PHILIPS LED 60W A19 4-Pack Ultra Definition Daylight (5000K) 800 Lumen (8W = 60W) Dimmable Frosted Flicker-Free Light Bulbs

I have not received anything in any form for this review, I bought and and paid for these bulbs with my own money, without any reimbursement before or after purchase and review, not even a coupon. I bought a 40 watt bulb of a different type and brand not long ago, and all of a sudden I started getting headaches. I know it sounds funky, but I don't usually get headaches. I started thinking about my daily routines, what I have been eating and drinking, and etc, The only thing different was that light bulb. I know it sounds hinky, but I absolutely can't find anything else that was different, Welllllll, that started my research nose twitching. So I started looking up how light can affect your health. Bingo! I found a lot. The flicker rate, color temperature, and the Color Rendering Index have a whole LOT to do with health effects. I read articles, and research papers, and yeah, I watched YouTube videos for ahhh, maybe a day, or a day and a half. Once I get my teeth in something I wring out as much info as I can find. I had ordered an incandescent. It was delivered on February 21, 2025. I put it in my little desk lamp, and turned it on. I thought nothing more about it. I use that lamp on my desk to light the room. I cannot stand bright glaring lights shining down on me. I turn the lamp to reflect off an off white wall, and it gives me all the light I need. If I need to read something I just have to twist the gooseneck and point it at the book or paper that I need to read, and I can control the way the light illuminates exactly how I need it. Well it took a couple of days I think, and I started getting headaches. I wondered where they cam from, I'm not usually a headache person, It's unusual enough for me to go through the hassle of figuring out why, No change in diet, not drinking more coffee, not eating anything different, no different cleaning supplies, no new fabrics. I could not find anything, Except the light bulb. Well, I have been researching since then, and I am convinced that the light bulb I had been using was the problem, I watched a few videos along with reading the research papers on light, check out MedCram on YouTube for a real licensed medical doctor on sunlight, and red light, infrared, and near infrared light, on health. Boy that's an eye opener for sure. I also watched a series of videos where a bunch of bulbs were tested with meters, for everything from flicker rate, to color spectrum, light temperature, and the Color Rendering Index. All of these are important if you want the best sun like light you can get to enhance your health, especially if you spend a lot of time indoors. I encourage you to look at this information, there is more information than I can write here. You can read, look and listen as many times as you need to to get the information straight in your head. Anyway an March 8, 2025 I ordered these bulbs, They arrived today, I immediately opened the package, and put one in my little lamp. I kid you not the headache is mostly gone. The 60 watt bulb is just right, It has a bright WARM light, not a stark harsh white light, so it is not hard on the eyes, The temperature is 2700 Kelvin, which helps keep the blue spiking in the light spectrum, that LED lights are known form, to a low level. 2700 - 3000 k temp is very early morning light. 4000 k is between very early morning light and before noon. 5000 k is noon bright, and 6500 k is full sun at noon on cloudless days. Just keep in mind the higher the kelvin the MORE blue light it is emitting even if it is balanced by a spectrum of the colors. It's the blue light you want to avoid as much as possible because you get a lot of it, from phones, tv's, tablets, and computer screens. SO you want as close to natural sunlight as you can get. The High CRI means that all the other colors of sunlight are present also. So you are getting a full spectrum of light. Look a the color spectrum that shows on the meters in the videos, this bulb has a CRI index of 95! The only other bulbs I could find with that high a CRI were 2 companies, one was 19.00 each, the other was 100.00 for 4 bulbs. In order to get a 95 CRI it has to have all the colors not just one. Incandescent bulbs have a good CRI but it is skewed to the red side of the spectrum like most LED's have a lot of blue. And incandescent bulb DO flicker, watch the video and the meter testing. The one guy even tested for "dirty electricity" with an EMF meter and different bulbs showed different amounts. These bulbs are a good deal for what you get, the specs that rival a 19.00 bulb, the complete color spectrum, 800 or so lumens, low flicker rate, and low emf emission. Overall, I am very satisfied with these bulbs No more headaches! These bulbs are also glass, not plastic, so the look like an old fashioned incandescent bulb. I still say, don't take my word for it, look around for information and make up your own mind. I am giving these bulbs five stars for: form, function, and value for money,

No flicker at all. None. Zilch. Nada. Color temperature reads just about the advertised 2700K, and while I don't have a good way to measure it, the color rendering looks good to my eyes. I didn't include any dimming results, but FWIW, they do dim beautifully. Arguably better than incandescent, in my brief testing. The first image is from the flicker app that I used for testing. As you can see the flicker reading was 0.. There was no dimmer in the circuit. For comparison, the second screenshot is from a 40 watt G15 incandescent vanity bulb, also with no dimmer in the circuit - that 25-year-old bulb is from the golden days of light bulbs - the best bulb from what I always considered to be the best brand. The third is from a GU10 LED in a range hood - 58% flicker! It's the store brand from a big box store.

