To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
These bulbs all make an audible buzzing noise when installed. I do not have dimmers in the house. Just standard light switches. They're basically unusable as a result, unless you live in the Amazon rainforest, in which case the buzzing sound would be drowned out by the ambient noise provided by fauna and weather conditions which, if nature documentaries/Hollywood films are anything to go by, is deafening. But then you'd probably have bigger things to worry about, such as the Brazilian wandering spider.
Anyway, don't buy these bulbs. I'm honestly not sure if this is a Phillips problem or if the bulbs are in some way 'knock-off' (which has been suggested by several other reviewers). That would certainly explain the very low price, though I would question the viability of a business somewhere manufacturing exact replicas of Phillips lightbulbs. Stranger things have happened, I suppose.
Just got these today. Hearing a buzzing where halogen bulb of equivalent wattage (60w) did not. Disappointed. Tried other LED 100w bulb and don't hear the buzzing. The bulbs get very hot around white plastic in just 30 mins or so of use. This happend with the first 3 bulbs I tried each in a different room. Havent tried the other 3 in pack yet. Going to return these as seem dangerous. Also as one other reviewer says, the bulbs do look different to whats on the packaging.
Bought as an Amazon offer of 2 x 6 packs for £20 which seemed like a good price for a recognisable brand. The bulbs are actually made by Signify which is the name Philips lighting changed to a few years ago and are manufactured in China. I think almost all LED bulbs must be made in China nowadays as I’ve never come across any made anywhere else. The energy rating of these bulbs is F which doesn’t sound that great but this is under the new labelling system which came in on September 2021. Under the previous labelling they’d have been A+ which sounds a great deal better. These bulbs give just over 100 lumen per watt and consume 8 watts to give equivalent lighting of a 60 watt incandescent bulb. To be A rated under the new labelling they’d have to consume around 4 watts so to my mind the potential saving to a typical domestic bill between F rated and A rated isn’t that significant . These bulbs are described as warm white (2700K ) and are ideal for the majority of domestic uses though for a home workshop / office set up I’d go for a cooler white (3500+K). I’ve frequently been disappointed with the longevity of LED bulbs, often experiencing lifetimes comparable with the old incandescent type. These bulbs are rated as 15,000 hrs / 15 years but at this price if I can get at least 2 years use from them I’ll consider them worth the money. I notice that some reviewers have experienced buzzing noises from the bulbs but of the 3 I’ve installed to date all have been completely silent.
These seem to be fake as if you look closely things dont match the manufacturers pics. The name on each bulb is way of centre. The materials look cheap and the name is smaller than wat the manufacturers pics show.
In September 2018 I bought a 6-pack of these 8W bayonet cap LED bulbs from Amazon to replace the 60W filament lamps in the wall fittings in my lounge. This week, one of the LED replacements started to flicker, then died after less than 4,000 hours' use. On their Amazon web page for this product the Philips boast is "Never change your light bulb - lasts up to 15,000 hours". We had used 60W tungsten general service lamps under identical conditions in those same fittings for over 40 years and,despite their often-quoted 1,000-hour rating, they sometimes achieved lifetimes of up to 10 years. So I'm not at all impressed by the Philips' claim and I'm left wondering why I've paid more money for an inferior product.
Initially I figured these would be great but now, not so much. It turns out LED lights dim with age! So although they are slightly better with power consumption I'm certainly not going to get 10+ years of life from them. Saying that, 1 year after installing I have saved the cost of replacing them in electricity costs.
I replaced all lights in the house with led lights which wasn't all that expensive really (but way more than when energy saving bulbs were selling for as little as 10 p at one point)
I haven't experienced any failures after a year except for one dimming in brightness, so make what you will and hope this helps.
There are so many cheap alternatives with such mixed (and usually fake) reviews out there but with the Philip's LED brand at least you know that high standard's are being met and when you're dealing with electricity it's always better to go with a company who has the funds available to rigorously test their bulbs and quality-control procedures before releasing millions of them with potential legal action's and recalls resulting from dangerous failures. In particular, these LED bulbs look and feel extremely well-made and if there's any problems in the future I promise to update this review.
For a brand like Philips these are extremely disappointing. Each bulb gas a quiet buzzing sound. Have tried the bulbs in different houses. It is the bulb at fault. Unusable. Cannot obtain refund as return window closed.
As other reviewers of these light bulbs have found some to be faulty on arrival, I tested all of mine straight away. No problems with any of them. They provide a very decent light (60W) while consuming much less power and it's good to know they will save me money if they last the course, especially as two of them are left on all night, every night. I've had these for a number of weeks now but am not really in a position to judge longevity though as I say, so far so good. Very good purchase.
As other reviewers have noticed, these bulbs create a very audible buzzing sound that doesn't go away. They are fine as a ceiling light in a room with significant ambient noise, however, they are far too loud for a bedside table. I suspected a problem with my circuit, but I swapped them out with another LED bulb and the sound went away.
Update - I've since compared the bulbs that buzz to apparently identical bulbs that I purchased about 2 years ago. The bulbs that buzz are distinctly lighter, and have more imperfections on the base. Despite the fact that these were supplied by Amazon I'm beginning to suspect that they are either fake, or Philips have updated their design in a manner that creates the buzzing. I've swapped the bulbs between light fittings and the old bulbs do not buzz. The printed spec on the bulbs is identical (although it's hard to read on the new bulbs due to the light print).
