Philips LED A19 Ultra Definition Frosted Dimmable LED Light Bulbs - Flicker-Free 60w Light Bulbs with EyeComfort Technology - Soft White 2700K Lightbulb - 800 Lumen - E26 Base - 4 Pack

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.

I just got these and so far I'm impressed. I can get them down to 7% with my Lutron Casèta ELV+ dimmer. I do feel disappointed that there is no 3K option though. All I have seen are the 2.7K and 5K options. I did see that Walmart had a Phillips Smart Bulb for $12.99 that goes from 2200K-6500K but I don't want or need a $12.99 smart bulb. I just now checked Amazon and they have a 2 pack for $20.49 which is still insanely expensive. I might be digressing here but I really hate smart bulbs. You almost have to be the only person in the household who controls the lights because as soon as someone flips the light switch, your smart light becomes nonfunctioning. I feel like smart switches are the better approach because it doesn't matter whether someone uses the app or the switch. Either way can be used interchangeably.I noticed that one reviewer has put out incorrect information that I want to correct the record on so that gullible people are not misled. He says that these bulbs are 60 watt bulbs. Obviously this is incorrect. These are 8 watt bulbs. He says that the only color option is 5K which is also obviously not correct because I purchased the 2.7K color option. Both color options are even on the same page. He then goes on to say that that Govee brand goes from warm light up to 6,500 Kelvin. That's great but Philips also sells a light that does that. He thinks that the Govee uses less energy than these lights. Wrong. Govee uses 9 watts and these lights use 8 watts. 8 is less than 9.Amazon does sell an actual 60 watt LED. It's an A21 bulb from SANSI and produces 9,000 lumens. The highest wattage LED light bulb in the world is a 65 watt SANSI which produces 10,000 lumens. The 60 watt SANSI costs $55.99 with a 20% off coupon and the 65 watt SANSI costs $51.09 which is on sale from a retail price of $89.99. Both prices were from 2/8/25.

These bulbs are great, I’ve bought them before. One of the four “burned out” within first week and I had to return to Amazon. Rare occurrence but it happens!