I bought two four-packs of these Philips Ultra Definition Soft White (2700K, 800 lumen) bulbs after seeing them recommended by The Hook Up a couple of years ago. We bought our house in December 2019, and I didn’t replace any of the original LED bulbs until they started failing in 2023. Those were extremely cheap, builder-grade bulbs, and despite being bottom-tier, they lasted roughly four years. I bought my first four-pack of these Philips bulbs around late 2023 and the second in 2024, and started replacing the originals as they failed. At first, these bulbs are fantastic. The color quality and clarity are noticeably better than the builder-grade bulbs. The light is warm (without being yellowy '1970s Wisconsin Lampshades and Wood Paneling Everywhere' warm), natural, and very comfortable for office work. From a pure lighting-quality standpoint, they’re excellent. The problem is longevity. In my office alone, I replaced three bulbs several months ago. One has already burned out completely. On two others, the “cool” side failed early, leaving an odd warm-only light. A one of those only turns on intermittently, and it's on the way out - so 2/3 failed in short order. I’m already looking at replacing all three again less than a year later. For comparison, the cheap builder-grade bulbs lasted from 2019 to late 2023. These have lasted from roughly late 2024 to early 2025 before showing major failures. At the price per bulb, that’s exceptionally poor value. They look great when new, but the lifespan is nowhere near what you’d expect from a premium LED. If Philips can’t match the durability of bargain-basement builder bulbs, that’s a serious problem. If you care mainly about light quality and don’t mind frequent replacements, you may like these. If you want reliability and long-term value, I’d look elsewhere. (Photo Caption: 3 Philips Ultra Definition bulbs from the August 2024 pack - they replaced 3 Edison-style bulbs on the same day. It's February 2026, and 2 have been failing since Spring 2025. Note the color difference - they looked fantastic, like the left-side bulb for about 6 months, then 'the cool side' failed and they look like this now.)

Hands down the best LED bulb I've ever used. Great color and brightness. Superior dimming capability. ZERO FLICKER!!! Is it weird that I'm this excited about a light bulb? Maybe. Do I still want to shout how great it is from the rooftops? Absolutely.

I bought a 4-pack of these lightbulbs 13 months ago. I had been having problems with a group of 3 hanging fixtures over my kitchen island; when the lights were dimmed rather low one of them would be dimmer than the others, and the one on the other end of the row would be brighter than the others. If I dimmed them very low the dimmest one would go out while the other two remained on. And there were flickering issues as well. I work with a master electrician and had him to my house to do some other electrical work, and I asked him about the problem with these fixtures. He checked everything out and said the wiring was fine, and that I should try a better quality lightbulb. I had been using the Home Depot EcoSmart bulbs until that point. On his advice I switched to these Philips bulbs, and the problem was immediately resolved. All bulbs are equally bright regardless of how low the dimmer goes, and there is no flickering. I thought a bulb was a bulb, but there really is a difference in quality. The only reason I give these 4 stars instead of 5 is that after 13 months one of them started flickering and I had to replace it. But overall I'm very happy with them.

I cannot believe I’m writing a review for a lightbulb, but these are something special. Genuinely the most migraine-friendly LED bulb I’ve ever used. (For context: I get chronic migraines, and Bright cold light and strobe effects are some of my main triggers. I also have annoyingly high perception of flicker effects). Dropped into some random desk lamp designed for incandescent bulbs, I expected there to be at least a little discernible flicker I’d have to deal with. But there’s NOTHING!! Genuinely, not even a hint of flicker!! It’s just this nice, soft, continuous glow like you’d get from an incandescent bulb!! The light is pleasant (bright without being harsh) and has a slight golden touch to it (distinctly warm, but not overly orange or yellow). Great color rendering too. The glass housing is a very nice touch. I bought these to use as a grow light for a desk plant (you can use any broad spectrum white light for plants). My “plant shelf” is the small overhead cubby that came built into my cubicle. I have a desk lamp rigged up inside with one of these bulbs. I’ve had the light powered continuously for over a week, and it is barely warm to the touch. Like lukewarm water temperature. This tells me the LED’s inside are being treated kindly (not running too hot). Plus, I can have it right up close to my plant (a pothos cutting that is just starting to root) with no fear of burning the leaves or making the ambient air too hot. The plant seems to enjoy it! I can’t comment on dimming because the lamp fixture I’m using doesn’t have dimming capability. So I don’t know if flicker effects become noticeable at low power, as is typical for LED’s. For beautiful lighting in a small space, Definitely worth every penny.

How far are we really like them I use them on a dimmer I had some other brand bulbs that went out and we figured we would try this Philips brand the lighting quality is very good I like how they delay with no flicker very energy efficient and for the price it's a good value for the money. The only reason for four stars and not five is I have not had them installed very long so I do not know the longevity

Okay so first these have great CRI which is effectively how accurate color are when the lights hits/deflects off objects. Back in the day when incandescent 60w bulbs were the norm we had perfect CRI and never thought anything of it and many early Philips LEDs were like 80 or so and even now there are tons of cheap bulbs sub 80 which is terrible. Now I've tried other cheap brands but have had by far the best luck with Philips when it comes to LED bulbs, there are some lights in my house on all the time and I still get years out of them. The longevity of these bulbs is not amazing, I've even had a couple straight out of the box new where the light is dim and very orange. I even thought it was my one fan fixture since I swapped a brand new bulb in and it was dim and terrible looking like the one I was replacing, then 40 minutes into that I was like hey why don't I just try it in another light fixture and yup it's the bulbs. Went through 8 bulbs in just under 2 years in only two light fixtures and neither of these ones are on all the time. I'm going to buy a 4 pack one more time since I originally ordered two 4 packs at once at the end of 2023. I'm wondering maybe if they just had a bad batch since I know Philips knows how to make led bulbs and to do it well.
