A21 LED Bulb, 20W (150-200W Equivalent) 2200LM Non-dimmable and 4000K Cool White, E26 Medium Screw Base Light Bulb for Bathroom & Kichen, 4 Packs by Youtime

These are freaking amazing for the light output and the warm white color temperature. My husband, a retired pilot says they're like runway landing lights (hahaha) and very effective for him for shaving. Added a dimmer for the times we don't need bright landing lights and they work perfectly fine with the lutron dimmer we installed. No buzzing or flickering on the low settings. Also very effective for when I'm putting my makeup on or coloring my hair. The A21 size was also exactly what I needed to fit completely inside the globe diffusers on my light fixtures without them sticking out at the bottom. Tried the 100 watt equivalent from Costco but they protruded too much past the opening and looked really retarded. The 3000k lumens on these were also noticeably and significantly brighter than the 3000k lumens on the 100 watt ones from Costco that I returned after finding these. These were perfect in every way. Replaced all my bathroom bulbs with these and added dimmers for mood lighting.

I was very pleased when I received these. They are quite bright, and of course, save a lot on power. About a year later, 2 of the four don't work at all, one emits a very dull blue glow that would make it serve quite nicely as a night light and the 4th is going strong. Basically, I paid over $30 for a year's worth of saving on power (about $1 or $2) and I now have a single working LED bulb that cost me about $30.Your own experience may vary. For me, the most important reason to have these, that they last much longer than ordinary bulbs, isn't true.

Lights are very bright in my garage with 12 ft ceiling, instant on in -38 degree temps in northern Minnesota.Great for shop or garages or where ever you need really bright lights !!

These lights are very bright as promised but they are not "very warm" or yellow as promised...in the photo the three vanity lights are these bulbs while the two in the shower are cfl's not even real incandescent and you can see they are MUCH more yellow than these lights...making these lights look regular white in comparison. Maybe the box they came in was miss labeled? I will likely return the item. Still giving 3 stars because they are VERY bright as promised just not as "warm" as promised.

...which was only three months for 2 out of 4 so far. Should have much longer lifespan!

Most impressed by the color which matched existing incandescent lights pretty well. Just a little brighter than the existing 200W bulbs but not notable unless you are really looking. Have only had a few of them in service for a couple of months at 6 hours a week so I cannot accurately rate the longevity. I am suspecting (hoping) they will last a many times longer than the incandescent due to the reduced wattage and heat in the fixture.

I am very happy with this bulb. It is being used in a basement, replacing a 150 watt incandescent bulb. I tried dimmer bulbs, but they were pathetic. This bulb doesn't seem as harsh as other daylight bulbs that I have used, but then again, I have not tried them anywhere else. I expect to be buying them again in the future.I did not rate the bulb's sheerness since I don't know what that means for a light bulb.

I cannot speak for over all longevity or quality. Because I'm putting them all back in the box and returning them after only turning them on for the 1st time. The advertised color was 2700 K. But next to my 2700 K CFL the color is obviously cooler.Attach is a photo I took side-by-side.The camera does not pick up the color as distinctly between the bulbs. But looking at the color cast on the ceiling as well as the fan ,it is certainly more Cool than Warm.

So far so good. Really bright and the color rendering seems to be good. Be warned that this is bigger than the normal size and it might not fit in smaller enclosures meant for old bulbs. If you are tight on space and want to replace old non led light, look for A19 instead of A21 but you will have to settle for less wattage as a compromise. Not sure yet about longevity so we'll see.

(upated: one of bulb occured flickering) Brand names looks cheap, however the lightbulb itself is not. It's suprisingly good, color is completly fine, not too red, not too green, but true 3000K. Also the brightness is shine.

I would say that this A21 LED bulbs consumes 20W and gives you back 200W With a decent price. Which means 2200 LM!. It gave me full satisfaction indeed.I strongly recommend it to every one.MK

These bulbs are almost too bright. I've only had them install for a week, but so far they are easily as bright as a 200 watt old style bulb. I expect they will fade with age. I have them on a dimmer switch, but its a switch especially designed for LED's

One of the bulbs started flickering in July. Bought the LED lights in February. That should tell you how long they last. This might just have been one bulb that was faulty. But it's not inspiring confidence in the product.I cannot recommend them. Sadly not much option with this 3000K and high lumens.
