Most lamps in my house are outfitted with CFLs. But frankly, if each lasts only 4 years (rather less than expected and observed lifetime), I’m using less mercury than the old fever thermometers of my youth, which usually did not last even that long.
But if you break one, we’ll report you to the EPA, you might as well sell the house...
I got one years ago our of curiosity when they first came out. Pathetic light (although they increased wattage I see), long lasting, looks faggoty, it’ll be the only one I buy. I’ll switch to “alternative” power/fuel lights before I buy another one just because I don’t like being dictated to. There.
