I stay away from the cheaper multi packs you see in the big box stores.
I agree with you about the failure rate of those. The color also sucks with the dull yellowish light. 2700K is what they are.

I started spending a bit more for them online and getting a more whitish color in the 4400K to 5000K range. Haven't had any failures. And the color is better. I'm not saving any money though at $8-$10 each.
