What is a Digital Ballast?

A digital ballast is basically a piece of lighting equipment. It regulates the voltage which the high-intensity discharge light or the compact fluorescent lighting receives. This way, it prevents those electronics from overheating and possibly exploding.

Benefits Of Using Digital Ballasts

Energy Efficiency

These digital ballasts save lots of energy. As a matter of fact, most models save up to 25% more energy which leads to a reduction in the utility bills in a typical year. This is not to mention that it yields greater returns on average.


With the typical digital ballast, it is possible for you to carry out numerous closely-related chores. These include the encouragements of the growths of plants and the lighting of the indoor growing areas, among others.

Compact Sizes

Generally speaking, these equipment are compact in size. As such, they are easier to transport out and about the desired area with minimal hassles. You will, therefore, find them quite handy when you are constantly on the go!

Increased Wattage Options

Quite a number of them also allow you to select the power output that is relevant to your cause. Such power negates the need to waste unnecessary levels of electrical energy which also cuts down the utility bills. At the same time, you get to obtain the outcomes that relate to your specific need.

Seamless Installations

Lastly, most digital ballasts are easier to install. They require almost no specialized tool for the job and also call for limited expertise. Regardless of your skill and experience, you will find this equipment great and awesome for your circumstance.

Types Of Ballasts

There are three basic types of ballasts. These are explained below:

a) Magnetic Ballast

These kinds of ballasts generally play the role of mopping out excessively high current levels after igniting a lamp. In so doing, they prevent the lamp from blowing out. They are more manual in nature and are hence not so reliable.

b) Electronic Ballast

The electronic ballast is installed in line with a load to limit the current in the circuit. It operates much like a transistor, only that its current level is higher which makes it better suited for larger kinds of circuits.

c) Digital Ballast

As stated above, the digital ballast performs the role of regulating the voltage which a typical high-intensity discharge or fluorescent compact light receives. This way, it prevents them from exploding and also stabilizes the current output.

How To Use Digital Ballasts

Install The Equipment

Needless to say, you have to start off by installing the equipment. Being a sensitive undertaking, you definitely have to invoke the assistance of a trained expert to help you out. Follow the manufacturer’s manual to the letter if you are confident of doing a good job.

Make The Necessary Wired Connections

After installing the system, proceed now to make the necessary wired connections. Connect the digital ballast to the lamps and other electrical components it is supposed to regulate. You will yet again need some expert assistance.

Set The Voltage Threshold

Now set the voltage and if possible, the current threshold. These are simply the upper limits of the voltage and the current you intend not to exceed. You will have to consult the manufacturer’s manual for guidance on how to go about this.

Test The System

Test the system. Switch on the light bulb and see how it responds. In case your digital ballast allows, vary the wattage progressively to note the response of the lamps. If you are dissatisfied with the outcomes, you might want to repeat the stages above.

You are now good to go! Just activate the system and enjoy its benefits.

Features To Look For In Your Digital Ballast

Size and Weight

Heat Output

This refers to the upper limit of the heat that the ballasts can manage to flow through the bulbs. A good ballast has to be able to attain the heat output levels which are relevant for your crop and desired applications.

Noise Levels

Some kinds of applications require no noise at all as they may happen in areas which are sensitive to the dangers of noise pollution. To be guaranteed zero noise levels, you have to settle for those ballasts which emit less noise on the whole.

Light Consistency

Lastly, you also want to consider the consistency of the light output. A good ballast has to be able to exude uniform light output to guarantee seamless reliability. At the same time, you also want one which is highly predictable and hence easier to control.

Frequently Asked Questions (FAQs)

Q1. How long do digital ballasts last?

Generally speaking, you should expect to use a typical digital ballast for around 2-3 years

Q2. Do digital ballasts use less or more electricity?

Most modern digital ballasts have features which minimize the loss of power. These are the adjustable wattage output and ability to switch in between various kinds of bulbs. As such, they use less electricity on the whole.

Q3. What are the main differences between magnetic and digital ballasts?

These two kinds of ballasts are similar in many regards. They, however, differ in their use and applicability. The magnetic ballasts are manual and cumbersome to engage when compared to their digital counterparts.

Q4. Do LED lights need a ballast?

NO, they are not! They are however engineered to pair and work for hand in hand with such devices.

Q5. Why do some lights need a ballast?

They play the role of regulating the levels of current and voltage to the start lamps. This way, they prevent those issues which would ordinarily arise out of the use of these devices.
