Ok so about 12 months ago I saw those new squiggly energy efficient light bulbs in my nearby Home Depot store and decided to switch over to them to save some money on my electric bill. After about 7 months I had replaced 5 new bulbs that had mysteriously quit working on me. I had saved my literature on them that came with these new bulbs saying they had a 5 and some a 7 year warranty. I called their 800 hotline number telling them about them burning out on me after only 5 months of occasional usage. Their reply was that first I be extremely careful on replacing them in the socket without breaking them as they contain mercury and I would could contaminate my room if they broke. But more importantly I was told that they were supposed to last that 5 years based on continuous usage and by turning the bulbs off and on during the day after day usage it shortens their lifespan considerably. They did offer me a 50 cents discount coupon for my next purchase on them for my inconvenience. These bulbs were based on continuous usage so that means we must have them on 24-7 to last that 5 years so if that were the case then what electric savings the bulbs were to save are lost by having to keep them on all day every day otherwise they fail. Thanks Congress for another job well done. I'm stockpiling a bunch of regular light bulbs and going to sell then on ebay and craigslist when the ban goes into effect and make some mooolah. lol
