THD In Light Bulbs


I have replaced a 40w incandescent light bulb with a 12w LED light bulb. The new LED is way brighter. In fact, the box says that it's a 75w equivalent. The box also shows something interesting:

Power Factor >.90  
THD: <35%

I've read that LEDs are essentially diodes. How does this affect noise in the mains? Do LEDs inject more, less, or the same amount of THD into the mains as incandescent/fluorescent lights?

@orthomead I have my stereo on two parallel 20amp lines with no other household devices.  Unfortunately I could still get some electrical feedback from other devices on different lines (when I turned on an LED light I got a slight music dropout, perhaps due to the router I was streaming music through?).  Eventually I got a power regenerator (an old Elgar as recommended by Atmasphere), put it on one of my lines, and that stopped the problem.
