A: HD is pretty reasonable returning items. Contact HD directly.
A: Not sure what you are asking. Does Cree make a floodlight bulb? Yes they do.
A: I just bought this bulb myself and have no idea what is in store for its longevity, durability, or interior workmanship. I would take it back to the place of purchase and simply indicate it may be defective in some way and see what they say. Is it worth making a stink over a single $20. electric light ? Maybe...
A: Call Cree. They are very good about sending replacements.
A: I had the same problem. Go to: http://creebulb.com/warranty .... "Limited Warranty: If this bulb does not operate for 10 years (based on 6 hours per day / 7 days per week of normal consumer use) from date of purchase when used as directed, return the bulb with proof of purchase, register receipt and your name and address to Cree, Inc. (Consumer Warranty), 4600 Silicon Drive, Durham, NC 27703 USA.
A: My guess is that it is another issue. I've never had a buzzing issue with an LED bulb, and I've installed lots of them.
A: I had one of these bulbs in a good fixture without a dimmer. After less than 1,000 hours it dimmed to about a 60 watt bulb and started flickering once in a while. A lot less than the 25,000 hours promised. I checked the fixture again and it was still good so I bought a different brand, an ecosmart, and it works fine. I'm hoping it will last longer than the Cree. By the way, if you read the fine print, it says 100 watt LED bulbs should not be used in a totally enclosed fixture.
A: I have not noticed any buzzing of my 4 installed bulbs of 9 months.
