Some issues, but overall a good bulb
I purchased one of these Sylvania 13w "daylight" CFL's a year ago for frequent use in a table lamp in our den. If you are expecting a "daylight" temperature from this bulb, look elsewhere. It's 3500k, which is less yellow than the standard 2700k, but is more of a yellow tinged white than the true white I was looking for. This bulb also buzzes, even though the lamp does not dim. The buzzing is annoying when there is no other ambient noise, but not noticeable when the tv is on or people are talking. The start up of the bulb when newer was nearly instant and while it now takes a few seconds to get up to full brightness, it's still fast enough not to be an issue. Despite the problems, the bulb has long outlasted any other incandescent in the lamp, it runs far cooler than any incandescent and uses far less energy than an equivalent incandescent. I'd recommend it to anyone not wanting a true daylight bulb, but something less yellow than normal bulbs offer.

Saves money
We've converted the whole house over to these lights, except for ceiling fans and the like. Give out as much light at 1/4th the electricity AND when the A/C is on we're not trying to heat and cool the house at the same time.....(put your hand at the top of a lampshade and see how much heat a regular bulb gives off).

These things are great!
I am no believer in manmade global warming, I just bought these to brighten up my place and to save money. I put six in the bathroom fixture and it looks like full sun in there. I replaced 6 x 40W bulbs with 6 x 13W bulbs, gained a ton of light and am saving 162 watts! The "Daylight" versions of these bulbs are much whiter and brighter. I am buying 6 more for other places like closets, etc.
