    Important Note

    BEFORE you turn on a dimmable CCFL light bulb...

    Please understand that dimmable cold cathode fluorescent (CCFL) light bulbs will not work properly at the same voltage settings used for incandescent light bulbs. If you simply replace your incandescent light bulbs without adjusting your dimmer, your new dimmable CCFL light bulbs will flicker and extinguish at the low voltage setting. Therefore, we recommend the following procedure when installing dimmable CCFL light bulbs:

    1. Turn off the power to your current incandescent light bulbs.
    2. Replace the incandescents with your new dimmable CCFL light bulbs.
    3. Re-energize the lighting circuit with your dimmer in the "full light" setting.
    4. Slowly dim your new CCFL light bulbs until they just begin to flicker.
    5. From that point, raise the light level slightly until all CCFL light bulbs are operating without flicker at a dimmed level. Set this level as your new "low setting."

    This procedure should prevent flickering, extinguishing at low levels, and early failure of CCFL light bulbs. If, however, these difficulties occur, replace any CCFL light bulb with an incandescent light bulb. The addition of an incandescent or inductive load will stop the flicker, allow a lower light level setting, and should prolong the life of your CCFL light bulbs. Please let us know if we can help in any other way. (3/7/10)

    A-Shape CCFL - 5 Watt - 30W Equal - 2250K Warm White - 82 CRI - 40 Lumens per Watt - Dimmable - MicroBrite MB-500DL is rated 5.0 out of 5 by 5.
    Rated 5 out of 5 by from Overwhelmingly Great Product, Starts Dim I'll start with the bad, this bulb starts off pretty dim. It can take about a minute for the bulbs to reach maximum brightness. However, this bulb has an overwhelming amount of good characteristics. The bulb instantly turns on with no delay noticeable to the human eye\brain. The bulb has a full dimming range, right down to as low as my switch would go. There was no noise at any dimming level. I'm not even using a fancy expensive switch! When ordering I was skeptical about the 2250K warmth claim, but I can tell you that it's accurate. This is the warmest color CFL I've ever used. Its color warmth is consistent at all dimming levels, making it different than incandescent bulbs that get warmest at lower settings. My wife is a light-bulb snob, and she wants light bulbs to look like incandescent if visible. This bulb is remarkably similar to incandescent bulbs in appearance. In fact, I think that most people won't know it is a CFL bulb. The bulb is the same exact length as the bulb I was replacing and they're all perfectly frosted. You can't even see the CFL tube-curl inside, I'm not even sure if it has one in there. The exterior seems to be made of glass and I suspect that the fluorescent coating is applied directly to the inside of that. I bought eight bulbs, and had zero issues. This review was written the week I got the bulbs and cannot give any opinion on the longevity of these bulbs. One word of caution, do recognize that this is a 30-watt equivalent. It's going to be rather dim, even after warming up. The fixture that I'm using it in has 8 light bulbs all hanging down in individual mason jars. This made having such a dim light favorable. Pros: - Instant on - Dims low without flicker or noise - Very warm - Nearly identical to incandescent bulbs for light bulb snobs - Great value Cons: - Very dim when first turned on

    Rated 5 out of 5 by from Highly Recommended I very much enjoy the light these put out ... I have been using and experimenting with CFLs for 7+ years and these finally give me the softness of a true "soft/frosted" traditional florescent bulb ... Very much recommend these

    Rated 5 out of 5 by from Fits in Old Fixtures, Dims Well I have several antique fixtures in my house that I picked up from an estate sale. Unfortunately, when I decided to switch to CFL, the ballast on most CFLs was too wide to fit the neck of the fixtures. But this MicroBrite bulb is perfect! The profile is identical to old incandescent bulbs, so it fits without any problem. Plus, it dims, which is a nice feature.

    Rated 5 out of 5 by from Great bulbs, great price. I've been using these bulbs for about 4-5 years now and have really enjoyed everything about them. I have around 80 or so running roughly 10 - 12 hours a day 365 days a year and only had to changed a handful of them this past month. I'd have to say that large power fluctuations are their worst enemy.

    Rated 5 out of 5 by from Why are these not more well known? These cold cathode bulbs with 2250K color temperature are a great product that deserve more use. I use these 5W units in my antique lighing fixtures. They look fine, and the color is very good. I have all the bulbs that www.1000bulbs. com offer in this 2250k line and like each one. Their dimming qualities are excellent. Another positive is that they produce almost NO HEAT. Even after the bulb has been on for hours, it is easily handled - AMAZING! Living in a warm climate, this is very much appreciated! I am using dimmable LED bulbs in my kitchen. They are whiter in color, but OK for food preparation. However, in my living areas I prefer a more muted/warmer color. The color of these bulbs is somewhat pink and very flattering. I use the 8 watt standard bulbs in table lamps. I use the larger 8 watt flood lamp in can fixtures throughout the house. Once again, they dim very well and the color is very warm - better than ANY CFL bulb I've seen - and despise! And warmer than any LED bulb I've yet seen. The only downside is that the bulb still has mercury in it, and needs to be responsibly disposed of when it expires.
