General Lighting: Ballasts: Electronic vs. Magnetic

There are two basic types of ballasts for fluorescent lamps. There are magnetic ballasts and electronic ballasts. There is a huge difference between the two.

One major matter is the design and components used. Magnetic ballasts are made of wire coiled so as to create a magnetic field. Electronic ballasts use electronic components.

Second, is the performance. Magnetic ballasts are not energy efficient They generate flicker noticeable in the fluorescent lamp. When the power switch is turn on, the fluorescent lamp will flicker for a few times before it can give a steady light. Electronic ballasts are energy efficient. Electronic ballasts do not generate flicker. They provide a rapid start for the fluorescent lamp. When the power switch is turned on, the fluorescent lamp lights up instantly (actually there is a very short delay that is not noticeable by the human eye).

One thing that gives a first impression about the electronic ballast is that there is no need for another component, the fluorescent lamp starter. In fact, the electronic ballast eliminates the need for the fluorescent lamp starter. Because of this, fluorescent lamps can now be manufactured in various sizes, shapes, and watt ratings. In addition to this, the fluorescent lamp has become easier to maintain.

What is the importance of the electronic ballast?

The ballast is an essential part of the fluorescent lamps, whether they come in various sizes, shapes, watt ratings, whether the lamps have them built-in or come as separate components. Without the electronic ballast, the fluorescent lamp will not function. The electronic ballast has created opportunities for various lighting designs. Now we are seeing fluorescent lamps that look like spring coils of light, various lengths and shapes. All these to add beauty and style to the home and workplace.

Dimming Function

In addition, the electronic ballast must be included in order to dim a light source. They are also more reliable, although, pricier than magnetic.
