Already replaced several in halls and offices next to studios.   No supersonic interference noticed.   T8 did reduce the hum getting into studio mics and phone handsets a lot.

 

Do LED tubes make any noise?

Just to be aware, the ballasts may be driving the T8’s with a supersonic frequency that might cause interference.

We have several T12 fluorescents wired to old external magnetic ballasts mounted in another room electric box to minimize studio hum.

 

Is it OK to replace these with T8 wired to new external electronic ballasts mounted in the same place?
