Does a ballast reduce voltage?
Once the arc is established, the ballast quickly reduces the voltage and regulates the electric current to produce a steady light output. Thus, some ballasts have a separate circuit that provides a low voltage to heat the lamp electrodes during lamp starting and typically during lamp operation (Hammer, 1995).
What is a ballast and what voltage they use?
An instant start ballast does not preheat the electrodes, instead using a relatively high voltage (~600 V) to initiate the discharge arc. It is the most energy efficient type, but yields the fewest lamp-start cycles, as material is blasted from the surface of the cold electrodes each time the lamp is turned on.
What is the output voltage of a 120 volt ballast?

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.
How do you check voltage on a ballast?
Test the ballast’s voltage with a multimeter. Attach the multimeter’s leads to the sockets at the ends of the ballast. If the reading is not between five and nine volts, replace the ballast. Adjust the multimeter to measure frequency and replace the ballast if the reading is not between 20 and 50 kilohertz.
What is the difference between a ballast and a driver?
The driver is an electrical device that regulates power to your LED lights. It’s comparable to a ballast for fluorescent lighting systems. In short, the driver keeps your LEDs running safely and consistently, even when the LED’s electrical properties shift due to fluctuating temperatures.
Is it safe to bypass a ballast?
Safety risk The most significant negative to a ballast-bypass linear LED is the risk of electric shock since the sockets carry line voltage.
