I placed a few of these things in non-crucial parts of the house (bedside lamp, garage). The bedside lamp had a noticeable buzz/hum. The garage lamps was not as bright as the incandescent bulbs they displaced.
My sister-in-law gets headaches from regular fluorescents (die to flicker). When she visits next month I’ll see if she gets them from the screw in kind.
I agree that LEDs are the future if they can scale them up enough to truly light a room.
“The bedside lamp had a noticeable buzz/hum.”
Hm...none of my lamps exhibit this. You must either have a bad bulb or perhaps the wiring in your lamp should be looked at.
Aha! So I'm not the only one hearing that hum and noticing less light. Home Depot was wrong about the source of my humming noise and I intend to let them know it.
