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.
I would buy again from this company just because they stood behind the product. Replaced 35 watt halogen.
Since they are smaller, they are lighter and easier to replace. Nice warm color, comes on instantly, dims smoothly. These are very bright and have a nice warm color.
