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.

A:

 Sun Pulse lamps are the recommended choice for use in the Lumatek e-ballasts. These are available in metal halide only, so if hps is desired Lumatek High-Par lamps will suffice.
