I installed my very first CFL Bulb in the loft today. It is not that I am not energy conscious, it is that we have ZWave controlled home lighting system in the Loft. Non of the CFL's, and most of the LED bulbs do not work with electronic dimmers. Only the bathrooms' lights are normal switched lights. So I installed my first 3.7+ years CFL there. Let's see if it last that long. Listening to OnPoint last week, the editor-in-chief Kimberly Kleman said we should keep the receipt and call the manufacturer on it if the bulb fails.
