Query: A Brilliant Idea Gone Wrong

A low energy, high expense, light. I had two of them in a floor lamp and they lasted one and two years. 7 year warranty requires you to return them to manufacturer ($5.00 shipping). That means that approximately every 2 years you will be out $12 + $12 + $5 for these bulbs. Bought 2 Sylvania 150 Watt CFL's at $8 each from Lowes. Brighter and cheaper!
