Excellent size for a 550 lm bulb. These bulbs are bright and fit the fixture which requires a relatively short bulb.

Can't rate the longevity yet. Life span seems like it’s half of other leds, 25000 vs 50000 hrs. Despite all that, they seem to work well. Needless to say.

The dimming is perfect. As far as brightness, it is as bright or brighter than the light bulb it replaced. The fixture is controlled with a lutron dimmer.

These are great! These are good leds for the price. Their eco-friendly design aligns perfectly with my commitment to reduce my carbon footprint. I am using them in a ceiling fan & they look real nice.

Led bulbs provide state of the art illumination. Gone are the days of flying aimlessly around a dimly lit room. Sometimes a moth just wants to turn down the lights and have a relaxing night in.

Lumen/brightness is not the best, even at the highest level of the dimmer control. Looks great until they have been installed for a week and start flickering for no * reason.
