In November, I replaced a pair of light bulbs in one of my ceiling lights. Tonight, the light bulbs in the other ceiling light also burned out. However, instead of replacing the burned out light bulbs with incandescent lights, I installed a pair of U Lighting America dimmable compact fluorescent light bulbs.
So, this is the first time I have ever used dimmable CFLs. At full power, the dimmable CFL works just like a standard CFL. At anything less than full power, the dimmable CFL hums. At the lowest dimmer setting, the dimmable CFL flickers. So, while the CFL is technically “dimmable,” the humming and flickering basically renders this feature useless.
The only upside to this is that I now have two ceiling lights side-by-side with different types of bulbs that were installed at relatively the same time: one with incandescent light bulbs and one with dimmable CFLs. So now, it’s a durability contest between them to see which one lasts the longest. Theoretically, the CFLs should win. However, theoretically, these CFLs are dimmable as well.
