1 10,000 hours-the typical life expectancy of a CFL bulb. 2  1000 hours-the typical life expectancy of an incandescent bulb. 3  $0.12 - the average cost of energy per kilowatt hour (Kwh).
By the end of this month our engineers will have tested five brands of 15-watt mini-spiral CFLs, equivalent to 60-watt incandescent bubs, for about 5,000 hours each. (A typical incandescent bulb lasts 1,000 hours.) The tests will continue until more than 50 percent of the test samples for a given brand have burned out.
