I went to pick these up, but the fine print on the packaging stopped me. Even Sylvania can't claim they are brighter.
Although that have a table on the back of the pack that says something like 30-40% brighter (so-called "edge-to-edge" brightness). There's that conspicuous asterisks that leads to the fine prints that basically says when compared to a regular bulb's brightness averaged edge-to-edge after the bulb is old enough to lose 30% of its brightness. So basically they are saying, new bulb is brighter than old bulb.
Whiter light does give the appearance of brighter though.
Then the life chart. One bar out of 4 for the standards indicates like 25% of the life of a standard bulb.... yes, they have a 1 year warranty... but still... what to do while I'm waiting for a replacement to be shipped?
