We've had a few questions about these ballasts looking "used". These ballasts are industrial grade, and thus, they are not shiny and new looking. The ballasts we sell are fresh from the factory and 100% brand new. They're not the best looking item we sell, but they are reliable HID workhorses!
Q. What is the difference between these new Magnetic Ballast Systems and the Electronic Ballast Systems?
A. Electronic ballast is smaller and higher performance than the magnetic ballast.
Q. What is the difference between a "probe start" and "pulse start" ballast?
A. Without getting technical, a "pulse start" ballast has an ignitor which helps start the lamp, while the "probe start" does not have an ignitor. Most ballasts sold in MH fixtures here in the U.S. are "probe start" (ANSI: M57, M58 or M59).
