Dimming ballasts typically work by controlling the amount of current going through the fluorescent lamps. They adjust the voltage supplied to the lamps, which in turn regulates the light output. This allows for the dimming functionality in fluorescent lighting systems.

Does a fluorescent ballast work in a DC V supply?
No, fluorescent ballasts are designed to work with AC voltage supplies. They require the alternating current to function properly and cannot operate on a direct current (DC) power source.
What ballasts are used for LEDs?
LEDs typically do not require ballasts like traditional fluorescent lights do. Instead, they usually use drivers to regulate the power supply. These drivers convert the incoming electricity to the voltage and current needed to power the LED lights.
Can a glow stick glow work if you freeze them?
Yes, freezing a glow stick will slow down the chemical reaction inside, making it glow more dimly and for a shorter period of time. Once thawed, it will return to its normal brightness.
Which light bulb uses more energy?
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
Are fluorescent lights a form of electromagnetic interference?
Yes, fluorescent lights can emit electromagnetic interference (EMI) due to the high frequency electronic ballasts used to power them. This EMI can potentially affect nearby electronic devices or sensitive equipment by causing interference or disruptions in their operation.
Why do fluorescent lights stop working in the summer?
Many older fluorescent lamps are equipped with ballasts that don't work properly in hot and/or humid weather. Newer fixtures can be bought with solid-state ballasts that resist high temperatures and humidity, and replacement ballasts are available to retrofit existing fixtures.
Why do you need a special light dimmer for fluorescent lights?
The ballast of a fluorescent lamp (whether modern electronic or conventional large inductance) will cause a kickback voltage when the lamp starts up that causes electrical breakdown and destruction of the standard dimmer's Triac (a solid state switch). There are some special electronic ballasts that don't do this and will work with ordinary dimmers (just don't expect a linear dimming effect like you got with an incandescent bulb). The special dimmers that work with ordinary ballasts use special high voltage switching circuits with extra protection components to prevent this damage. This makes them more expensive.
Why choke is not used in CFL bulbs?
CFLs have two main components: a magnetic or electronic ballast and a gas-filled tube (also called bulb or burner). Replacement of magnetic ballasts with electronic ballasts has allowed the development of smaller lamps directly interchangeable with more sizes of incandescent bulb. Electronic ballasts contain a small circuit board with rectifiers, a filter capacitor and usually two switching transistors. The incoming AC current is first rectified to DC, then converted to high frequency AC by the transistors, connected as a resonant series DC to AC inverter. The resulting high frequency is applied to the lamp tube. Since the resonant converter tends to stabilize lamp current (and light produced) over a range of input voltages, standard CFLs do not respond well in dimming applications and special lamps are required for dimming service

Where can one purchase many 18 watt ballasts?
There are many places where one can purchase 18 watt ballasts. Some of the best places to purchase 18 watt ballasts would be places like Amazon or Best Buy.
Can an incondescent lamp dimmer be used to control a fluorescent lamp load?
No, incandescent lamp dimmers are not compatible with fluorescent lamps. Fluorescent lamps require special dimming ballasts to control their light output. Attempting to use an incandescent lamp dimmer with a fluorescent lamp can cause damage to the lamp and dimmer.
Can different Ballasts be connected together?
No they can't
What circuit is employed in a tubelight?
Fluorescent lamps are usually operated on ac circuits with a frequency of 60 Hz. However, higher frequencies permit higher-efficacy lamp operation along with ballasts of lower power dissipation per watt. Consequently, systems have been developed for the operation of fluorescent lamps at frequencies from 360 to 50,000 Hz. The most important high-frequency ballasts operate the lamps in the 25-kHz range, are lighter in weight, can have flicker-free light output, and will continue to be more cost-effective as the cost of electricity increases. Electronic technology permits these ballasts to be made with more features, such as dimming and low-cost remote controls, enhancing their overall performance value.
Is a digital ballast better than transformer ballasts?
Digital ballast are much more efficient and more reliable than the traditional transformer ballasts. Digital ballasts are more efficient at producing light than a transformer ballasts. The digitals also run much cooler than transformers and are much more silent. Though some user may enjoy the transformers more, digital ballasts are more popular and are sold more often online. Yes, a ballast transformers has two special secondary windings to provide the proper low current. Also, Ballasts can operate more than one type of lamp.
What is the least effective way of dimming tungsten lighting for colour photography?
Rheostat. Dimming by rheostat changes the colour temperature of the light
