PHILIPS LED 60W A19 8-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,

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.

Update: Four of 16 have failed. Either flickering or going dim orange. Installed in various fixtures around the house. Totally unacceptable to fail in less than 45 days. Philips customer service is terrible also. Taking days to weeks to respond. Amazon helped once at least but that was within my initial 30 day period.Like others, these bulbs seem to have a high failure rate out of the box. For me, it was 1 bulb out of 16 that was bad. It flickered a few times when turned on and then was stuck in orange mode. I contacted Phillips customer service via e-mail and three days later still no response. Amazon ended up having to make it right and they did A+.The bulbs that do work are great. The design is nice, the size is standard and fit all my fixtures. The brightness was as advertised also. Overall a good value if they last.I recorded my old Cree bulbs and these new Phillips bulbs at 240fps on my iPhone 14 Pro. I took 3 videos each. The Cree bulbs had tons of pulsing/flickering. The Phillips bulbs that maybe the tiniest amount of visual flicker on 1 of the 3 videos.I wanted the new Philips Ultra Efficient bulbs, but they are still priced a bit too high for outfitting a whole house.Overall 4 starts due to 1 failed bulb and non-existent customer service.

These are great bulbs for the house. Note that you may want brighter ones for certain task lights.They have a nice glow, and according to some guy on Youtube with a light spectrum measurer, they have low blue light wavelengths (unlike nearly all other LED bulbs).I have these all around the house and have been so happy with them.I ended up finding these after a bulb was stuttering on/off while being dimmed. I assumed it was the dimmer, but then thought to try a name-brand bulb first. Turns out it was just the big-box-store brand of bulbs are not as good as I had hoped. This bulb solved the problem.

I bought these in November 2023 and really like them; flicker-free dimming, warm cooler. However, 8 months later one of them began to flicker and only output about 50% of the light. Let's see if Philips will stand by their 5 year warranty!
