I spent a couple of hours last weekend fixing the floodlights on our garage. It seemed like a good idea to shed a little light on our property after dark in the interest of Homeyard Security.
“Ah, ha,” I thought, “while I don’t want those compact fluorescent bulbs in the house because of the buzzing, the mercury, and the genotoxic effect on my DNA, I don’t mind hanging them outside if they really only draw 1/3 the power of incandescent bulbs.”
So we picked up four CFL floodlights that glow with the equivalent of 75-watt standard bulbs while only using about 25 watts of power. Best of all, the packages promised 7 Year Life Guaranteed! At $7.50 a bulb, you’d hope so.
Taking into account that the dawn to dusk lights burn about 9 to 10 hours a night and the seven years of guaranteed life was based on using the bulbs 3-4 hours a day, we still should have expected at least two years from these bulbs.
Two of them died in less than five days.
When they say these bulbs are “green”, I think they mean for GE, Philips, Sylvania, and Wal-Mart.
