Tools and Hardware Reviews of GE 21710-3 15-Watt (65W Equivalent) Energy Smart Floodlight Dimmable R30 Light Bulb, 3-Pack
Customer Review: These bulbs work great and will save you money
Summary: 4 Stars
I used some of these bulbs in an overhead fixture that originally used incandescent bulbs. I've used dimmable fluorescent bulbs before so I know that you can't dim them quite as low as a regular bulb. They probably dim to about 20% which suits our application just fine. I've been using the bulbs daily for about 2 years and they're working just fine. I've found that if you turn them on and let wait a few minutes you are able to dim them down further than if you just turn them on and dim them right away.
I'm very happy with the bulbs and even more happy with the money I'm saving on electricity, not to mention that they don't give off a lot of heat like incandescent bulbs do. That can help in the summer when you're trying to keep the house cool and maybe even save a little on the air conditioning.
Customer Review: Extremely Pleased!
Summary: 5 Stars
I purchased 12 of the dimmable R30 CFL bulbs for a 12 light grid layout in our kitchen. The lights fired right up, but the high wattage dimmer on the circuit only dimmed the lights a small amount. I changed the dimmer to a low wattage unit since all 12 lights together now only pull 180 watts (instead of the previous 800 watts) and the system works fantastically! Needless to say I am extremely please. The light is now brighter than before on much less power and can even go dimmer than the incandescent bulbs did on the high wattage dimmer. I even like the effect of the slow smooth startup. I have now bought a total of 20 CFL bulbs and have not had a problem with a single one. 5 Stars and two thumbs up from me!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.Customer Review: finally a cf we can live with!
Summary: 5 Stars
Maybe they've changed this bulb since those early reviews, we don't have any problem with warm-up time. The first time we turned it on the bulb was sort of dim and bluish, but after an hour or so it lit up bright with a nice warm glow. Now it comes on at the flick of the switch with no delay at all. The rate of dimming isn't quite as smooth as with the incandescents, you can't get it on as low, but other than that it's perfect for us. NO BUZZING!Customer Review: Work well, a few cons
Summary: 4 Stars
These work well, for the most part. They are brighter then the 65W incandescent bulbs they replaced, but they take 5 mins or so to get that bright. They dim, but only about 50% or so, and in our case we can't turn the dimmer more then 70% off or they flicker. All in all, they do the job we wanted, run cooler then what they replaced, and since they stay on 24 hours a day in a business setting the warm-up period doesn't matter much to us.
