(5 stars) - GE 13 watt CFL bulbs
Have used these for quite some time. Found the best price here compared to local stores. If the savings are as good as advertised I will be very happy. I would say that they are a great value for the money... BUY THEM, its worth it...

(4 stars) - CFL Facts and figures
Things to look on the package:
1. Kelvin temperature (K): The only accurate measurement for the kind of light or "color" of light you'll get. 2700K is pretty close to the "warm" incandescent we are all used to, 4100/4200K is known as "Cool White" (you might look "ghostly under that) and 5,000+ is the daylight/sunlight. If the lamps do not have the K designation, do not buy them - they are the cheaper variety since establishing the K temp. costs more.
2. Lamp Life (Hrs): The life of a light bulb is the MEAN life, that is at the stated hours HALF of them will be dead and HALF of them will still be working. Life can be affected by many factors, one being how many times a day you turn them on and how long they stay on. As a rule, the more on/off's, the less they last.
3. Initial lumens: If it is not listed try another brand. For the typical 60W equivalent it ranges between 700 and 900 lumens. Try for 800+ In general the highest the K temp. (see #1 above) the higher the lumens.
4. Make sure you read what they say about DIMMERS, as well as photocells, timers, etc. Avoid costly surprises.
5. Make sure they are rated for outdoor use - if that's where you want to install them. The environment's temperature has a lot to do with the CFL performance.
6. Buy as few as you can first and redo, say one room. See how YOU like it (allow 90 seconds warm-up time). If you are a male, have your female with you...she might have some objections you can't even think about!

HAPPY HUNTING!

(1 stars) - Bulbs not 60W equivalent
These bulbs are not as bright as they claim. After switching to all CFLs I noticed right away that they were dim. This is compounded over time. My CFLs lost approximately 50% percent of their brightness in the first month. Before anyone questions this I should make you aware that this is the way fluorescent light bulb go out, they dim over time.

I have done research and found out the following:

1. Manufactures are overestimating the brightness of the bulbs.

2. Bulbs are approximately 50% dimmer then Incandescent equivalents.
EX: Incandescent 60W - 126 lux (126 lumen/square meter) CFL 12W ( 60W equivalent) - 77 lux (77 lumen/square meter) as measured by a light meter.

Don't get me wrong. I liked the idea of CFLs, longer life, lower electrical bills, and even though I am no tree hugger they are supposedly better for the environment.

But I now find myself buying more lamps to try to make the room bright enough to read. Does it really save energy if I replace one incandescent bulb with 10 CFLs?

Lets do the math.

1 x 60W bulb = 60W
10 x 13W CFL = 130W

(5 stars) - Awesome enery saving lighbulb
I don't why people are complaining about this light bulb, yes it is bright and it takes a little time to warm up about a min then it turned to white gold color. I love it cause I don't have to replace two light bulb, only 1 already enough to shine my rooms. Honestly, after I installed the light bulb in the restroom, I did not know that my toilet was that disgusting even though I cleaned it every week. But anyway I'm buying another pack to replace my yard light bulb.

(3 stars) - Pretty bright / comparable to incandescent, but slow to warm up...
These bulbs are pretty good, but you need to be aware that they take a minute or two to warm up to full brightness and color. I bet a lot of people return them without giving them a real try after being disappointed by the brightness when they first turn them on.

They look comparable to an incandescent in general, but when compared to daylight they have a magenta cast.
