4 Switchable LED Lighting Levels of 9W/4.5W/2.3W/0.2W, A19 for Medium Base Dimmable Daylight White, 60W Equivalent Incandescent Light Bulb, for Type E26, E27, 820lm, Color Temperature 6000K

Works as expected. I just haven't found the right place to put it yet.

Very competitive price compared to similar bulbs. In addition, not many 4-ways light bulbs with a low Watt in the market.It’s easy to operate by switching on and off. I tried the bulb in the upright/Ikea floor lamp and the ceiling. All of them work perfectly without any problem for a few weeks. The difference between the brightness levels seems more obvious on the ceiling than the upright floor lamp.I like to use the brightest level whenever I work at home. The 2nd level provides prefect brightness for watching TV or hanging out with friends. When I am out and about my house at night, I turn it to the 3rd level and it only costs 2.3 W to provide similar 2nd level brightness. Lastly, I barely used the 4th level as I like it dark at night. But I think it should be good for a night light.

too dim for work

These bulbs are as advertised. You easily change the lighting levels by turning it off and on again, repeat for each level. The four levels lighting is not bad but the two levels in between seems almost similar to me. And it's not as bright as I expected. It's a nice white color light though. But I preferred the "3 Switchable LED Lighting Levels of 10W/5W/0.2W" or http://www.amazon.com/gp/product/B00LKMVW4K/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 over this one.

It works as described, although the difference between the highest and next highest wattage isn't too discernible. My main disappointment is that I didn't get the daylight bulb which I ordered, I got the soft white bulb instead - I hate soft white bulbs!The seller sent me a daylight bulb which I have been using since 2015 and it's been through several power outages and brown outs (after the first one I thought the bulb had gone bad - brightening and dimming, but I turned it off and it came on and worked!) and it's still working! I love that I can get a bright light if I want one (I usually use it on the 2nd or 3rd setting) in a pendant light fixture over my bed.

I really do love these light bulbs...they're perfect for reading! I put together an antique photographic reflector on a light stand thinking I'd have the coolest looking reading light, but I couldn't find a light bulb that would be dim enough to use since the reflector intensifies the light. When I found these bulbs I was reluctant to buy, so I initially bought one. The bulb worked so well, I immediately ordered a second one. The light output is a very clean white, almost as ease as reading by window light. I use the third setting on the bulbs to read by: 2.3 watts. This was a great purchase!

Love these bulbs! Not sure what the other reviewers are saying about not much difference in light levels there definitely is. Of course the difference between the 2 medium levels is less than highest to lowest by far but there is a noticeable difference. Maybe if you just had one bulb it wouldn't seem that way but i have replaced my ceiling lights with these and if you have several in the same room the difference is considerable. I've replaced all my ceiling lights with these and while it wasn't cheap I love the end result. I've fought with other LED bulbs and LED dimmers and they never worked to their potential. These do exactly what they say they do.

This bulb is great! Works just like described. I use it in my sons room for regular light and at night it works as a night light. I bought a second one for my room, it's bright when needed and I can dim the light when watching tv.
