Product Description

Finally, a Dimmable CFL that Dims to Low Levels for Poultry! The CFL's hold their high light output throughout the life of the bulb. As you may know, dimmable CCFL's offer a very low light output. This negative aspect has caused many companies to install a third row of lights. This is not required with our high light output models, especially our 23 watt model.Dimmable Range: 100% - 5%Energy Star RatedHigh light output bulbHigh power factor .902700 KSold as a 2 PakAvailable in 15 or 23 Watt

5.0 out of 5 stars The holy grail of CF lights, December 13, 2007

OK, first of all with reference to the previous review, COMPACT in the context of compact fluorescent bulbs means compact as compared to the long tubes which used to be the only option for CF lighting, NOT as compared to a regular light bulb!

The big problem with CG bulbs has always been the inability to dim them. If you try to dima standard CF bulb, you destroy it instantly. Dimmable CFs are the holy grail and they're finally here. I've only been running them for a few weeks, but they work perfectly. SO long as they last as long as they are made to, these things are awesome. The quality of light and the ability to be dimmed is fantastic. Bear in mind: these use less power in the first place, and then when you dim them, they use even less!

I plan to keep adding them until all my lights are CF and then see how my electric bill is affected. Th

I have tried a number of CFL Bulbs and these are by far the brightest bulbs I've used- they also reach full brightness almost instantly with no noticeable "warm up" period like others I have used.

However, they are advertised as "dimmable" and while they do dim it is not useful... they dim from about 70% of max brightness to max brightness... under that 70% level or so they just go to off...

This still would have let me give it the 4th star, but unfortunately there is yet another problem... At any level under 100% there is an audible buzzing sound- it gets louder the dimmer you get, but even at say 90% brightness it's still very noticeable to me, and that was just a single bulb- I had planned on using three of them in a fan in my living room, but I could never use them with the sound they make at the lower brightness levels- I mean, it goes hand in hand more or less that where you want dim lighting (bedrooms, living rooms, dens, etc...) you also need quiet and that would just be impossible with these.

However, I am in no way returning them- they will work excellent in fixtures that do not have dimmers- closets, some hallways, places where they will only be "on" or "off" - much brighter than my current bulbs and will use a fraction of the power.

One final warning, though it didn't affect my rating one way or the other- they are physically larger than a standard 100 watt typical light bulb... I'd say off hand they are probably close to double the size, you need a deep and wide fixture to fit these in, if your regular bulb barely fits these will not. I tried it in a high-hat light I had in my basement that typical bulbs always fit with 1.5" or so to spare, these bulbs stick out below the opening another inch or more.

These bulbs are unique in that they are dimmable. Most CF bulbs cannot be hooked up to a dimming circuit. While this feature is good, keep in mind, they will flicker like crazy when they are not on full power. Also, they have a tendency to hum. I also got a bad bulb in my 4-pack, which only lasted a week.
