Electronic ballast does not hum as much as a choke. Minute hum of electronic ballast is the small inductor and capacitor producing an oscillation for high voltage generation,

How do you test an HID lamp ignitor?
For your question, i see the ignitor means the Electronic Ballast. If you want test HID lamp electronic ballast, you can reference Lisun WT2000-HID HID Ballast Tester, this instrument is main for test HID lamp electronic ballast,
What type of a ballast do compact fluorescent lamps use?
a compact electronic ballast in the base of the lamp
Is there a special type of fluorescent light for cold conditions?
Normally its the ballast that's different. Use an electronic ballast rather than a magnetic.
What size ballast do you use for a 4 foot tube?
When the ballast is to be purchased, look at the schematic that is on the label of the ballast. There it will tell you which ballast is good for which lamps and also let you know what length of tube the ballast is good for. Most of the new electronic ballasts allow for multiple connections of different size lamps.
Why do ballast get burned?
Heat is generated in a working ballast because of the current flowing through it. Heat is bad for any electrical/electronic device and will eventually cause it to fail.
Does a tube light glow without starter?
yes..if we replace magnetic ballast with electronic ballast...there is no need of starter if we use electronic ballast.

Why do light buzz?
most likely from all of the electricity flowing through them. Incandescent lights do not buzz. Fluorescent fixtures with a non electronic ballast can develop a buzzing or humming noise. The ballast has a wire coiled around an iron laminated core. As the ballast ages the laminations start to separate and the alternating current going through the ballast makes the iron layers vibrate (hitting each other) causing the hum or buzz sound.
How do you rewire a magnetic ballast F96T12 fixture to work with a new electronic ballast?
The end sockets have to be rewired. The schematic for the rewire is on the ballast label.
Why does magnetic ballast take more power than an electronic ballast?
Because it wastes less energy in the form of heat.
I've changed the bulbs in a 40 inch fluorescent light fixture but it still goes out. What might be wrong?
It sounds like your ballast is malfunctioning. If it is a magnetic ballast it will probably have tar protruding out of it and the ballast will be very hot. Buy a new electronic ballast. Change the wiring to the end sockets like it is shown on the electronic ballast print that can be found on its label. You will need new tubes for the new ballast. Diameter will be T-8.
What does an electronic ballast do?
Electronic ballast is designed to limit the current which goes through an electrical circuit. This keeps the circuit from overheating or suffering other ill effects from having too much current.
How do you fix an electrical ballast in a florescent lamp?
You don't fix it, you replace it. Sometime buying a whole new lamp is about the same as buying just the ballast.Also you have to get the right one and then follow the colors on the wires to swap it out.Their are electronic ballasts and the older ones that hum.
Why does a Ballast hum?
The obligatory wise guy answer is always "Because it doesn't know the words." If we get by that there are two basic types of ballasts. The traditional electromagnetic ballast hums more than the newer electronic ballast. Fluorescent fixtures have a sound rating that ranges from "A" to "D" with "A" being the quietest. In electromagnetic ballasts the alternating current causes a magnetic field to basically compress the central iron core in a phenomenon called Magnetostriction. What you are hearing is a 60 Hz vibration that can get louder with age. In an electronic ballast the hum is usually much less noticeable and can again come from vibrations induced by the switching happening in the electronic components.Next AnswerThe core of an electrical ballast, like the core of a transformer is made of laminated layers of iron material. This type of construction makes it work more efficiently. The Alternating Current (AC) repeatedly magnetizes and demagnetizes the layers in the core causing them to vibrate. The layers are bound together with some sort of glue limiting the actual vibrations and if properly done there is no humming sound.As the ballast gets older, the glue material weakens allowing the layers to separate and allowing the vibrating layers to hit each other resulting in the humming sound. An old ballast can get pretty loud.
