I replaced all the bulbs in my house with fluorescent bulbs a few years ago, and now I'm replacing the fluorescents with LED bulbs. The best I've tried so far is the Philips 10.5-watt Slim Style Dimmable A19 LED Light Bulb ($(removed)), which has 26 LEDs in it. One of my favorite things about it is the shape — it looks like a light bulb with the air let out. I made a quick video so you can see what it looks like.
Despite the odd shape, the light it gives off is even and steady. It does a poor job with a dimmer, though — it strobes annoyingly. Anyone know of an LED bulb that you can dim without strobing?
