliminating flicker. It also includes RF shielding so will not interfere with other electrical equipment in your home.
