They consume eight to 10 watts when operating with the lamp in the circuit. The ballast will consume about four watts when the lamps are removed although the ballast is still energized.No, removing the ballast does not make your LED conversion consume less electricity. The ballast is an essential component which converts and regulates power delivered to a fluorescent tube. LEDs also require this power conversion and regulation; it can not be avoided.Electronic Ballasts
On a typical fixture with two 4 foot 40 watt T-12 fluorescent lamps, the ballast consumes about 13 to 16 watts of electricity. Thus the total consumption of the two lamps plus the ballast is about 93 to 96 watts. The most efficient ballasts are electronic, or high-frequency ballasts.

Do bypassing a ballast save electricity?
While there is likely a small amount of additional energy savings using a direct-wire, or ballast-bypass, LED tube, there still remains a safety risk with line voltage going straight to the sockets.
Do fluorescent tube lights use a lot of electricity?
Fluorescent lamps, including compact fluorescent lights (CFLs), use about 75 percent less energy than incandescent bulbs and last six to 15 times as long, according to the U.S. Department of Energy (DOE). But it’s widely believed that these popular bulbs use a lot of energy to start up.
How many amps does a ballast draw?
Generally, most standard outlets have a capacity of 15 amps. When you plug a 1000 watt ballast in your 110 volts power supply, it draws nine amps.
What is the wattage of a 4 lamp T8 fixture?
ANSI considers the 4-foot, 32-watt T8 lamp to be a rapid-start lamp, but it is commonly operated using an instant-start circuit in which the two pins on each end of the lamp are electrically connected or shunted together.
Is it cheaper to leave fluorescent lights on all the time?
It takes more energy to start a fluorescent that it does to run it, so leave the lights on all the time to save money on your electric bill. When you turn on a fluorescent light bulb (correctly called a “lamp”), there is a very brief jump in current when the ballast charges the cathodes and causes the lamp to start.

Does a ballast use electricity if no bulbs are present?
No, unlike LEDs, the fluorescent bulb itself (or rather the tube) can not use power when it burns out, however, the ballasts may use a trace of energy whether or not there is a bulb installed.
Why do my fluorescent lights burn out so fast?
There are many possible reasons why a light bulb burns out quickly: The power supply voltage may be too high. Bulbs may be loose or connected improperly. Excessive vibrations may be causing the filament to break.
Do I need to remove ballast for LED lights?
An LED light does not require a ballast because it uses a component called a “driver” to regulate the power going into the bulb.
Will LED lights work with a ballast?
No LED bulbs require a ballast, although some are engineered to work with an existing ballast. You will find ballast-compatible or “plug-and-play” LEDs that are designed to replace linear fluorescents, compact fluorescents, or HIDs. Incandescent and halogen lamps do not require a ballast.
