PHILIPSLED 100W A21 2-Pack WhiteDial Multi-CCT (5000K) 1600 Lumen (11.5W = 100W) Dimmable Frosted Flicker-Free Light Bulbs

Really nice light. Good CRI, they are rated on the box at 90, not 95 as advertised here; still very good, and there are no weird color artifacts. I like the glass globe - less plastic is better.These WILL flicker if you use them with certain dimmers. In one of my pole lamps, they flicker pretty bad, and I can't use them. In another fixture with a slide dimmer, it works well with good range, no flicker; some buzzing, but it's my outdoor patio light so it is not in a location where you can normally hear it.The adjustment on the base works as intended, and the selected color temps are pretty accurate. These are great if you are not sure what color temp you want, but don't want to buy a bunch of different bulbs just to try them. They are obviously not intended to be used in place of a "smart bulb."

I’ve been hoping for bulbs like this for a long time. Our LED retrofit recessed lights have had the switchable color temperature for years, but we’ve had to keep a big stock of replacement LED bulbs for everything else because different rooms look better at different temperatures, etc.I’m glad to say these bulbs solve that quite handily, and unlike a lot of the cheap bulbs, the lighting quality is quite nice as well. No flicker, good color spectrum (no sickly yellow or harsh blue cast when there shouldn’t be) and the selectable color temperatures are exactly where they should be. I find the choice of glass for the bulb somewhat questionable, but as long as you don’t drop it, it’s probably not hurting anything (and won’t yellow with age like plastic, I guess).Great bulbs, will be buying more for sure.

Had a fixture that constantly flickered. Tried multiple bulbs but no change. Our builder recommended these bulbs and they worked. No more flickers.

If you buy, maybe think about obtaining from another source. The manufacturer’s packaging only secured the bulb base. The top of the bulbs were unsecured with plenty of room to come loose, causing the bulbs to hit each other and rattle around in the package. It was like two light bulbs stuck in a random box. Might as well have been a light bulb torture test. It’s possible that someone opened the box and took out the top packaging mold (but why?) The manufacturer’s box had no seal on it, so who knows? Add to that Amazon ships the package — two light bulbs, mind you — in nothing but the manufacturer’s box. No shipping box, bubble wrap bag, or even a poly bag.Luckily these bulbs appear to have a relatively tough plastic exterior from what I can tell. Amazingly, the bulbs weren’t broken upon arrival, at least on the exterior. They both turn on, so the seem to work. But if they fail early, how can I be sure it’s not because of the way they were shipped?The bulbs themselves are pretty neat. The kelvin color temperature changing screw on the bottom is a cool feature that eliminates the need to buy bulbs in different color temps, if that matters to you. We like higher kelvin temp bulbs for the home office, utility room, and garage. Lower temps living areas. So this bulb solves that problem well.Other reviews rave about the lack of flickering. I have a floor lamp that uses dimming bulbs to simulate a traditional three-way bulb. The lowest setting seems to flicker with nearly every LED bulb purchased in the last year. LEDs from four years ago don’t have this problem. These Phillips bulbs suffer from the same minor flickering problem as all the other recent LEDs on the lowest setting of my lamp. You may find other flickering issues solved by these bulbs, so much depends on the switch and socket, whether lamp or fixture.The build quality on the bulb seems better than most, definitely makes it seem like the higher cost equals higher quality.At the end of the day, what matters is how long these last with brightness and function the same as day one. Only time will tell if that will happen. If I see premature failure,I’ll update this review. Until then, I’d say get these only if the color changing feature or the Phillips name means something to you.

I don’t know why everybody is not covering these in glass instead of more unrecyclable plastic, but these are great. Bright, excellent color index and look like old bulbs if you have a fixture that you can see the bulb through. Highly recommend.

Flicker-free. 3500K setting (Natural light) is perfect for me. Be aware that these are A21 size, slightly larger bulb than the more common A19, but fit fine even inside the globe of my fan light.[The bulb brand I was previously using flickered terribly whenever my laser printer ran. These bulbs completely fix that issue. All Philips bulbs are flicker-free, but most are either 2700K (yellowish) or 5000K (bluish). Only these are 3500K "Natural Light".]
