The main attribute for these bulbs is their brightness. They are bright white and do a great job of illumination, better and brighter than a standard 60 watt incandescent bulb. Very pleased -- much brighter than our existing kitchen fixture bulbs.

It looses its brightness to almost null. However, the bulbs are noticeable smaller in the actual bulb shape.

Not sure on longevity, but will update if there's an issue. It is difficult to find a bulb of this style that gives over 1000 lumens.

Nothing on the bulb or on box indicates anything about actual wattage, lumens, etc. Measured with lux meter 5 of these bulbs produce less measured output than 6 60w incandescent bulbs!

Started flickering. Sort of wet is it was emitting something liquid. This item keep blinking!

Do not buy this product. Do not recommend at all. This manufacturer has no quality control. Very disappointed with my purchase.
