If your fluorescent lighting is displaying any of the signs below, it could be a symptom of a bad ballast:
- Flickering.
- Buzzing.
- Delayed start.
- Low output.
- Inconsistent lighting levels.
- Switch to an electronic ballast, keep lamp.
- Switch to an electronic ballast, switch to a T8 fluorescent.
Additionally, do you need an electrician to change a ballast? Yes. As a matter of fact, you do need a lock out tag out device in place for changing a ballast. 'An electrician is replacing the ballast on a fluorescent light. The electrician uses the light switch on the wall to de-energize the florescent light.

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.
How do you test a ballast?
- Turn off the fluorescent fixture's circuit breaker inside the breaker panel.
- Remove the fluorescent bulbs from the fixture.
- Remove the ballast cover from the fixture, if the ballast is not already exposed.
- Set the multimeter to the ohm setting.

- Remove the fixture cover's screws with a screwdriver.
- Visually locate the electronic ballast inside the fixture.
Why do fluorescent bulbs burn out?
Every time a fluorescent lamp is turned on in a cold state, more emission mix is used to get it going. That means lamps that are turned on for lesser periods of time -- usually less than a three-hour time period -- will find themselves burning out due to less emission mix than those that are kept on for a longer time.How do you test a fluorescent starter?
How to Test Fluorescent Starters- Turn the power off.
