Upgrading a Lighting Circuit and Installing Electronic Ballasts
[ad#block]Electrical Question: I have a commercial building with fluorescent lighting.
- All are T12 light fixture, two tubes per fixture.
- Many of these are multiple fixtures controlled by a single switch.
- I can no longer find the magnetic ballast for these due to the phase out.
- So, here is my question:
- Can I mix and match old magnetic and newer electronic ballast on the same circuit when one goes bad?
This electrical question came from: Bill , a Property Manager from Louisville, Kentucky.
Additional Comments: Lot’s of great information.
Dave’s Reply:
Thanks for your electrical question Bill.
Installing Electronic Ballasts on Fluorescent Light Circuit
- There is no problem with replacing the magnetic ballasts with electronic ballasts, one at a time, light fixture by fixture, just keep track of the type of lamps that are specified on the label of the new electronic ballasts which will most likely be the T8 type lamps.
- The great thing is that you can use the original sockets for the new lamps as well.

Hi Keith,
Replacing a Light Fixture Magnetic Ballast with an Electronic Ballast

I want to replace a T12 magnetic ballast with an electronic ballast but, I am confused as far as the wiring. The magnetic one has black and white and two yellow wires on one end and a blue and red on the other and the electronic has only black and white on one end and one red and two blues on the other. Must I completely rewire the lighting?
