My problem with them was a "strobe" effect.

They would flicker very fast, even after they'd been on for over 30 minutes, and the resulting strobe effect was dizzying to say the least.

My wife didn't like them either.

Then when we replaced them with the old incandescents, no problem.

I'd like to be earth-friendly, but not at the cost of barfing when I turn on the light.
