I have three of these lightbulbs on an exterior pole light, and the resulting light is stronger than the street light at the end of the driveway. They are long-lasting (at least one year, exposed to the temperature changes of the outdoors and being on all night), the light is clear and powerful, and the sip energy (the previous incandescent installation was using more for a single light than the whole post now, and it was less luminous).

Rated 5 out of 5 by SILVERSURFER Great for indoor grow.
Great lumen count and they produce a little heat which keeps plants happy.

Rated 5 out of 5 by BrandonO Very nice bright white light!
I purchased these for my workshop since it was poorly lit by lower wattage and lower Kelvin CFL's. Boy did it make a difference! It's bright enough now that it's hard to tell the difference between these CFL's and good old-fashioned sunlight at high noon. I've only had them in a month, so I can't say how long they last yet, but so far so good.

Rated 5 out of 5 by raindc5 Great light output.
I needed 6500k and great lumens. I use this as continuous lighting in my photography. I am very satisfied with the purchase.

Rated 5 out of 5 by AnthonyD Works great
I got this along with two 5K and a 4.1K to create a wide spectrum light source for photography. All bulbs work great and they give good lumens (2000 each) per dollar payed. However, I did switch to the 105W versions because 8000 lumens in total are not enough for photography (but will turn any room bright for casual use).

Rated 5 out of 5 by ajvenom Best so far
When I first bought affordable lower color K cfls, they were not that strong and so I always use a the next size up when converting over. IE I use a 75 equiv. cfl where a 60 watt standard bulb was or 120 Equiv. cfl for 100 watt. That's the only sizes I use. From there on I use from 1-75 clf or 1-120 clf or 2-75 cfl and if I need a lot of light 2-120 cfl. I use 6500k through out my main rooms until the others wear out, because I like the whiter light and my wife likes it for making crafts. She can see the differences in color shades of the thread and materials that she uses. They will sometimes sell this type of cfl as a crafting bulb.

Have used this cfl for years now and I dont know how they can make money at it because they almost never need replacement! I use these as isle lights in a very large Automotive museum. Glad I switched from incadesant
