If you live in a warm area where you use air conditioning a good part of the year, any savings in electricity produced by the low wattage of the light may be cancelled out by your air conditioner working overtime to cool off the heat produced by LED lights. Compact fluorescents, on the other hand, produce almost no heat. These lights put out an AMAZING amount of heat for their low wattage.

Some of the bulbs I have purchased only lasted two weeks at no more than a couple hours use per day. Very disappointing (maybe 30 hours lifespan). I am a big fan of LED lighting. Choose a bulb that fits the application (lumens and color) and you will be happy. Unfortunately many manufacturers and vendors overstate (I'm being kind here) their products specifications. I have purchased 45 LED bulbs and have had mixed reliability. The good news - some are very reliable. I have five LED bulbs outside that have run dusk to dawn for two years with no problems. The bad news - some bulbs are VERY unreliable. VERY high failure rates. I purchased 12 of one type LED bulb and 12 out of 12 have failed (8.5W product 47856 from LEDLight.com). 100% failure rate. To make matters worse they are refusing to replace them now. Beware of LEDLight.com. This company is selling products that they know are defective. No support for failed LED bulbs. These bulbs are very expensive ($20 - $105) and in some cases last only two or three weeks. They refuse to replace defective bulbs. LEDLight.com is selling known defective products and has bad customer service. ledlight.com, LED, problem, fail, failure, burnout, quit, reliability, unreliable, review LED bulb reliability – HIGH FAILURE RATES

It's difficult as these new technologies emerge to sort out all the factors and get the right apples to line up with the right oranges. I'm personally extremely excited about LEDs and plan on incorporating them into my home in months to come (and my ears did perk up at that price drop you mention.) Also, thanks for providing those Kelvin numbers. From my own experience I know that make a tremendous difference in selecting the correct low energy bulb for the envisioned purpose.

However comparing the two high end LED bulbs to our entry level LED bulb would not be a fair comparison for the LED bulbs our company produces. A better choice for comparison would be our GeoBulb II or GeoBulb-3 LED bulbs. The GeoBulb II (cool white): 446 lumens, >180 degree beam angle, 30,000 hour rated life for the LED’s and a 3 year warranty for $49.95 each. The GeoBulb-3 (cool white): 520 lumens, >180 degree beam angle, 50,000 hour rated life for the LED’s and a 5 year warranty for $99.95 each (a price drop to $69.95 for these is expected soon). Both of these bulbs are UL listed and FCC approved. We also make available on our website independent lab testing results for these bulbs (LM-79 LED standards). According to a document published by the US Department of Energy, luminosity can vary depending on the make and model of the 60-watt incandescent bulb. In their studies they have found the total lumens can range from 340-1010. This means the LED bulbs from all of the above companies fall within this luminosity range. Please note that all of the LED bulbs covered in this article and in this response are not usable with dimmer switches. To further help your readers, when shopping for LED bulbs with a color that matches their needs they should look for Kelvin rating. The following is a basic guideline for Kelvin rating (color temperature): 8000-8500 Blue-Violet 5000-5500 White-Blue (sunlight) 3000-3500 Soft White 2500-3000 Yellow John Wilder www.ccrane.com 800-522-8863 Thank you Rana Williamson for mentioning our company in your article.
