Frequently Asked Questions

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.

Q:	Which lamps are recommended for use in the Lumatek e-ballast?
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.
