What is a digital ballast?
Like all ballasts, a digital ballast regulates the voltage a high-intensity discharge (HID) light or compact fluorescent light receives so that the bulb doesn’t overheat and immediately explode. Digital ballasts use the latest technology in microprocessors to regulate and monitor the voltage a bulb receives.

What are the disadvantages of magnetic ballast?
A disadvantage is that power fluctuations may cause a failure but this can be offset by adding a buffer capacitor. Operation of the ballasts generate heat. Too much heat can damage the components and disrupt current flow to the lamp.
How do I know if I have an electronic or magnetic ballast?
Simply turn the light on, then take a photo of the fixture using your smartphone or digital camera. If there are no dark bands on the resulting image, you have an electronic ballast that will work with direct drop-in LED tubes.
Will any digital ballast work with double ended bulbs?
Standard ANSI s52 electronic ballasts can operate some double-ended bulbs, and is in fact recommended by the bulb manufacturer Ushio to run their Hilux Gro Pro-Plus(link below). However, to run a double-ended bulb optimally, a higher frequency output is needed from the ballast.
How long does an electronic ballast last?
about 20 years
The ballast takes in electricity and then regulates current to the bulbs. A typical ballast will generally last about 20 years, but cold environments and bad bulbs can decrease this lifespan significantly. You can get a new ballast at a hardware store or home center and install it in about 10 minutes.
What is the difference between an electronic ballast and a magnetic ballast?
Magnetic ballasts work at a frequency of around 60 Hz, whereas electronic ballasts work at an increased frequency of around 20,000 Hz. This is why fluorescent lamps using electronic ballasts do not flicker or emit any buzzing sounds. Electronic ballasts are also quite smaller in size and weight.
How do you test an electronic ballast with a digital multimeter?
To measure it, set your digital multimeter to around a thousand ohms resistance setting. Connect the black leads to the white ground wire on your ballast. Afterward, test every other wire with the red lead. When you do this test, a good ballast will return an “open-loop” or max resistance.
What is an instant start electronic ballast?
Instant start ballasts are ideal for use with fluorescent lamps that are not switched on and off frequently. Such a type of ballast provides a high amount of voltage to the lamp when it is switched on, but without pre-heating the cathodes either during the start or while the lamp is lighted.
Can I use MH bulb in HPS ballast?
Yes, you’re allowed to change your mind—at least when it comes to MH and HPS lighting. Although the two fixtures use what are normally incompatible ballasts, conversion bulbs will let you switch lighting types. Some conversion bulbs allow MH light to work with HPS ballasts, and others let HPS work with MH ballasts.
