Tools and Hardware Reviews of GE 21710-3 15-Watt (65W Equivalent) Energy Smart Floodlight Dimmable R30 Light Bulb, 3-Pack
Customer Review: Advantages of CFLs over incandescent and dimmable CFLs.
Summary: 4 Stars
Advantages are less energy usage and less heat production over incandescent bulbs but they do cost more. I would buy this one rather than the dimmable CFLs which only dim about 20% (Sylvania 10%, Philips 20%, GE20%) and cost about 3-4x as much. Don't buy expecting them to dim like incandescent bulbs, because the way they dim is by producing harmonic distortion (changing the waveform to one where less light is produced) which can cause flickering and even without noticeable flickering possibly even headaches or eye strain in some people. So go with the nondimmable CFLs instead.
