Great CFL bulb . . . so far, anyway,
I tried the GE, was not too pleased. So I just got a couple of the Sylvanias and I prefer the Sylvania.
("Osram" is only found in small type on the box -- seems to be a division of Sylvania).
The GE comes on rather dim (at full power). It takes over a minute to get to full brightness. But the Sylvania is nearly instant-on -- comes on fairly bright, gets to full strength in a couple of seconds.
As with most dimmable CFLs, apparently, neither gets really dim -- both go down to about 50%, I'd guess.
And I was either lucky or Sylvania has fixed the buzzing mentioned in an earlier review -- mine don't buzz at all. Neither did the GE. (I wonder if that might be caused by an old or faulty dimmer switch.)
Assuming it lasts as long as they claim, these seem great to me!
