    > I will never buy another 6500k bulb. They are labeled Daylight, and I bought several for general use, for the "daylight" color, and for the birds. The 6500k bulbs have nothing to do with "daylight", and I had to remove all but one pair in a ceiling lamp in the living room, that has to go through a Tiffany stained glass fixture.

    > This gross error in labeling can be found wherever CFLs are sold, it is a manufacturing problem, it has nothing to do with Bulbs.com, a distributor. The 6500k color is FREAKY. Your browns and yellows are way off. In real daylight, all colors are correct.

    > I bought a number of these 5000k color bulbs, and they are as far to the blue as I will go with *artificial* lighting. Through trial and error I have also discovered that I can also use the 4100k color. I have chosen the 5000k for the bird room. I always hated the sickly yellow of the average incandesent bulbs, which are now going extinct, and were too hot anyway.

    > I am happy with this purchase, this is a good price on a 100w equivalent.

    > For your info:
    > Warm White: 2700k color, too yellow
    >Cool White 4100k color, right in the middle
    >Bright White 5000k color, bluish but OK
    >Daylight 6500k color, nothing daylight about it. Downright freaky

    >Will order from Bulbs.com again. Good prices.

    I use these bulbs in my kitchen, living room and office. Absolutely love the way they brighten up the room. My kids do their homework in the kitchen and these bulbs provide great lighting for reading and writing; same for computer use in the office. I bought 16 of these bulbs in February 2012 and as of today, 7 have already popped. Some popped within 3 months use, some within a year and some within 2 years. That's more than a 40% failure rate in a span of 2.5 years.

    You will not get 12,000 hours out of these bulbs so consider this and the cost before purchasing.

        These high (K) bulbs are the only way to go. Our home was using low (K) bulbs for years, we really didn't know the difference, the only thing I did know was that CFL bulbs were horrible, ie. dim/yellow glow. After some research, and discovering that we knew nothing about CFL lighting, it became evident that we were using the wrong ones (for YEARS). I guarantee if you use these high (K) bulbs, you will never go back to standard light bulbs again. Also, do some checking----you won't find better bulbs/prices anywhere else. Thanks Bulbs.Com.................you have my business.

            I bought these bulbs to brighten up 3 rooms in my house. These worked perfectly. I didn't want a warm color light, because they mute the colors in my house. These 5000k bulbs worked great. I bought some 2700k bulbs for the bedrooms.
            These are some of the brightest 100 watt bulbs I have ever used.

                      Why is this bulb "not recommended for use in enclosed fixtures"? I have been using 26w CFL in my outside fixtures for years.

                        A:

                        This compact fluorescent includes an integrated ballast. When used in enclosed fixtures, the heat will build up and affect the life and performance of the bulb. It is recommended that the fixture (especially indoor fixtures) have some ventilation.
