Larger Philips bulb
One thing to consider when buying LED bulbs is that they come in different shapes than the familiar Edison bulb. The recently released Philips 17-watt A21 LED light on the left is noticeably larger than the 12-watt version on right because it has a longer heat sink. It's longer than a traditional incandescent, too. With a ruler, I found that the Philips 17-watt was about a half inch longer than an incandescent bulb. That's significant enough that I wasn't able to fit the Philips bulb into a small, overhead light fixture.
