Number of Lamps
Magnetic ballasts are a legacy technology and use inductance to transform the line voltage to the voltage required to "fire" or excite the gasses in a lamp. Electronic ballasts use a variety of starting methods, and are more efficient than magnetic ballasts in converting input power to the proper lamp power and operate fluorescent lamps at higher frequencies, resulting in an overall lamp-ballast system – increasing efficacy 15% to 20% over a magnetic equivalent.
Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.
For ballasts and fixtures, height is the measurement of total vertical distance from the top of the product to the bottom expressed in inches.

Q & A
Wondering how many amps this fixture puts out?
Asked on 11/16/2011 by Anonymous
The amperage is difficult to determine. The ballast will have the amps listed on the label. This can vary depending on manufacturer and type of ballast used. The amps will also vary depending on the voltage. The higher the voltage, the fewer amps the fixture will put out.
