The Sunmaster Hobby 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 Hobby 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 Hobby 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.
The Sunmaster Hobby 600w ballast comes with a 3 year guarantee.
Please note the Sunmaster FX is no longer in production, there wasn't enough difference in the feature set between the FX and the Hobby to justify making both models.
The short answer is yes. Both Sunmaster HPS & Metal Halide grow lamps are designed to be able to cope with small surges in power output beyond what they claim. However, running your 600W lamp at 660W with the power boost option on this ballast will reduce its lifespan.Will running my lamp on power boost mode produce better yields?
It depends. If your are optimising your grow room and looking to run the most productive system possible, then adding 10% more power into the lamp will probably help yields. If you just have a few plants under lights that you chuck some water on once a day or so, then you probably won't notice any difference.Does this ballast interfere with electrical equipment?
No. The Sunmaster Hobby is fully RF shielded to eliminate interference with other electrical goods.Can I use this ballast with any reflector?
The Sunmaster Hobby comes with an IEC connection which is the standard fitting for practically all reflectors on the market.Is it really silent running?
Yes. Most digital ballasts are designed to run silently and the Sunmaster Hobby 600W digital ballast is no exception to that rule.Will I save money using a digital ballast instead of an analog one?
Yes, but only a very small amount. Digital ballast put out less heat than their analog counterparts and are slightly more efficient, but the emphasis here is on "slightly". Don’t expect to see any dramatic change in your running costs, but overall, digital ballasts are marginally cheaper to run.
