I bought two Philips 20W energy savers about six weeks ago. One of them simply glowed a dull orange when I connected it and there was some condensation inside the sealed bulb. I called customer service at bulbs.com and they sent a replacement next-day shipping at no charge. The replacement lamp worked fine. However...

I've been using mine with a lightbrain controller that gives me 7, 10, and 20W on the lamp with a flick of the switch. Yesterday, I noticed that the one I use everyday for daytime running at the 7W level was significantly dimmer than the other one that I use only occasionally, and at the full 20W. The daily-use one was only putting out the equivalent of less than 10W at the 20W setting. The inside was also glowing greenish. Not good.

I'm going to fire off an email to Philips customer service and ask "What gives?"
