Why do some wall lights have electronic ballast
And then the larger metaphor is the traditional motor star Angle You can look at the definition and principle of the ballast and the perceptual component, OK?
Why do some wall lights have electronic ballast
One: it is the lamp that will carry the ballast. Two: why is it a electronic ballast, not a inductive ballast? The electronic ballast is lighter than the inductance, the light of the small power, the electronic ballast can meet the requirement, and also the energy saving. The price is low. So, this may be why some lights start choosing electronic ballasts. I don't quite understand why you ask this question, why do you charge electrons instead of the inductance, or why you want to install ballast... O... Anyway... Electronic ballast appears, although not as stable as electricity, but it also has the advantage of electric inductance. Especially energy efficiency. The power of a wall lamp is generally small. So, it's a very smart choice to use an electronic ballast.
