High Failure Rates, December 15, 2009
This review is from: 48 Dimmable Compact Fluorescent Light Bulbs.15w=75w
It appears that there is only one actual type of dimmable 23W CFL from China, and they all have very high failure rates, 6000 hour "warranty".
These have been released as "Greenlite", "Harmony" and as "U Lighting America". They have their own "UL" logo to make it look like they're UL listed.
Overall, myself and others included, there is a 50% failure rate on these bulbs within 3 days. I couldn't get warranty on mine that failed the day they were installed. The company's website just lists the bulb information, but there's on contact information. The phone number for warranty is an answering machine with an old lady saying you've reached U Lighting America, leave a message. Several other people have been told that warranty is only good when purchased in California for use in California.
The seller also wouldn't take them back as DoA without negative feedback. Even then, I'm waiting to see.
For most of those that work, the light is crisp white and very bright at full power. As you turn the dimmer down, the light stays the same for about 30%, but the bulbs begin to hum. Past that point, they begin to dim. Past 50%, they flicker. Past 70%, some of them extinguish, or pulsate off and on with substantial buzzing.
For one of them, the light was markedly more pink, but otherwise operated the same way as the others.
So basically, avoid these bulbs. Go for the Sylvania, Earthmate or GE brands with good reviews.Hi

right price poor product, January 14, 2010
This review is from: 48 Dimmable Compact Fluorescent Light Bulbs.15w=75w
The price is right. Longevity is bad.
I have used many other brands. they also have longevity issues. Non of them are what they advertise as far as life expectancy. these are not much worse than other dimmable fluorescent bulbs. They are however significantly less expensive.
I use them commercially. I have over 500 running all day every day.
