Q: What is the difference between an electronic ballast and a magnetic core and coil? A: Electronic ballasts, also known as "digital", utilize a internal microprocessor that converts a higher efficiency of energy to the bulb using less power from the ballast. The result is a higher quality bulb life, and increased output of light.
