What’s Included with the Base System:

Digital Greenhouse 400w Digital Ballast features patented “soft-start” technology which increases lamp life and stops voltage spikes on your power meter. The soft-start technology allows for 50% less power consumption during lamp startup. It is also virtually silent, no noise or hum. The ballast is totally sealed, which protects the unit from dust and dirt, ensuring a lifetime of trouble-free operation.

Digital Greenhouse ballasts operate at 20,000Hz, which allows the lamp to operate more efficiently, produce more usable light for plants and last longer. Lamp lumen loss is minimized allowing for a brighter system over time and extending usable lamp life. Multi-volt capability also allows the ballast to automatically adjust to any input voltage from 90 volts up to 260 volts. It comes equipped with a 10’ grounded power cord, and plugs into a standard 120v household power outlet.

Digital Greenhouse ballasts are now UL listed! What does this mean? This means that Digital Greenhouse ballasts are now certified for safety by Underwriter Laboratories, the worlds leading electrical product safety organization. Check the other brands. Are they listed? Probably not… Demand safety, demand Digital Greenhouse!

As of January 1st, 2010, the Digital Greenhouse ballasts is covered by a 5-year warranty (3 years complete, 2 years pro-rated).
