SWITCH Lighting A23WY1FUS27A4-R Classic A21 LED Light Bulb with 30/60/75-watt Replacement and Frosted Lens, Soft White

This is my first LED light bulb - apparently it's inevitable that these will replace incandescent s. So I'm taking the plunge.This bulb is in my reading lamp which is a three-way switcher. Replacing an old style bulb which I think was 60/100/150 watts - I could be wrong. Whatever a "standard" three-way bulb is.Anyway - this one does work, it does respond to the three clicks on the lamp. The differences between the three levels are definitely not as pronounced as they were on the old bulb, but I honestly didn't expect that they would be based on the description of this bulb.There are three levels of brightness, they all work. I'd say that this bulbs highest brightness is about what the old bulbs medium brightness was. It's certainly enough to read by.The "whiteness" of the light is fine by me.It does get hot, but so did the old bulb.It is heavier than the old bulb. I honestly can't imagine a lamp so fragile that the weight would be a problem, but it is noticeably heavier. Again - no surprise as the description about its weight was fine.All in all I like it. I hope it lasts as long as they say it should.

This bulb casts light in a pattern, not evenly. The glass enclosures of my ceiling light fixtures have ridges, and they greatly exaggerate the light pattern thrown by the bulb, making a dappled or spider-web pattern of light on the ceiling and the upper part of the walls. Other bulbs in the same fixture don't do this. If you want that effect, great, but most people probably do not.

While the bulb itself looked a bit odd and unlikely to deliver the conventional light, it actually outperformed my expectations to a large degree. Sure enough, it does work the same as the original incadedscent bulb in all three positions. There is also substantially less heat generated compared to a regular 3-way bulb.I will have to say that I have had some previous experience with L.E.D. lighting while installing emergency vehicle equipment in my line of work as an electronic /radio tech for the city. So I had learned that L.E.D. lighting could be feasible in professional applications, but I wasn't so sure about domestic use until I tried it.As for longevity or durability, I haven't had the three bulbs long enough to comment at this time. However, the 3-way L.E.D. s have worked flawlessly ever since they came out of the packing. The lighting is just fine.If they do actually perform the specified lifespan, then they will definitely have been worth the money. You must kep in mind that all new technology is pricey in the early stages, but prices will come down somewhat as their use spreads and the scale of manufacturing improves.Yes, I would buy them again.

Positives: bright, warm light. Environmentally friendlier than CFLs. Expected long life.Negatives: Price.My wife and I for years have used CFL bulbs, and were satisfied, though they have their drawbacks. Years ago we replaced all of our Christmas tree bulbs with LEDs, and there was a significant reduction in our electric bill during the holidays. We are within a couple of months of retiring, and we decided to replace the most used bulbs in our house with LEDs, hoping they will reduce our electric bills, and that we will not need to replace them in the time remaining to us. This bulb gives plenty of light at all 3 levels, equal to or better than the CFLs they replaced (we compared them side by side), and the light is warmer than that of the old CFLs. We have not yet received an electric bill since we installed them, so we don't know the impact on that yet. However, when we replaced our old standard bulbs with the CFLs we saw a noticeable reduction in the amount of the bill. We hope to see the same reduction with these and the other LEDs we installed. The only negative is that, as far as I could find, this is the only available 3-way bulb, and thus more expensive than it would be with some competition.

When purchased, this bulb was expensive but did what I expected it to do. However, it has already died. For something this expensive, it should have lasted much longer. When it was working it was great. It just didn't have the quality I expected given the price point. Not recommended.

First the seller is outstanding, very quick support replies!I received my 2 3 way bulbs yesturday and I thought I had a problem with one flickering BUT I tried Mazspeed's suggestion of trying another lamp and it worked! BUT I have tried the good one in the bad lamp and it worked, that is what threw me off and I thought I had a bad flickering bulb.It turned out to be an electronic (remote control) switch I put on the lamp, but I don't use anymore and I also had a bad 3 way switch in that lamp so I swapped it with another lamp. All is working great now!Its amazing on how much you find wrong just by switching bulbs.I also put a watt meter on both bulbs (lamps) andlowest setting = 3.8 wattsmedium Setting = 11 watts on one bulb the other is 11.2 wattshighest setting = 19.9 wattsThe Spiral CFL it replaced (mercury dust filled ones) had 18 watts and produced a little more light than the lowest setting and no way as bright as the middle setting on this bulb, WOW!!!The color is the same as a spiral CFL (not cool or white at all).

I've been using this bulb daily, and for many hours per day, for nearly two months. I am quite pleased with all aspects of it. The warm white color temp is very comfortable for reading and as background light. It runs cool to the touch, and the brightness is as expected at each level.I gave up on fluorescent three-way lamps because they tend to "sing" at a frequency that drive me crazy. As expected, this is silent. It also comes on instantly, unlike fluorescent bulbs.

We purchased 2 of these. One still works the other only works on medium setting. Very disappointed. Since one is currently still functioning, it seems I should receive a replacement in exchange for this defective bulb. I don't see it lasting approx 20 years. 😣
