Things to Consider When Buying Best Digital Ballasts


When buying a ballast, you should consider its dimming capabilities. Dimming enables you to save power sometimes by turning your light at a lower voltage. The best ballast can allow up to 50% dimming of power whereas there are more advanced ballasts that can adjust even lower than that. A digital ballast does the dimming digitally while other ballasts do it manually. So depending on the rate at which you want to save power you choose the best dimmer.

Bulb Protection

Apart from dimming, you may also consider a ballast that can protect your bulbs from burning out. The best ballasts have their own added bulb protection features. These features may include line quality and ignition voltage control


Besides dimming and bulb protection, you may think of how long you plan to use the ballast. In short, it's durability. Well, for a ballast to be durable it has to be of the best quality. How you have done your electrical connections also matter in this case. You don't want to get a ballast that will be defective in a short time. Note that, high-quality ballast last even a decade if you have good electrical connections as like best 1000w digital ballast.


Depending on the brand, some heaters come with added accompaniments. Why would you spend extra on a shower or a house when you can get that all at a go? Some useful water heaters accompaniments include a hose, a temperature gauge, a shower head a dual function heating system such as a gas burner.


To stay safe from being tracked down just because your ballast had a radio frequency mix up, you need to consider selecting a ballast that has the best radio frequency shielding. If it is not well covered, depending on how they work, they create radio frequency interference. Other electronic devices you may have around may begin to shutter and you may be sued for that.


Another thing you may consider is the flexibility of your ballast. A flexible ballast will simplify your gardening. This means you will be able to use it under several situations like lighting a number of bulbs, using different bulbs that utilize different voltages, supporting double end bulbs and boosting the power output of your garden bulbs.

Temperature Control

Having your entire hydroponics equipment running together with the lit bulbs, it means your chamber will begin to rise in temperature. High temperatures could be good for Cold months but somehow it affects the transpiration of your plants by increasing it. If you are planning to buy a digital ballast, find one that when it heats it doesn't become hot because it will be challenging to switch off. Besides your plants will lose so much water.


A good ballast is quiet. Only the cooling fan may make some noise but the best ballast produces 100% no noise. Since most ballasts are designed to be super silent, this consideration may not give you a hard time. If it makes noise, it has lost its radio frequency, has some loose screws or any other problem.

Frequently Asked Questions

Q: What is the difference between digital ballast and electronic ballast?

A:  Digital ballasts have higher output and provide better spectral output compared to electronic ballasts which give 30% less light. Digital ballasts also have adjustable wattage and can allow you to use power at different wattages, unlike electronic ballast. Digital ballasts use 3-4 % less energy compared to electronic ballasts.

Q: How long does digital ballast last?

A: According to Certified Ballast Manufacturers Association the average digital ballast lasts about 20 years if regularly used in contrast to magnetic ballasts which will last about 75,000 hours or 12 to 15 years. It is advised to change your ballasts before this time in order to increase its productivity.

Q: Can a digital ballast catch fire?

A: Yes, ballasts can catch fire when there is poor electrical contact. Electrical energy can cause fire when there are voltage drops across poor contact.

Q: When should I use a boost on digital ballast?

A: You can use it in the last couple of weeks before harvesting to fatten the buds up more or to boost a bulb back close to its original light output and squeeze another life out of it.
