Tools and Hardware Reviews of GE 21710 15 Watt (65W equivalent) Energy Smart Floodlight Dimmable R30 Light Bulb
Customer Review: Works just fine with my dimmer, much lower power consumption
Summary: 4 Stars
I'm happy with these bulbs which I use in my recessed lighting. The dimming works just fine, they don't get quite as "dark" as old-fashioned bulbs before simply turning off but that doesn't bother me. They provide enough light to help my guests find their way to the bathroom at night without being so bright as to keep them awake. I've gotten about a year and a half out of my bulbs with fairly regular use and they still work great. The package says they last 4 years with 4 hours of use per day, mine see 2-4 hours of use per day. I rarely get what the package advertises though. Play it safe and keep your receipt in case these bulbs die too soon.Customer Review: Doesn't dim well in our fixtures
Summary: 2 Stars
I'm a big proponent of CFLs, so when we bought a house with nineteen recessed ceiling fixtures on dimmers, I immediately looked for lamps for them. I ordered two of these bulbs to try them.
Unfortunately, they do not work well in our fixtures. Perhaps it is the type of dimmer switches we have, but they will not dim much. They go from full brightness to maybe 75% of that light level. The incandescent lamps in the adjacent fixtures, meanwhile, go down to a faint yellowish glimmer.
Clearly these lamps will not work in all dimmable fixtures. You may want to order just one and see.
Customer Review: good but don't dim
Summary: 3 Stars
I really like the clean, crisp light that these produce and the delay is not really noticable and can be overlooked. NOTE: package says "dimmable - works with most dimming switches". I have high end Lutron "designer" dimmer switches - the GE 21710 does not dim on this switch AT ALL. 20% would be acceptable but I am at 100%. Unfortunately looks like I am stuck with regular incandescents to get my dimming feature which I use all the time.Customer Review: Get Regular rather Dimmable Compact Florescent Bulbs
Summary: 1 Stars
Dimmable CFLs only dim about 20% (Sylvania 10%, Philips 20%, GE20%) so don't buy expecting them to dim like incandescent bulbs. Also 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 noticable flickering possibly even headaches or eye strain in some people. So go with the nondimmable CFLs instead.Customer Review: Work well
Summary: 4 Stars
While these bulbs do not dim as much as you may be used to with incandescent bulbs, I find they provide a light that is plenty "warm" enough. I have experienced no flickering at all. I prefer these bulbs to the incandescent bulbs I had before, which were too intense. Overall, I'm very happy with them!
