these from lowes for like $8 work great and reliable and dim quite low. have a ton of them in my house with caseta dimmers with no neutrals.

[Link: usa.philips.com] these work well too. they have a second bank of led's that fire up to alter color temp. they have more of an orange look when it switches banks similar to an incandescent when its dimmed. However it is a little noticeable when you ramp up the dimmer and it switches from just the one bank of leds to the other. but all in all not a bad bulb and dims pretty low.

with all i modify the low end trim on the dimmers to get as low as i can reliably without flicker. I generally also kill the bulb then hit dimmer up once numerous times to make sure it always turns on. If it doesn't do it 100% of the time then i go up a little more on the trim.
