LED A21 Ultra Definition Dimmable LED Light Bulbs - Flicker-Free 100w Light Bulbs with EyeComfort Technology - Soft White 2700K Lightbulb - 1600 Lumen - E26 Base - 2 Pack

I like this bulb has a full glass enclosure just like the old standard incandescent. That means that in a ceiling fixture with the bulb sideways you don't have a dark shadow line created by a wide plastic base. Cons I can think of is this is a larger size bulb. It is an A21 which is bigger than an A19 so could limit fit in some applications. Also it is not for use in totally enclosed fixtures. I have a 4 bulb fixture with 4 of these lamps and it really lights up the room. These are not on a dimmer so can't comment on that yet. Definitely will be purchasing more of these.

This is the first LED lamp I have tried that doesn’t make me long for an incandescent replacement. Most of the spectrum is present to some degree. There are no surprises illuminating painted surfaces, the light gets “warmer” as you dim it and there is no discernible flicker. I no longer feel the need to hoard incandescent bulbs. I hope they keep improving these, filling out the spectrum even more completely, but good work so far.

These lights do better with dimming and more extreme temperature changes. They have better circuit boards making them more reliable. You get what you pay for when it comes to lights like this. It's cheaper to pay for good ones once.

I purchased six of these bulbs six months ago. Two have already failed. One flickers like crazy and the other one lights at about 10% brightness. I have changed fixtures and they are just broken. What a terrible investment considering the cost. When working these are great leds but their claimed 13 years of use is hilarious considering I'm out 1/3 in less than 6 months.

The back of the box for these (“Phillips 573667”) bulbs says they are not for enclosed or recessed luminaries. If you want a 1600 lumen LED I would suggest getting the “Phillips 576330” instead, which is 1600 lumens but is designed (according to back of its box) to be able to be used in enclosures or recessed light fixtures. And it is also dimmable. The above sums it up pretty well but if you want more details I wrote a little more about the two bulbs below. I bought this because I thought this Phillips Ultra Definition 1600 lumens LED would be brighter than my Phillips 800 lumens full color wi-if LED (model 9290023833A) but surprisingly not really. Looking at the light cast on the floor and in the room from the hanging kitchen light fixture was about the same; the only noticeable difference is that if I looked at this clear bulb straight on vs the frosted one, well this one was more blinding. It does however work with the dimmer and doesn’t buzz or flicker but I will still be returning it because I prefer the quality of the light the other bulb produces and as I said this one didn’t even seem significantly brighter. UPDATE: I bought box of Phillips 100W equivalent 5 way LEDs and set the color to 2700K and they are exactly what I was looking for; they are designed so that can be used in luminary enclosures (says so on back of box) or recessed luminaries so I was able to use two of these under glass of ceiling fixture. I measured temp with glass fully seated and was cooler than halogen or compact fluorescents. The light was nice and bright and looks nice. No flickr and dimmer compatible. The only con is that if the bulbs are uncovered and you are less than a foot away you can hear a slight buzz sound but since these were under glass on the ceiling I couldn’t hear anything when standing underneath. If no dimmer they are completely silent at any distance. So my recommendation for anyone who wants a true 1600 Lumen LED bulb that is dimmable and suitable for enclosures is the: ___ Philips LED White Dial Flicker-Free Frosted Dimmable A21 Light Bulb - EyeComfort Technology - 1600 Lumen - 5 Shades of White - 12W=100W - E26 Base - Indoor - 2-Pac ___

Longevity is an unknown, but they still work as of today.

Our 116 year old house has some uncorrectable wiring issues in some of the fixtures causing intermittent and sometimes constant flickering and finally I've found a light that is both "dumb" (no extra unnecessary circuitry) and contains a capacitor (to even out the dirty line signals). Super bright and super steady!

I’ll put it like this. When they work I loved em and I have had no issues until today. 1 of the bulbs flickers constantly and only 2 of the led elements are lighting up. It only lasted 8 months. The other 3 I have are working fine as of now but yes I definitely just got a dud out of this batch.

Excelente Producto!

Una de las dos lámparas empezó a funcionar mal después de 7 meses de uso moderado / One of two lamps started to malfunction after 7 month of moderate use.

Compré este producto pensando en que por ser marca Philips tenía garantía de calidad, en su página Philips ofrece una duración muy alta de horas de uso, pero este y otros focos LED que compré de esta misma marca han empezado a parpadear o bajar tremendamente su intensidad aún cuando tienen apenas unas semanas de instalados. En cuanto a el tono de cálido iluminación, intensidad y diseño decorativo estaba encantanda con mi compra, pero sin focos demasiado caros para durar una semana. No se donde podré reclamar garantía de duración
