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.

Nice & bright w/o harsh glare. Only thing i don't like 100% is the bulb itself is white color instead of transparent. Makes it cute with the design and ease.

The 4000k i ordered, lean much closer to 5000 k branded (philips) bulbs. Incandescent last a lot longer. However, the color temperature is way off in my opinion and by my rudimentary measurements.
