This item features a hot restrike function that protects the lamp and the ballast. Through this, the ballast reignites the light once it has cooled down. In cases of power interruptions or failed ignitions, the ballast spends a minute before attempting to restart the bulbs. Your lamps will then learn from the sequence of events based on the above mentioned situations.

The only downside I have seen in this product is its limited capability to light up bulbs as its receptacles only complement those that are suggested by Sun System only.
  • Close to silent operation at <10% harmonic distortion
  • Has an internal circuit breaker to prevent splatter of unusual currents
  • Perfect for 1000w DE and 1100w Hyper Arc SE bulbs
  • Hot restrike function for safe reignition after cool down

If you want a ballast and a lamp that makes no complements other than the ones they assign with, then this is a perfect combination for you. I know this is safe, silent, and reliable

What to Look for When Buying Digital Ballasts


Different 1000 watt digital ballast reviews suggest practices when choosing a ballast. If you are looking for it but unsure of the characteristics to look at, consider the following important notes that may lead you to the best one:

  • Bulb safety – To preserve your bulbs, select the ballast with ignition voltage control and regulate current flow.
  • Versatility – Your ballast must be able to withstand different conditions and locations. It also has to work with either MH or HPS bulbs, DE and SE ones. And it’s expected to run bulbs of different wattage.
  • Durability – A quality ballast shows little to zero effect on your lamps’ performance in cases of voltage fluctuations. You have to consider the kind of materials used for its casing, and even its internals.
  • Dimming – Crops do not grow on the same level of sunlight. So, your ballast has to have different dimming levels for you to switch on whenever necessary.
  • RFI Protection – Wire shielding is essential for your ballast to protect electronic devices and radios from signals within frequencies coming from it.
  • Temperature – Ballasts get hot, but not too hot that you can’t touch it. You need to pick the one that causes no overheating, otherwise, your greenhouse will burn out, or your plants will lose excessive amounts of
  • Noise – Little sounds coming off its cooling fan is bearable, but not the one that becomes annoying.

What is the Best 1000w Digital Ballast

The best 1000w digital ballast I can confidently recommend is the SolisTek Matrix LCD DE 1000W Dimmable Digital Ballast. Given its advanced technologies that ensure a secured connection and ignition, cycled light-ups, and synchronized ballast action, I am sure everything you need with ballasts is in this package.

How Many Amps Does a 1000 Watt Ballast Use

Ballasts use different levels of electrical current depending on the voltage and the lamp’s wattage. For 1000w ballasts, you need to have 8.33A at 120V and 4.17A at 240V electromotive force. Be sure to keep these figures in proportion or consult an expert to avoid lapses with your artificial light system.

Can You Use a 600-Watt Bulb In a 1000 Watt Ballast

People dim down their ballast for several reasons, like cutting costs and adjusting light levels based on their crops’ needs. You can run a 600w bulb in the best 1000w ballast, granting that your dim level points at 600w as well. Running a bulb and a ballast of unequal wattages is not without effect. Chances are, you might shorten the life of either your bulb, your ballast, or both, or you might cause electrical fluctuations within your area. Yes, it is possible, but not advised.


With lighting being a significant factor in indoor gardens, we should never neglect to observe the best practices. Otherwise, our pot babies will all wither and die. Selecting the best 1000 watt ballast can get you confusing over a lot of choices in the market. So, always look after the growth of your plants and the safety of your electricals in general.
