GE 47478 15 Watt, 65-Watt Equivalent Energy Smart Floodlight 6 Year Life R30 Light Bulb

I've installed several of these to replace traditional bulbs in track lights. I have Lightolier electronic dimming switches and these are among the few CFL bulbs that work with electronic dimmer switches -- regardless of whether or not you actually want to dim them.At full setting the light is very natural, and with their casing you can hardly distinguish them from the original incandescent lights.The dimming setting is disappointing as it only has one setting that is about 80%. And, as noted in another comment, they do have a faint flicker when in the dimmed setting but it is barely noticeable and I haven't found it at all troublesome.(Note - the newer LED lights have continuous dimming at about twice the price with purportedly longer life. However, the one I bought from FEIT has major flickering until it warms up a bit so I'm sticking with these).I've used them for several years (just purchased some more) and they last well. All-in-all they are a good product and a nice way to get CFLs if you have electronic switches.One caution - the electronics at the base of the bulb make the neck significantly fatter than a normal bulb. My 20 year old Lightolier track lights have a shaped casing that narrows at the base and has a little wiring board on the inside. In about a quarter of my track lights it was just narrow enough to prevent the bulb from screwing in sufficiently to make contact so the light doesn't go on. I've been able to fix the problem by pulling out (i.e. raising) the spring contact at the bottom a bit with the hook edge of a paint can opener (with the track light removed of course!).There are also screw-in bulb extenders you can buy that are easy to install. However, these will cause end of the light to stick out a little.

Overall I like these bulbs. I bought them to replace the flood style incandescent track lighting bulbs in the house. (They come on in the morning and are on most of the day) They are just as bright and they give off a more bright white than warm white color. My only complaint is the warm up time, they take anywhere from 30 seconds to 90 seconds to get to full brightness depending on the room temperature. (30 seconds when it is 78 to 80 degrees and 90 when it is 65-70degrees) I am hoping that this does not indicate a shorter life bulb with the huge discrepancy in warm up times.I admit I bought these based on the reviews and the price as opposed to spending double for really high end bulbs where warm up is near instant.-1 star for the warm up fluctuations, but otherwise I am completely happy with my purchase of these bulbs.On a side note: I have been slowly replacing all the bulbs in my home with CFL (if I need 60 watt or more equivalent and LED if less than that (I still feel 60+ watt LED bulbs are a bit overpriced for the wattage) I do notice a slight difference in my average electric bill when swapping out lights, and my bills do seem to shrink when changes are made, I feel these bulbs do pay for themselves if they last 12 months.

I received these bulbs from Franko Lighting. Product shipped fast and was packed very secure. Awesometo deal with. Would not hesitate using products from Franko Lighting again in the futue.

It's worth starting out the review stating that these lights take a couple minutes to fully warm up. They shouldn't be used in a bathroom or any other room that you need quick access to lighting. You should know that going in. I would add that I've used them in my living room and office and it hasn't bothered me at all. Usually once the lights go on in those rooms they stay on for awhile.As for performance, I was surprised at just how close these mimic traditional floodlights. I'd be surprised if you could tell a difference once they've warmed up. The rest of the benefits you probably already know about. It will lower your electric bill and it does help keep rooms cooler as the bulb doesn't emit as much heat. This is particularly nice in the Summer if you want to save a little extra on the AC bill.Overall, I'd highly recommend these to anyone who has a room that the lights are typically not going on or off a lot. A living room or home office works for me, and I'll probably get around to swapping out the lights in my kitchen at some point too. I'd stay away from using these in the bathroom or hallways, but otherwise they are a great and cost effective addition to the home.

This is as good as it gets for CFL bulbs. I don't know if it's the glass enclosure or the bulb itself, but you can barely tell that this is a CFL when you look at it compared to the other incandescent bulbs that are still on my ceiling. GE really does a good job of taking the complaints about CFL bulbs (too bright, too cold, etc.) and making them go away. That said, it is still a CFL. When I first turned it on it took a second or two to warm up. But it wasn't that noticeable, and in the dark my eyes could use the time to adjust anyway. With Amazon Prime's free shipping, it will be even easier for me to grab these one at a time as I need them to replace my original bulbs, and it's great that I'll be able to use one-fourth the energy with something nearly as good.Among GE R30 floodlight CFL bulbs, this is the one you want if you want the shortest warm-up time. It's not dimmable, but for recessed lights attached to regular switches, it does its job well. If you want something dimmable, check out the  21710 . If you want to go even greener, check out the  47478 . It's not dimmable, but it uses half the mercury and lasts about 50 percent longer.
