Tools and Hardware Reviews of GE 21710 15 Watt (65W equivalent) Energy Smart Floodlight Dimmable R30 Light Bulb
Customer Review: good replacement for indoor flood lights
Summary: 4 Stars
Overall, these bulbs are good replacements for typical incandescent flood lights. The amount of light they put out is comparable.
These are also the first fluorescent flood lights I have found which work with dimmer switches. So a couple plusses in their favor.
There are a couple important differences between these bulbs and a typical incandescent bulbs:
1) they are more expensive
2) they have about a 1/2 second 'pause' when turning on. When hooked up to the same switch, an incandescent bulb will come on first, by maybe a half second. More of a small annoyance than anything, but the expectation is immediate light when you flip the switch
3) there is a 'warm up' time before these bulbs emit their full light output. Probably 90 seconds before they are 100%. They start at probably 70%.
4) these bulbs work with a dimmer switch, but the levels are different than a typical bulb. They probably range between 20% and 100%, whereas a typical bulb would go from 1% - 100%.
Overall, I am satisfied. They use less energy, put out the same light and work with dimmers.
Customer Review: hey don't dim! Back to the drawing board, GE
Summary: 1 Stars
I have dimmable recessed lighting in three main rooms facing north and west that are almost always light, even during daytime. So CFLs could make a major dent in our electricity bill, and ease the need to change bulbs in hard-to-reach locations. Dimming is critical in all locations.
Tested on _all_ dimmers in our home - including two new ones - this bulb did not dim whatsoever. I tried leaving it on for a while, but the bulb ran a apparent full capacity even when all the incandescent R30s are barely lit. Moving the dimmer has a binary effect on this bulb - just on or off.
One slight pro with this bulb is that unlike other CFLs, I've noticed that this one is at full brightness right away.
Customer Review: Hardly Dimmable, Short Life
Summary: 1 Stars
Hoping to save some money on electricity, I bought a couple of these GE Dimmable CFL bulbs for our kitchen.
When the light comes on, it isn't as bright as regular flood light bulbs, and with our dimmer, it doesn't dim and brighten properly either. I figured I could deal with it, since we have a dimmer, and the regular CFL flood bulbs aren't for use with dimmers. Unfortunately, my bulb lasted LESS THAN ONE MONTH. Are you kidding me? I have never had a bulb die that quickly! And, at more than ten dollars a bulb? Not saving any money there.
I have contacted GE Lighting to report this problem, but I certainly can't recommend investing your money in these bulbs at this time.
Customer Review: Dimmable CFL but it doesn't really, uhhh.... dim...
Summary: 2 Stars
I'm a major fan of CFLs. I have them all over my house. I finally installed a dimmer with my newly installed recessed lights in my living room and looked all over the place to find these hard-to-find dimmable CFLs. I bought them and tried them along side my soft white incandescents. At full brightness, it is clearly whiter and brighter hands down. Unfortunately when I started dimming, these GEs barely dimmed at all. I would be generous to say that they dim to 50% brightness. What good is a light that's advertised to be dimmable but doesn't really dim? I'm going to return them in hopes that GE or some other company will develop one that actually dims as well as incandescents.Customer Review: Nice light, but does not dim
Summary: 2 Stars
The light output luminosity and color temperature is great. It is much better than my original 65W incandescent.
The lamp is dimmable, but I could only get it to about 70% on both my 600W Lutron linear slider and 1000W Lutron rotary dimmer, which is unacceptable. I did not notice any buzzing or flickering when dimming, though at its lowest setting, the CFL tube on the inside had a plasma ball look with the gasses swirling around and a slight purplish tint.
The real deal killer was that it is 1/2" longer than the existing bulb and even with my Halo recessed can on the largest bulb setting, it stuck out beyond the baffle trim and looked awful.
