I purchased these bulbs February, 2017. They were installed in a open globe fan that is rarely used. Two of them have failed. When I attempted to file a warranty claim with Philips they have NO record of this bulb on their website. I understand products can fail, but offering a warranty and making it impossible to file a claim is bad business.
I leave you with this quote from Philips. "No results were found. Please try a different search."
So I've actually purchased this set of 16 bulbs twice about two months apart. We just closed on our new house and there are lots of lights to switch out to LED. So we've been taking it slowly. The first set, about 9 of the bulbs have the buzzing problem that people are talking about, the other 7 seem to be fine. Also the first set was a little cooler in color than the second set. The second set however was perfect. They had no buzzing and they were more warm yellow like expected. I even swapped out some of the older ones with the newer ones in places I wanted the warm yellow light. I'm actually going to buy a third set as there are still some straggling bulbs to be changed.
Looks like Philips is still up to their old accord the "Phoebus cartel" I installed these lights 13months ago 25% have recently failed and I do not have much hope for the rest now. I bought other LEDs at Home Depot long ago that are cycled more and on longer as night lights that I have not had one fail yet. Those shortly became unavailable or I would have a house full of them. As and Electrician I sampled many early LED lamps and trims. Out of the thousands I have installed none have failed as fast as these lamps that I chose to use in my kitchen etc... If the others had I would get constant calls from clients who are unable to change a trim etc...
Buy knowing they won't last 10years if you use them no more than the spiral florescents phillips sold us before did.
We thought to do a little experiment to test these LEDs for heat buildup and longevity so we placed one in a covered porch overhead light fixture that stays on 24/7. The fixture has a sealed screw-on heavy glass jar style cover with cage. Monitored the fixture for heat build up after 8 hrs on, then on overnight. The bulb cover itself is plastic rather than glass and does not heat up when lit. The transformer in the base however does warm up but we did not find the temp too warm to touch. Compared to a lit incandescent bulb which is untouchable at all times and for nearly 30mins after being turned off, LED bulbs are no hotter than a Starbucks paper cup, uncomfortable but not a burn hazard. We did not find our type of enclosed fixture subject to heat build up. The electrician that installed our porch light stated that the max wattage rating for a fixture is rated for hot incandescent bulbs. If you stay within the wattage rating for your fixture you won't get excessive heat build up for an enclosed light fixture so the low wattage high lumens LEDs won't be a problem. In our house, in overhead room lights and lamps they are great. Recommend "warm" white.
These bulbs work great everywhere with one big exception: the garage door opener. When I put them in the garage door opener the door wouldn't close unless I was within about 5 feet of the door, and even at that distance it took several tries to get it to close. The problem is that they put out RF interference and since the bulbs are right next to the radio receiver in the garage door opener, they overwhelm the signal from the door opener.
This problem manifests itself in being able to open the door OK, but not close it. The reason for the difference is that when you press the button to open the door the lights are usually off and thus not causing any interference at the moment the signal is received unless you are reopening the door shortly after closing it before the lights go off. Conversely, when you attempt to close the door the lights are usually still on from having opened the door just a few minutes ago, thus interfering with the close signal.
I had to go back to the incandescent bulbs in the garage door opener until I can find some LED bulbs that don't put out this kind of RF interference.
Wow these are super BRIGHT!! We are slowly replacing all of our ordinary light bulbs with LED light bulbs so this was kind of a test batch purchase for us. We were pleasantly surprised and will be coming back for more! FYI the 5.5 watt light bulb (40 watt equivalent) is much brighter than most 40 watt bulbs, I'd say it gives off about as much light as a 60 watt light bulb so keep this in mind when replacing bathroom light bulbs, unless you're going for the super bright look.
These arrived in good condition and well packaged. I was pleased to see that they are about the size of a traditional incandescent bulb. Most of the lights in my house have decorative covers, and the CFL bulbs we've been using are a bit bulkier that normal light bulbs, so some of the covers either had a tight fit or wouldn't go back on, leaving us with bare bulbs. These lights, however, fit perfectly, and now all my covers are restored! They are also quite a bit brighter, perceptively, than hte CFL's. This may be due to the "daylight" part, I'm not sure, but it was quite nice to see the rooms all lit up again they way they were supposed to be, and at an even greater energy savings than CFL's.
Bought 4 of the 16 packs. As of right now I will give them 5 stars I've used about 24 of them and have yet to have a DOA or issue with any of them in the week I've used them. They were replacements for traditional halogens and there color matches them pretty well but they are noticeably brighter, the picture I took shows a bit too much yellow which isn't the case in real life. As for reliability I will update my review if I notice any issues in the coming months and continue converting the rest of my house. I have no flicker or buzzing issues, and all of them seem genuine and show the Phillips logo on the sides.
It should also be noted the boxes for these show a 10 year life span at 3 hours a day usage. Much less than the industry average which is odd but acceptable for this price range, that estimate seems much more realistic as well. I'm more interested on how its electronics will last in the long term. We shall see and I will update my review if any fail in the next year
Have had these since Decembers of 2018 and only had one go out so far around July due to being on a bad dimmer switch (not designed to be on them I know) It started flickering quite bad in any light bulb socket. After deploying them in my entire house, my entire house is now LED only and with Cree or Philips bulbs. These are a great affordable bulb and because they've lasted without problem for 8 months, I can surely recommend them.
These are the worst led bulbs I have ever tried. They all pretty much last 6 months and then either start to flicker or just fail completely. Old incandescent bulbs last longer then these. Philips should be embarrassed to put their name on these bulbs. Buying these have made it so I will NEVER trust the Philips name again at any price. They did come at a "good price" but for a non dimmable bulb in large quantity, it didn't seem too far off. However, it turned out to be too good to be true. I have other LED brands that seem like they may make the 10 year lifespan and have already reached well into that. With these I had high hopes, but I would have been OK with maybe 3 years lifespan. 6 months is totally unacceptable. Considering the lack of quality, these are WAY overpriced. DO NOT BUY!
