Will a T8 ballast work with T12 bulbs?

Can you replace a ballast in a fluorescent light?
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.
How do you know if ballast is bad?
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.

How do you change a ballast without turning off power?
Remove the wire nut from one of the power wires and carefully strip about 1/2 inch of insulation from the end, making sure not to touch the end. Hold the ballast wire next to this wire with the stripped ends parallel but not touching. Quickly slip on the wire nut and screw onto the ends.
Can a ballast be repaired?
Sometimes, the colour coding on the old ballast does not match the new ballast. We recommend that you always hire a qualified electrician to have a ballast repair or ballast replacement service done.
How do you check a ballast if it works?
One probe of the multimeter should touch the hot wire connections, while the other touches the neutral wire connections. If the ballast is good, an analog multimeter has a needle that will sweep to the right across the measuring scale. If the ballast is bad, then the needle won’t move.
What causes fluorescent lights to not come on?
If a fluorescent tube neither lights nor flickers when switched on, first check to see that the fixture is plugged in and that no fuse has blown or circuit breaker has tripped. If this does not help, try wiggling the tube gently in its sockets by rocking it back and forth and from side to side.
