I decided to swap my yellowish Phillips fluorescent tubes for some new daylight Sylvania fluorescent tubes. Despite that both are the same length and wattage, when I put in the Sylvania tubes, there was a lot of flickering. Also, it was very dim; I almost couldn't read. When I swapped the old Phillips tubes back in, everything went back to normal.
What is the cause of this? Did I just get some really bad tubes?

I tried re-installing them many different times with the same problem. However, there are no problems with the old ones - I ended up having to put them back in.

Sounds like you need a new ballast in your fixture and it's very possible that you got a bad lamp. Try putting one of the yellow lamps with one of the daylight lamps and then switch the daylight lamps to see if one of them doesn't work. More than likely though.......you have a ballast that isn't compatible with daylight lamps.

Yup some tubes take a different ballast. Look at the marking at the end of the tube. Does it say T8 or T12? The need different starter/ballast.

Could be, or maybe you just didn't install them *exactly* right. Those things can be finicky.
